Abstract
Liquid metal induced embrittlement (LMIE) refers to the loss of ductility of normally ductile metals and alloys when stressed while in contact with a liquid metal. Various models have been proposed to describe the mechanisms by which LMIE failure takes place. In the present study the most promising of these are discussed in detail and analysed critically in the light of experimental results. The advantages and limitations of each are highlighted and, where possible, comparisons between the characteristics of each are presented. The diverse results obtained in previous investigations and the difficulties encountered in LMIE testing have resulted in numerous and often contradictory models.
