摘要
自Orowan提出用X射线衍射方法分析断口以来,已取得了很大的进展。用X射线分析断口,可获得断口上X射线有效穿透深度范围内的各种衍射信息,包括结构、形态、物理状态和力学状态等方面,但不直观。
Various information about fracture section of cyclic loading, impact loading and unidirectional loading in limits of effective penetrated depth was obtained by X-ray method. Analysis is made on deformation and mechanical behaviour in plastic zone of fracture section. A method of measuring depth of plastic zone without destruction is proposed also.
