Abstract
The fine structure of low-carbon low-alloy pipe steel after controlled thermomechanical processing and subsequent austenitization at 980°C is studied in this work using scanning and transmission electron microscopy methods. The evolution of austenite decomposition products with an increase in the cooling rate from the austenitic region from 35 to 500 deg/s is described. The martensitic-austenitic component is revealed and identified in the structure of steel based on quasi-polygonal bainite.
