Metallurgical Engineering

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.

By following this structure and being aware of what to expect, you can create a compelling research proposal that effectively communicates your planned study.

In the case of medical applications, stringent user specifications require controlled microstructures and freedom from melt imperfections. The interstitial elements of iron and oxygen are melt imperfections that are carefully controlled while manufacturing Titanium alloy to improve ductility, fracture toughness, and fatigue strength. Controlled interstitial element levels are designated ELI (extra low interstitials).


We have a huge inventory of Titanium Extra Low Interstitial (Ti6Al4V ELI) grade round bars and sheets, according to ASTM F136 & ISO 5832-3 standards for medical applications.

Oxygen is a predominant interstitial impurity, widely adopted in titanium-based alloys to enable a potent strengthening effect for diverse applications. Titanium is also inherently expensive due to the tight control of interstitial impurities during its manufacturing process.

Oxygen has a deleterious effect on ductility, fracture toughness, and fatigue strength of titanium.

If your application requires high fracture toughness and fatigue strength, we have such titanium material in stock.

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.
