Microstructural refinement and enhanced mechanical properties of suction-cast NiTi-Al alloy for structural use
文献摘要：
A significant refinement of the microstructure of structural NiTi alloy was achieved through a combina-tion of Al addition and fabrication by suction casting.This is attributed to the change from a layer-by-layer to volume solidification mode with Al content increasing,which causes a change in grain shape from columnar to equiaxed.Furthermore,when compared with conventional casting,suction casting optimizes the microstructure of the alloy by refining the grain size and ensuring a homogeneous dis-tribution of Ti2Ni and Ni2TiAl phases.The high cooling rate of suction casting also delays the formation of p'-Ni2TiAl phase.Finally,this fine microstructure and uni-form distribution of intermetallic phases result in the ulti-mate compressive strength of up to 2463.7 MPa,representing an improvement of 370 MPa over conven-tionally cast NiTi-Al alloy.
