金属疲劳破坏的研究是通过应用X射线衍射的精确方法，系统地研究在各种试验条件下晶体结构的变化来进行的。用于实验的材料是正火软钢（0 × 1%C）。疲劳试验有三种不同类型，分别涉及（a）反向扭转应力循环，（B）反向直接应力循环，和（c）交替直接应力循环，其中循环的上级应力保持在超过材料静态屈服点的恒定拉伸应力值。此外，还对施加不同强度的静态拉伸和静态扭转应力（包括导致断裂的应力）所引起的结构变化进行了比较观察。
The failure of metals by fatigue has been investigated by applying precise methods of X-ray diffraction to a systematic study of the changes produced in the crystalline structure under various conditions of test. The material used for the experiments was a normalized mild steel (0*1% C). The fatigue tests were of three distinct types involving, respectively, ( a ) cycles of reversed torsional stressed, ( b ) cycles of reversed direct stresses, and ( c ) cycles of alternating direct stresses where the superior stress of the cycle was maintained at a constant value of tensile stress exceeding the static yield point of the material. In addition, comparable observations have been made of the changes in structure arising from the application of static tensile and static torsional stresses of various intensities including those causing fracture.
