Liquid Metal Cracking (LMC)

Definition - What does Liquid Metal Cracking (LMC) mean?

Liquid metal cracking (LMC) is the progressive reduction in ductility of metals or alloys that are typically very ductile, which occurs after they are stressed via contact with a liquid metal.

Liquid metal cracking is also known as liquid metal embrittlement (LME).

Corrosionpedia explains Liquid Metal Cracking (LMC)

Liquid metal cracking is caused when two primary conditions are met on a solid metal's surface when it comes into contact with a liquid metal:

  1. Low combined solubility between the contacted system
  2. Lack of reactivity between the two metals to form a chemically stable bond
