综述了材料的液态金属脆化（LME）和固态金属诱发脆化（SMIE）现象，强调了与失效分析和预防相关的脆化的金相学、断口学和其他特征。结构金属/金属环境组合，其中有潜在的失败风险，影响脆化敏感性的变量，和脆化金属的来源进行了概述。然后讨论了脆化的机理和动力学，包括SMIE的最新数据，这些数据表明，在相同的同源温度T/Tm下，不同材料和脆化元素的开裂速率通常是相同的，其中T是脆化元素的熔化温度（K）。
The phenomena of liquid-metal embrittlement (LME) and solid-metal-induced embrittlement (SMIE) of materials are reviewed, emphasizing metallographic, fractographic, and other characteristics of embrittlement that are relevant to failure analysis and prevention. Structural-metal/metal-environment combinations for which there are potential risks of failure, variables affecting susceptibility to embrittlement, and sources of embrittling metals are outlined. The mechanisms and kinetics of embrittlement are then disucssed—including recent data for SMIE that show that rates of cracking are often the same for different materials and embrittling elements at the same homologous temperatures, T/Tm, where Tmis the melting temperature (K) of the embrittling element.
