Abstract
An analytical model is developed for the rate of supply of embrittler to the crack tip in liquid metal induced embrittlement (LMIE), assuming that crack propagation rate is controlled by viscous losses in the liquid metal. The results of the modelling are compared with experimentally determined data for crack propagation rates in LMIE. This study indicates that in several systems the LMIE crack propagation rate is not controlled by viscous losses in the crack and that a study of crack propagation rates in LMIE may yield useful insight into the micromechanisms of LMIE fracture.
