Abstract: Continuous cooling transformation products of WB36CN1 steel at the cooling rate of 50 ℃/s were investigated by using Gleeble thermal simulation testing machine. The results show that after continuous cooling from 900 ℃ to room temerature, the matrix of WB36CN1 steel includes a small amount of acicular ferrite, bainite ferrite, martensite, massive ferrite and membranous retained austenite distributed at the martensite lath boundary, and the precipitates include rod-like cementite (θ-carbide) and spherical NbC particles which are completely coherent with the matrix.

Key words: WB36CN1 steel, continuous cooling transformation, acicular ferrite, bainitic ferrite, martensite
