Description
Summary:The effect of iron addition on microstructure and mechanical properties of Ti-6Mo-4Cr system were investigated in this work. The alloy was produced by a vacuum arc melting furnace under ultra-high purity argon atmosphere. X-ray diffraction (XRD) was conducted for phase analysis. The as-cast microstructure was observed by Optical Microscope (OM). The microhardness test and impulse excitation examination were performed to evaluate the hardness and elastic modulus of the alloy. The β phase titanium was formed in 1 and 2 wt.% iron addition. The optimum hardness value was 500 HV (without iron addition) due to the presence of α phase titanium. The lowest elastic modulus was 88 with 2 wt.% iron addition due to the decrease of α phase titanium. The T6Mo-4Cr-2Fe seems to be a promising candidate for biomedical application.
