金属板中的织构实用金属大多为多晶状态,即一块金属由很多细小的单晶晶粒所组成,每一晶粒的晶体取向各不相同。若这些取向呈统计分布,各方向的取向几率相同,则我们称这种状态的金属是无织构的,在宏观上表现为各向同性;反之,若各晶粒的取向呈现一定规律,即某些取向 The texture of the metal plate is mostly polycrystalline textured metals, that is, a piece of metal is composed of many small single crystal grains, each crystal grain orientation varies. If these orientations are statistically distributed and the probability of orientation in each direction is the same, then we call this state of the metal is non-textured, macroscopically isotropic; on the contrary, if the orientation of each grain presents a certain law, namely Some orientation
