标准摘要
[中文适用范围]： “有效颗粒或域尺寸”是X射线衍射文献中使用的短语，用于描述衍射材料内相干区域的尺寸。从这个意义上说，相干性意味着作为一个整体进行衍射。小颗粒尺寸会导致 X 射线谱线变宽，因此可以进行测量。它已被证明与透射电子显微镜中观察到的子结构有关。颗粒尺寸受硬化、冷加工和疲劳的影响；相反，越来越多的证据表明，颗粒尺寸本身会影响静态和动态强度。 [外文原描述]： "Effective particle or domain size" is a phrase used in X-ray diffraction literature to describe the size of the coherent regions within a material which are diffracting. Coherency in this sense means diffracting as a unit. Small particle size causes X-ray line broadening and as such can be measured. It has been shown related to substructure as observed in transmission electron microscopy. Particle size is affected by hardening, cold working, and fatigue; conversely, there is increasing evidence that particle size, per se, affects both static and dynamic strength.Cross Reference:
