Figure 2. Mechanical properties of in-situ Nb nanowires - oriented martensitic NiTi matrix composite wire.

(a), Comparison of tensile stress-strain curves of the composite wire (red curve) and a commercial superelastic NiTi wire (yellow curve). The black dotted line is a standard straight line. (b), Repeated cyclic tensile stress-strain curves of the composite wire. Inset is the enlarged view of the tensile cyclic curve.
