Conclusions
- 1.
Carbon increases the stability of the austenite in the transition zone; in welded samples of base metal containing 0.01 and 0.18% C the austenite in the base metal decomposes with formation of a structure corresponding to that resulting from quenching.
- 2.
Carbides are formed from austenite and alloyed martensite in the transition zone during isothermal heating at temperatures ensuring high diffusional mobility of carbon atoms and carbide-forming elements. The precipitation of carbon from the austenite and martensite lattices during crystallization of the carbide phase favors pearlitic and intermediate transformation of these phases.
