Study of the BS Temperature in a Molybdenum-Containing Ultra-Low Carbon Bainitic Steel for Heavy Plate Applications

摘要

The bainite transformation start temperature BS, has been studied in a series of modified ultra low-carbon bainitic (ULCB) steels. The influence of variables such as composition, thermomechanical processing, cooling rate and reheating temperature has been assessed in terms of their respective effects on the BS temperature of ULCB steels. The results of this study have shown that the BS temperature is strongly influenced by both the microstructural state of the austenite and the cooling rate for a given set of compositions and thermomechanical processes.
