研究了低层错能奥氏体TWIP钢的冷轧组织和织构的演变。随着应变的增加,孪晶变形机制被激活。TEM、XRD等观察结果显示:随着应变量的增加,孪晶增加。在不同应变水平上,G{011}<100>织构都占主要位置。变形初始时,B{011}<211>织构强度较低,随着应变增加其强度显著增加。而E{111}<011>、Y{111}<112>、RG{011}<011>、Cu{112}<111>、CuT{552}<115>等织构在不同应变水平呈不同变化趋势。与其他织构相比,Cube{001}<100>织构强度相当低。
The evolution of the cold-rolled microstructure and texture of low-level-energy-lossable austenitic TWIP steels was investigated. As the strain increases, the twin deformation mechanism is activated. TEM, XRD and other observations show that: with the increase of strain, twins increase. At different strain levels, the G {011} <100> texture predominated. At the beginning of deformation, B {011} <211> has lower texture strength and its strength increases significantly with strain. The texture of E {111} <011>, Y {111} <112>, RG {011} <011>, Cu {112} <111> and CuT {552} <115> varied at different strain levels trend. Cube {001} <100> texture strength is quite low compared to other textures.
