The Influence of Heat Treatment on the Microstructure and Hardness Properties of Ti6Al4V and MgAZ91D Alloys / Yusliza Yusuf...[et al.]

Ti6Al4V alloy and MgAZ91D alloy have excellent combinatorial properties. However, in many cases their applications are limited because of weaknesses in their mechanical properties such as low fatigue strength for MgAZ91D and low modulus elasticity for Ti6Al4V. In this work, the proposed solution is...
