文摘

Inconel 625 with 0.4 wt% boron modification was made on stainless steels 304 using gas tungsten arc deposition process. Much more eutectics were observed in IN625B than conventional IN625 during gas tungsten arc deposition. Calculated re-melting boundary was correlated well with hardness profile and observed microstructure evolution. Segregation patterns of major alloying elements followed Clyne-Kurz model during deposition solidification.
