On the mechanism of texture transition in FCC metals

摘要: Polycrystalline copper sheets having orientations (112) [−1−1l] and (011)[−2−1l] were rolled successively at two temperatures. When the liquid nitrogen temperature, (112)[−1−1l] texture decreased mainly by mechanical twinning, it also extended its spread toward (111)[−1−12]. The resolved shear stress on slip systems, which produce lattice rotations from to (111)[−1−−12], is smaller than that systems giving rise inverse rotations. formation of minor component (111) planes parallel rolling plane in alloy type can be explained basis hardening latent systems. room orientation was gradually rotated (011)[−2−1l], but around has scarcely increased, sheet with (011)[−2−11] up 92 pct 100°C. These results indicate cross-slip does not contribute displacement (112)[−1−1l], retards In consequence, prime factor for transition ease rather cross-slip.
