Abstract
The effect of K418 and 42CrMo dissimilar metal laser welding velocity, temperature of post-weld heat treatment on controlling formation of laves phase were investigated. Microstructure and laves phase were characterized by optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).Results showed that Laves phase formed in the interdendritic regions of the weld metals as a result of segregation. The morphology and composition of Laves phase depended strongly on heat input/cooling rate and influenced its response to subsequent homogenization post-weld heat treatment.
