Interactions between martensitic NiTi shape memory alloy and Nb nanowires in composite wire during tensile deformation

This study investigated the interactions between martensitic NiTi shape memory alloy and Nb nanowires in composite wire during tensile loading by means of in-situ high-energy X-ray diffraction. have significant influence on transformation behavior, annealed texture, martensite variant reorientation behavior including texture evolution load transfer among variants matrix. Meanwhile, existence densely distributed increases internal stress matrix generated process, causes negative axial lattice stresses all unfavored after when is under stress. In addition, an exceptionally large elastic strain 4.7% was produced over deformation . heterogeneous distribution exists nanowires, it associated with • Interactions investigated. Nanowires inhibit twinning. induce variants. Inhomogeneous nanowires.
