图6 NiTi-Nb复合材料在6次加载过程中的应力-应变曲线，以及在加载过程中NiTi马氏体峰面积随宏观应变的演变曲线

Fig.6 Stress-strain curves of the as-annealed NiTi-Nb composite, and the corresponding B19'-NiTi(001) peak area curves in the 6 loading processes (In each loading process, the “first yield point” on the stress-strain curve just corresponds to the “turning point” on the evolution curve of B19' peak areas, as marked by each dash line)
