Von Mises stress is a critical concept in the field of mechanical engineering that measures the stress state of a material subjected to a complex load.

In materials science and engineering, stress is defined as the force per unit area that is exerted on a material. When a material is subjected to an external force, it experiences stress, which can lead to deformation or failure if it exceeds the material’s strength. Stress can be categorized into three types: compressive stress, tensile stress, and shear stress.

When a material is subjected to a complex load, the stress state cannot be determined by a single stress component. Instead, it is determined by the combination of three principal stresses acting on the material in three different directions. The von Mises stress is a scalar quantity that represents the equivalent stress produced by the combination of the principal stresses.
The von Mises stress is a useful measure for predicting when a material will yield or deform permanently. It is commonly used in the design and analysis of mechanical components and structures to ensure that they can withstand the expected loads without failure.

The von Mises stress is calculated as the square root of the sum of the squared differences between the three principal stresses. It is expressed mathematically as:

σvM = √{[(σ1 - σ2)^2 + (σ2 - σ3)^2 + (σ3 - σ1)^2]/2}
where σ1, σ2, and σ3 are the principal stresses.

In summary, von Mises stress is an essential concept in materials science and engineering that provides a measure of the equivalent stress state in a material subjected to a complex load. By using the von Mises stress, engineers can accurately predict the material’s behavior and design components that can withstand the expected loads.

The primary aluminum ores are:

Bauxite: This is the most important ore of aluminum. Bauxite is a mixture of aluminum oxides and hydroxides, often with impurities like silica, iron oxides, and titanium dioxide. It is named after Les Baux, in France, where it was first discovered.

Cryolite (Na₃AlF₆): Historically significant for aluminum production, now mainly synthetic due to natural deposits being exhausted.

Alunite (KAl₃(SO₄)₂(OH)₆): This sulfate mineral can be a source of aluminum, though it's not as economically viable as bauxite.

Gibbsite: A form of aluminum hydroxide (Al(OH)₃), which is one component of bauxite.

Boehmite: Another aluminum hydroxide mineral (γ-AlO(OH)) found in bauxite.
Diaspore: An aluminum oxide hydroxide (α-AlO(OH)) that also occurs in bauxite.

C103 is attracting attention in various industries such as aerospace and energy for its excellent mechanical properties, but its use was limited due to its high price.
InssTek is researching powder recycling to reduce costs and broaden its industrial applications.

Powder
- The analysis of powder recycling results indicates that powders recovered in an argon environment can be reused in LP-DED process.
- However, prior to reuse, a sieving process is deemed essential.

LP-DEDed Specimen
- 3D printed specimens using recycled powder confirm that powders recovered and recycled in an argon atmosphere exhibit performance comparable to that of virgin powder, meeting ASTM standards and thereby validating their potential for reuse.
- Although recycling environment is important, test results show that printing environment is more critical factor affecting mechanical properties.

Hydrometallurgy involves the use of aqueous solutions for the recovery of metals from their ores or concentrates. Here are some key techniques used in hydrometallurgy:

1. Leaching
Acid Leaching: Sulfuric acid (H₂SO₄) or hydrochloric acid (HCl) is used to dissolve metals like copper, uranium, and zinc from their ores. For instance:
Heap Leaching: Used for low-grade ores, where the ore is piled up, and a leaching solution is sprayed over the heap, allowing the solution to percolate through and dissolve the metal.
In-Situ Leaching: Applied for uranium, where leaching solutions are injected into the ore body still in the ground, and the metal-bearing solution is pumped out.
Alkaline Leaching: Ammonia or sodium hydroxide might be used for metals like copper, nickel, or cobalt, especially when the ore contains valuable metals that would be degraded by acid.
Pressure Leaching: Conducted under high pressure and temperature to accelerate the leaching process, often used for refractory ores (e.g., the Sherritt-Gordon process for nickel).

2. Solvent Extraction (SX)
This technique is used to separate metals by their different solubilities in an organic solvent from an aqueous phase. It's particularly effective for copper, uranium, and rare earth elements. The metal ions transfer from the aqueous phase to the organic phase, which can then be stripped to recover the metal.

3. Ion Exchange
Involves passing the leachate through resins that selectively adsorb metal ions. It's useful for purifying solutions and concentrating metals like gold, silver, and uranium before further processing.

4. Precipitation
After leaching, metals can be precipitated out of solution by adding chemicals that form insoluble compounds with the desired metal. For example:
Hydroxide Precipitation: Used for metals like iron, where raising the pH forms metal hydroxides.
Sulfide Precipitation: Selective precipitation of metal sulfides, often used for copper, lead, and zinc.

5. Electrowinning
The recovery of metals from solution by electrolysis. The metal ions are reduced at the cathode to form pure metal. This is commonly used for copper, zinc, and nickel.

6. Cementation
A process where a more active metal (like iron) is used to precipitate a less active metal (like copper) from solution. This method was historically significant for copper recovery in the cementation process using scrap iron.

7. Membrane Processes
Including reverse osmosis or nanofiltration, these can be used for separating and concentrating metal ions or for purifying leach solutions.

8. Biohydrometallurgy
Leveraging microorganisms (bacteria, fungi) to leach metals from ores. This includes:
Bioleaching: Bacteria like Acidithiobacillus ferrooxidans can oxidize sulfides to release metals.
Biosorption: Using biomass to adsorb metals from solution.

Sometimes plastic deformation occurs without slip. Suggest mechanisms by which plastic deformation could occur without slip in the following circumstances:

a. At elevated temperature with a very low strain rate.
Diffusion creep, in which atoms diffuse through the lattice from regions under a compressive stress (with a raised chemical potential) to regions under a tensile stress (with a lowered chemical potential).

b. In an h.c.p. polycrystalline sample with only 3 independent slip systems.
By mechanical twinning, in which the packing sequence of the structure changes at a 'twinning plane' in order to accommodate the deformation.

c. In a semi-crystalline polymer sample.
Crystallites in polymer samples consist of folded polymer chains. Plastic deformation can occur by 'unfolding' of these chains to accommodate the strain, or by rearrangement of the amorphous material between the crystalline regions.

The Stainless Steel Family

The stainless steel family encompasses a diverse group of iron-based alloys, all characterized by their exceptional resistance to corrosion. This resistance stems from the presence of chromium, typically at a minimum of 10.5%, which forms a passive, self-healing oxide layer on the steel's surface when exposed to oxygen. This layer acts as a barrier, preventing further oxidation and protecting the underlying metal from rust and other forms of corrosion. Beyond chromium, other alloying elements like nickel, molybdenum, titanium, and niobium are often added to enhance specific properties such as strength, ductility, weldability, and resistance to high temperatures or specific corrosive environments. This versatility allows stainless steels to be tailored for a wide range of applications, from everyday cutlery and kitchen appliances to critical components in aerospace, medical, and chemical processing industries.

The ISO 5832-2 specification qualifies Unalloyed Titanium Grades for medical applications.

These specification grades are used in medical implant manufacturing because they have stringent microstructure requirements such as uniform alpha phase distribution, grain size, and no foreign phases (Alpha case), which can improve Unalloyed Titanium properties.

Because there are fewer grain boundaries with coarser grain sizes, the mobility of dislocations is not as restricted. As a result, the strength of Titanium implants with the coarser grain is less.

With fine grain size, there are a large number of grain boundaries that obstruct dislocation migration as we apply stresses to Titanium. As a result, it improves the strength of a Titanium implant.

If the grain size of Titanium materials is not uniform, there will be different properties at different locations, which is inappropriate for the long life of Titanium implants.

If the grain size of Titanium implants is uniform throughout the Titanium implant, it can have homogenous properties, and an implant can last longer in the human body.

That's why ISO 5832-2 states that the grain size of Titanium material used for medical applications should be uniform and with a grain size 5 or finer.

To explain the alpha case, we will make a separate post as it is a common requirement for all medical Titanium grades.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper.

Graphene

Graphene is a single layer of carbon atoms arranged in a honeycomb lattice structure, making it the thinnest known material at one atom thick. This two-dimensional material, derived from graphite, possesses an array of extraordinary properties:

1. Strength: Graphene is exceptionally strong, with an intrinsic tensile strength estimated to be over 100 times greater than steel while being incredibly lightweight.

2. Conductivity: It is an excellent conductor of both heat and electricity, with electron mobility exceeding that of silicon by a significant margin, making it promising for use in electronics.

3. Transparency: Despite its strength, graphene is nearly transparent, absorbing only about 2.3% of light, which makes it suitable for applications like transparent conductive films.

4. Flexibility: Due to its atomic thinness, graphene is highly flexible, capable of being bent, stretched, or even folded.

5. Impermeability: It is impermeable to gases and liquids, even to the smallest gas molecule, helium, which has potential applications in filtration and barrier technologies.

Graphene's discovery was first theorized in 1947 by Philip R. Wallace, but it wasn't until 2004 that it was physically isolated and characterized by Andre Geim and Konstantin Novoselov at the University of Manchester, earning them the Nobel Prize in Physics in 2010. The unique combination of properties makes graphene a candidate for numerous applications across various industries, including electronics, energy storage, sensors, and more. However, scaling up production while maintaining high quality remains a challenge for widespread commercial adoption.

How does X-ray diffraction (XRD) work?

XRD works by directing a beam of X-rays at a sample and observing the diffraction pattern that results from the constructive interference of scattered X-rays off the lattice planes. Bragg's Law (nλ = 2d sinθ) is used to determine the lattice spacing (d) from the diffraction angle (θ). This helps in identifying the crystal structure and phases present.
