Feasibility study of the production of biomedical Ti–6Al–4V alloy by powder metallurgy
چکیده انگلیسی


• The production of the biomedical Ti–6Al–4V alloy by powder metallurgy is assessed.
• The prealloyed and master alloy addition approaches are considered and compared.
• An in-depth study of the mechanical performances of the materials is carried out.
• The dynamic Young modulus of the alloys developed was determined.

Titanium and its alloys are characterized by an exceptional combination of properties like high strength, good corrosion resistance and biocompatibility which makes them suitable materials for biomedical prosthesis and devices. The wrought Ti–6Al–4V alloy is generally favored in comparison to other metallic biomaterials due to its relatively low elastic modulus and it has been long used to obtain products for biomedical applications. In this work an alternative route to fabricate biomedical implants made out of the Ti–6Al–4V alloy is investigated. Specifically, the feasibility of the conventional powder metallurgy route of cold uniaxial pressing and sintering is addressed by considering two types of powders (i.e. blended elemental and prealloyed). The characterization of physical properties, chemical analysis, mechanical behavior and microstructural analysis is carried out in-depth and the properties are correlated among them. On the base of the results found, the produced alloys are promising materials for biomedical applications as well as cheaper surgical devices and tools.
