Abstract

The mechanism of crack apparition of an as cast high strength low alloy steel ingot was investigated. Elemental, mechanical and crystallographic analyses proved that tensile stresses accumulated during casting and annealing are responsible of crack generation. The crack propagation is favored by the formation of chromium carbides at prior aus-tenite grain boundaries.
