초록
Studies on tile microstructural and compositional changes in sensitized Ni base Alloy 600 by laser surface melting have been carried out using TEM equipped with EDXA. The microstructure of the laser melted zone was mainly consisted of fine cells, and along the cell and grain boundaries, Cr enrichment due to its segregation was observed. Cr carbides having formed along the grain bundaries during the sensitization treatment have been completely dissloved. The cell walls were decorated with dislocations and the very tiny precipitates, found to be Ti(CN) type, were distributed randomly along the cell walls with tangled dislocations around them.
