Machine-learning optimization of microstructure and mechanical properties in 3D-printed W-alloyed refractory high-entropy alloys
Preparation of fine-grain, low-microsegregation Ti-rich refractory high-entropy alloys (RHEAs) remains challenging for conventional techniques. Additive manufacturing (AM)/3D printing can weaken the microsegregation but its strong directional heat flux is unfavorable to formation of fine equiaxed grains. Refining grain...
