Original subscribers to Sirius and XM have been disappointed because the title change, and others
Liquid metal embrittlement it. The practical significance of liquid metal embrittlement is revealed by the observation that several steels experience ductility losses and cracking during hot-dip galvanizing or during subsequent fabrication. Cracking can occur catastrophically and very high crack growth rates have been measured. Similar metal embrittlement effects can be observed even in the solid state, when one of the metals is brought close to its melting point; e.g. cadmium-coated parts operating at high temperature. This phenomenon is known as solid metal embrittlement. Liquid metal embrittlement or LME is characterized by the reduction in the threshold stress intensity, true fracture stress or in
