Material properties mapping using complementary methods in titanium alloys TiMoSi used in medical application

摘要

Biocompatibility of medical implants is a long-sought goal of the physical sciences and medical research communities. This concept refers to a material's capacity to induce a response adequate to a bone host. However, identifying materials which are fulfilling this requirement for a wide range of different applications is still an unresolved issue. In this paper, are analyzed the properties of TiMo_(20)Si_xZr_7Ta_(15) alloys with different ratios of Si (x=0; 0.5; 0.75;1.0) with possibilities of use for medical applications, using a set of complementary testing methods based on X-ray diffraction, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy and resonant ultrasound spectroscopy (RUS). Across the compositions, the methods emphasize the mechanical properties of the sample, their microstructural characteristics, hardness and mechano-elastic properties, in order to establish a correlation between the structural parameters and mechanical properties of the sample, which are crucial in the understanding the feasibility of incorporating these alloys into prosthetics.
