Crystal Rotations under Conditions of Imposed Strain and the Influence of Twinning and Cross-Slip

摘要: Abstract Slip rotations in cubic crystals under conditions of imposed strain are not, general, uniquely determined, since several equivalent sets slip systems available to produce the particular shape change. However, it is shown that for certain crystal orientations undergoing deformation by rolling only four required operate and these cases determined unambiguously. Two orientation ranges, those having 〈110〉 〈111〉 transverse directions, considered rate rotation as a function orientation. It types {1110}〈112〉, {110}〈001〉, near-{4,4,11}〈11,11,8〉 stable f.c.c. {112}〈110〉, {001}〈110〉, near-{11,11,8}〈4,4,11〉 b.c.c. crystals.
