A Ti-48Al-2Cr-2Nb alloy with uniformly dispersed nano-Y 2 O 3 addition was prepared by selective electron beam melting (SEBM). The effects of beam speed on the defects, microstructure and compressive properties were studied systematically. The Y 2 O 3 morphology gathered and exhibited a feathery...
