Phase transformation and deformation behavior of NiTi-Nb eutectic joined NiTi wires [PDF]

Scientific Reports, 2016
AbstractNiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests.
