WebMicrostructure. In many deformed or processed materials, the 3D orientation of the crystal lattices in the different grains is not random. The nature and degree of any alignment of these lattice orientations is known in materials science as “texture” (or in the geological sciences as “crystallographic preferred orientation”). WebDec 6, 2024 · In this study, the grain boundary sliding mechanism dominated creep process is taken into consideration during the stress relaxation test. At each stress drop cycle, the strain rate is continuously decreasing and over the range of 1 × 10 −8 s −1 to 1 × 10 −4 s −1. Overall, the strain rate during stress relaxation is really low.
