Investigation and modelling of the formation of the structure of the heat affected zone in low-alloy steels

Abstract

Mathematical models of the welding source of heat and supercooled austenite structural transformations, allowing for calculating structural and phase composition in the thermal action zones of the low-alloy steels welded joints accurately enough for the practical applications, are suggested.
