Abstract

Increasing of demand for implant material especially for hip bone is caused by the increasing of elder who are prone to osteoporosis. Several studies have reported that elements of Al and V in Ti-6Al-4V can decompose and result in adverse effects in the form of health problems, allergies, neurological disorders and Alzheimer's disease. In addition, Ti- 6Al-4V has a problem, the difference of young's modulus with human bones can cause stress shielding phenomena. The cost of replacing hip bones is quite expensive because it uses valuable alloy elements. The novelty carried out in this study was the design of a new titanium type β (beta) composition with a composition of the weight of Ti-6%Nb-6%Mo with the addition of Mn 8%, 10%, 12% and continued with heat treatment at 1100°C with variations of heat treatment time 3 hours, 6 hours and 12 hours with water quench which aims to increase beta phase volume. The material characterization was performed using XRF, XRD, metallographic test, micro Vickers hardness test and ultrasonic test to calculate the magnitude of young's modulus. The results obtained show that the addition of manganese will increase beta phase. The most optimal duration for heat treatment is 6 hours because the Ti-6Mo-6Nb microstructure with the addition of 12% manganese and heat treatment for 6 hours has higher beta phase volume than others.
