Liquid Metal Embrittlement

Liquid Metal Embrittlement (LME) is a phenomenon where certain metals become fragile and crack when exposed to a specific liquid metal, often at high temperatures or stress. The liquid metal seeps into the tiny cracks or grain boundaries within the metal’s structure, weakening its internal bonds. This process can occur suddenly and without obvious warning, compromising the metal’s strength and integrity. LME is a concern in industries like aerospace and nuclear power, where materials often encounter liquid metals such as mercury or molten aluminum, posing safety risks and demanding careful material selection and control.
