Abstract

Phase transformations in laser-processed Fe-0.2%C-Cr surface alloys with 5%, 10%, 20%, and 30%Cr were studied by light and electron microscopy.Alloys containing 5% and 10%Cr were found to be fully martensitic with a dislocated lath type substructure. Thin films of retained austenite and a homogeneous dispersion of fine carbides were observed at the lath boundaries and prior austenite grain boundaries. The alloy with a 20%Cr content showed a unique microstructure of twinnedaustenite needles in a dislocated ferrite matrix while the alloy containing 30%Cr exhibited a dislocated ferrite structure with M23C6 carbides.
