采用速率敏感晶体塑性理论，预测了面心立方金属板材单轴拉伸过程中主要理想取向的稳定性。结果表明，相对于拉伸坐标系而言，稳定性较好的理想取向，主要包括稳定取向Ｇ｛１１０｝〈００１〉Ｔ和亚稳取向Ｂ｛１１０｝〈１１２〉Ｔ与Ｓ｛１２３｝〈６３４〉Ｔ，以及在不同初始塑性应变比（Ｒ值）条件下可能成为稳定或亚稳取向的Ｃｕ｛１１２｝〈１１１〉Ｔ与Ｐ｛１１０｝〈１１１〉Ｔ和Ｃ｛１００｝〈００１〉Ｔ。取向ＲＧ｛１１０｝〈１１０〉Ｔ和ＲＣｕ｛１１２｝〈１１０〉Ｔ的稳定性较差。理想取向所对应的织构组分的稳定性与之相似
The rate-sensitive plasticity theory is used to predict the stability of the principal ideal orientation of the face-centered cubic metal sheet under uniaxial tension. The results show that the ideal orientation with good stability relative to the stretched coordinate system mainly includes the stable orientation G {110} <001> T and the metastable orientation B {110} <112> T and S {123} < 634> T and Cu {112} <111> T and P {110} <111> T and C {100} <001> that may become stable or metastable at different initial plastic strain ratios (R values) T. The orientations RG {110} <110> T and RCu {112} <110> T are less stable. The stability of the texture component corresponding to the ideal orientation is similar
