摘要: 利用Gleeble-1500D热模拟试验机将冷却速度控制在50 ℃/s,探究该冷速下WB36CN1钢的连续冷却转变产物。结果表明,WB36CN1钢由900 ℃连续冷却至室温后的基体组织包括少量针状铁素体、贝氏体铁素体、马氏体、块状铁素体及分布于马氏体板条界的膜状残留奥氏体,析出相包括棒状渗碳体(θ-碳化物)和与基体呈完全共格关系的球状NbC颗粒。

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
