图5 梯度纳米晶NiTi合金系统单程形状记忆过程中微结构演化的模拟结果(各图片与图4中选取的代表点对应).颜色条表示$\eta $ 的值, 即$\eta =0$, 1和$-1$分别表示奥氏体,$+$M和$-$M马氏体变体
Fig. 5 Simulated microstructure evolution obtained in the one-way shapememory process of the gradient nanocrystalline NiTi alloy system (picturescorrespond to the representative points selected in Fig. 4). The colorlegend denotes the value of $\eta $, where $\eta = 0$, 1 and $-1$ representthe austenite, $+$M and $-$M variants, respectively
