In order to address the challenges in fabrication NiTiNb ternary alloy structures, researchers from Shandong University (SDU) have proposed an alloy design strategy to prepare NiTiNb shape memory alloys (SMAs) through laser powder bed fusion in-situ alloying and post-heat treatment. The in-situ alloyed NiTiNb alloy shows typical transformation characteristics (e.g. wide hysteresis) and good mechanical/functional properties.
