Title: New methodology of testing phase transformations in structural steels in weldimg thermal cycle contditions
Author: M. LOMOZIK

Abstract: The paper presents differences in the character of the course of a thermal cycle in welding conditions compared with the cycle of a traditional heat treatment.
The author elaborates the methodology of testing austenite phase transformations in steels affected by welding thermal cycles; the said methodology has been developed and put in practice at Instytut Spawalnictwa in Gliwice. The results of related tests are presented in the form of CCT diagrams for welding conditions for the following grades of structural steels applied in power engineering sector: X10CrMoVNb9-1 (P91), X10CrWMoVNb9-2 (P92), X12CrCoWVNb12-2-2 (VM12-SHC), 7CrMoVTiB10-10 (P24) and 10CrMo9-10 (P22).


Keywords: phase transformations, welding thermal cycle, simulation, constructional steels
