Abstract

NiTi shape memory alloys (SMAs) were utilized in electronics, medicine and aerospace, etc. One difficult point is the solid-state phase transformation of NiTi alloy during machining operations. Additive manufacturing offers a promising solution to this dilemma, which proves a new way for complex structure NiTi alloy. In this paper, we briefly introduce the research progress and status of additive manufacture (AM)-fabricated NiTi alloy at home and abroad. The phase transformation behavior was analyzed by varying AM parameters. Afterward, the previously reported superelasticity of as-built NiTi alloys in compressive and tensile stress states was summarized. The final section summarizes the main findings of tribological properties of NiTi alloys and outlines the trend for future work.
