标准摘要
[中文适用范围]： 本文件描述了使用电子背散射衍射 (EBSD) 技术评估金属材料塑性和/或蠕变变形引起的机械损伤（例如疲劳和蠕变）的定向误差分析指南。 该国际标准定义了定向误差参数并指定了此类机械损伤评估的测量条件。 建议使用本文件来评估奥氏体不锈钢的机械损伤，奥氏体不锈钢广泛用于发电厂和其他设施的各种部件。 本文件中的机械损伤是指由于外部过载、疲劳、蠕变等原因导致结构材料断裂的损伤；化学和热损伤本身除外。 [外文原描述]： This document describes the guidelines for misorientation analysis to assess mechanical damage such as fatigue and creep induced by plastic and/or creep deformation for metallic materials by using electron backscatter diffraction (EBSD) technique. This international standard defines misorientation parameters and specifies measurement conditions for such mechanical damage assessment. This document is recommended to evaluate mechanical damage of austenitic stainless steel, which is widely used for various components of power plants and other facilities. In this document, the mechanical damage refers to the damage which causes the fracture of structural materials due to external overload, fatigue and creep; excepting the chemical and thermal damages themselves.
