研究了还原速率对冷轧Ti-26mol%Nb-3mol%Al形状记忆合金变形织构的影响。室温（RT）下合金为母相（β: bcc），马氏体起始温度远低于室温；冷轧后未检测到残余马氏体。还原率r在60 ~ 99%之间变化。织构演化过程如下：γ纤维{001}< 110 >{001}< 110 > +{112}< 110 >(α纤维)。{001}<110>的强度在r = 97%左右达到最大值。再结晶织构受还原速率控制；优化r有望获得{001}<110>的再结晶织构，这是超弹性变形的首选织构。
The effect of reduction rate on the deformation texture of cold-rolled Ti-26mol%Nb-3mol%Al shape memory alloy was investigated. The alloy is the parent phase (β: bcc) at room temperature (RT) and the martensite start temperature is much lower than RT; no residual martensite was detected after cold-rolling. The reduction rate, r, was varied in the range of 60 ~ 99%. Texture evolution was as following; γ-fiber à {001}<110> à {001}<110> + {112}<110> (α-fiber). The strength of {001}<110> was maximized at about r = 97%. The recrystallization texture is expected to be controlled by the reduction rate; optimization of r is supposed to be promising to obtain the {001}<110> recrystallization texture that is preferred for superelastic deformation.
