“…The biocompatibility property is superior to that of the alloy featuring V. The Ti-6Al-7Nb alloy's toughness, abrasion resistance, and adhesion properties are all improved by adding Nb in place of V. On contrast to Ti-6Al-4 V alloy, Ti-6Al-7Nb alloys have an elongation that is roughly 40% greater. The hardness and low friction coefficient of the formed Nb 2 O 5 oxide layer on the Ti-6Al-7 Nb surface are necessary for an increase in wear properties [41,42]. Indium (In) can be utilized as an alloying constituent in biomaterials to procure desirable performance.…”

Implants play a vital role in a person's life because losing any body part to function less actively, which makes the sufferer uncomfortable. Implants should be both biocompatible and non-toxic to the body is essential to achieve its biocompatibility nature. To create orthopaedic, dental, and surgical implants, biomaterials were divided into three categories: metallic, polymeric, and ceramic. Materials based on polymers indicate their degree of adaptability in terms of sutures, medication delivery, etc. Ceramic materials are known for their high compressive strength and inert behaviour, which combine aesthetic qualities. Metallic biomaterials are enhanced by their high strength and resistance to fracture. One of the most promising techniques for improving a material's mechanical qualities is powder metallurgy. Powder metallurgy involves blending of powders, compaction of blended powder, sintering and mechanical test. Samples with varying compact pressures, sintering temperatures, and sintering times were created using the powder metallurgy process. The aim of the research work is to get the concept of powder metallurgy, biomaterials commercially available for orthopaedic and dental applications, properties of biomaterial and methods to fabricate the material effectively.

This study focused on developing microstructural, thermal, and radiation shielding changes in Al50Si25B25 powders using mechanical alloying techniques. Based on the x‐ray powder diffraction data, the crystallite size and microstrain of the 100‐hours milled powder were calculated as 0.25 nm and 50.33 %, respectively. The solubility of silicon in the α‐aluminium matrix increased with longer mechanical alloying duration. Transmission electron microscope analyses further showed that the alloy particulates had an average size of 3 μm and an average grain size of 0.226 nm. The radiation shielding properties of the Al50Si25B25 powders indicated that the Linear Attenuation Coefficient value increased from 0.0554±0.1689 cm−1 to 1.0632±0.2425 cm−1 with an increase in the thickness of the Al50Si25B25 alloy. This work successfully demonstrated the potential of mechanical alloying techniques to enhance the microstructural and thermal properties of Al50Si25B25 powders. It highlighted their effectiveness in providing radiation shielding capabilities when varying the thickness of the alloy.
