Influence of Mo Content on the Microstructure and Mechanical Properties of Ti6AlxMo Alloy

Abstract

Now a days, extensive research has been attracted by the α + β based Ti alloys in biomedical applications due to their low elastic modulus and high strength properties. In order to explore the performance of Ti6AlxMo based alloys, Ti6Al with different amount of Mo-based samples were fabricated by powder metallurgy technique. The mechanical properties of the samples such as elastic energy, total energy and elastic recovery were studied through nanoindentation tests. Designed alloys exhibit elastic recovery values in the range of 25.4% - 33.7% which is higher than commonly used biomaterial such as CP Ti therefore it has good impact resistance properties. Ti6Al15Mo alloy with dominant β phase microstructure shows a high elastic energy as well as elastic recovery values which makes it more advantageous than CP Ti for load bearing implant applications.
