Exploiting the superior mechanical properties of embedded nanowires in composites has proven to be challenging. Until recently, it is found that the ultra-large elastic strain of Nb nanowires can be exploited in a phase transforming NiTi matrix. We herein found that the elastic strain limit of embedded nanowires strongly depents on the heat treatment temperature of the Nb nanowires-NiTi composite. In this study, the effect of heat treatment temperature on the elastic strain limit of the nanowires embedded in the transforming NiTi matrix was studied by in-situ high energy XRD. It is found that the Nb nanowires gradually transformed into nanorods with increasing treatment temperature from 350℃ to 700℃, and accordingly the elastic strain limit of nanowires decreased from 6.1% to 2.6%. It is revealed the relationship between the elastic strain limit of nanowires and the treatment temperature of composite.
