Optimal Design of High-Strength Ti‒Al‒V‒Zr Alloys through a Combinatorial Approach

Abstract: The influence of various Zr contents (0–45 wt.%) on the microstructure and mechanical properties of Ti6Al4V alloy was investigated through a combinatorial approach. The diffusion multiples of Ti6Al4V–Ti6Al4V20Fe–Ti6Al4V20Cr–Ti6Al4V20Mo–Ti6Al4V45Zr were manufactured and diffusion-annealed to obtain a large composition space. Scanning electron microscopy, electron probe micro-analysis, and a microhardness system were combined to determine the relationships among the composition, microstructure, and hardness of t… Show more

“…The differences in the surface roughness values between different materials might be explained by differences in stiffness and hardness of the materials [ 25 , 26 , 27 ]. Ti and CoCr showed the highest surface roughness values and also deeper scratches on the surface after the curette and ultrasonic scaling.…”

“…Finally, CALPHAD methods are both computationally efficient and have sufficiently large databases to produce accurate predictions for many HEA compositions [147,148] . In fact, CALPHAD methods are able to screen more compositions than any of the other computational methods (up to 10 6 compositions) in a reasonable time span [135] .…”

“…Database mining was first introduced in materials science to predict stable compositions, or estimate material properties from composition. Database mining has been successfully implemented to predict stable crystal structures [209][210][211] and predict material properties as a function of composition [212][213][214][215][216]. Some specially designed search algorithms have also been designed for improved speed in automated searches [217].…”
