Effect of Thermal Action on Low-Carbon and Silicon-Manganese Steel Microstructure and Properties

Abstract

The change in microstructure is considered for silicon-manganese and low-carbon steels under conditions modeling prolonged thermal action. Metal structure and property degradation is revealed. It is shown that prolonged thermal action creates conditions for the occurrence of thermal deformation ageing, the initial stage of recrystallization, and also pearlite spheroidization.
