Abstract

Fe-Cr-Ni alloys were arc-melted and GTA-welded at a nitrogen gas atmosphere with various conditions, in order to study effects of chromium and nickel on the nitrogen absorption of ternary iron alloy during arc-welding. The nitrogen content of arc-melted alloy decreased with an increase of arc-current, and the tendency was marked in high chromium and low nickel alloys. Nitrogen content diagrams in the ternary system of Fe-Cr-Ni where each alloy content is less than 30% were obtained by arc-melting and GTA-welding. The nitrogen absorption of Fe-Cr-Ni alloy during arc-welding was thermodynamically discussed comparing with arc-melting and equilibrium data at equivalent temperatures.
