在假定4个{111}平面上的12个<110>切变体系上,面心立方金属轧制织构的形成,应用了最小切变量原理。首先,在充分制约冷轧的条件下,泰勒的5个切变模型显著再现了紫铜型泰勒方位{4、 4、11}、<11、11、8>,它是从S方位转变中获得的,如S1({123}<634>)→S2({124{<211 >)→S3({124}<865>)→S4({237}<654>)→泰勒方位。在这种情况下仍保留有一定量的黄铜方位{110}<112>。其次,满足塑性屈服凸面条件的6或8切变,既按照Bishop和Hill理论,再现了黄铜型方位{110}<112>,同时几乎没有泰勒方位。
On the assumption that 12 <110> shear systems on four {111} planes, the face-centered cubic metal rolling texture is formed using the principle of minimum shear. First, Taylor’s five shear models significantly reproduce the copper-type Taylor positions {4, 4, 11}, <11, 11, 8>, obtained from the S-orientation transition under conditions of sufficient constraints on cold rolling Such as S1 ({123} <634>) → S2 ({124 {<211>) → S3 ({124} <865>) → S4 ({237} <654>) → Taylor orientation. In this case, a certain amount of brass orientation {110} <112> remains. Second, a 6 or 8 shear that satisfies plastic yielding convex conditions reproduces both the brass orientation {110} <112> and the near-zero Taylor orientation, both according to the Bishop and Hill theory.
