Abstract
Intergranular Zn-assisted liquid metal embrittlement (LME) cracks have been frequently reported in steels, involving austenite grain boundary penetration of liquid Zn at high temperature. In the present study, a Zn-coated high strength steel was deformed at an intercritical temperature; and the characteristics of LME cracking were studied in a mixed microstructure composed of ferrite and austenite at the deformation temperature. Crack propagation was intergranular in austenite; in contrast, the ferrite exhibited both intergranular LME and "transgranular" LME. Trace analysis of the crack orientation was consistent with cracking along 100} cleavage planes.Citation
