摘要
The formation of cold rolling textures in FeCo, CuZn and Fe 3Al based alloys with B2 structure was analyzed using X ray diffraction technology. The difference of deformation textures obviously demonstrated the different behaviors of plastic deformation in the alloys. The boundary energy of anti phase domains has important influence on the crystallographic behaviors of B2 ordered alloys during deformation. The activation of slip systems on the ｛110｝ planes should be the main deformation mechanism in B2 ordered alloys. The mechanical twinning on ｛112｝ planes appeared frequently in CuZn alloy with lower boundary energy of anti phase domains, while a rather typical rolling texture like that in BCC metals was observed in Fe 3Al alloy with incomplete B2 structure, indicating that its boundary energy of anti phase domains does not have important influence on the deformation mechanism similar to BCC metals.
