金相分析（Metallographic Analysis）是材料科学中用于研究金属或合金微观结构的关键技术，通过观察材料内部晶粒、相组成、缺陷分布等特征，评估其物理性能和加工历史。该技术广泛应用于航空航天、汽车制造、机械工程等领域，为材料质量控制、失效分析及工艺优化提供依据。
核心步骤包括：
典型应用中，金相分析可揭示热处理效果（如淬火后马氏体形态）、焊接缺陷（如气孔、裂纹）以及疲劳断裂机制。例如，航空发动机叶片通过该技术检测高温合金的蠕变孔洞，以预测使用寿命（来源：Springer Materials数据库）。
权威机构如美国材料与试验协会（ASTM）制定了相关标准（如ASTM E407-07），规范了不同金属的制样与腐蚀流程，确保分析结果的可重复性。
