摘　　要：在实验室及工业生产条件下研究加热工艺对含Nb汽车用微合金钢显微组织和力学性能的影响。用THERMECMASTOR Z型热模拟实验机、光学显微镜及电镜分析及测定该钢种在不同加热条件下的奥氏体组织状态及碳化物析出状态,为合理制定热加工工艺提供了理论依据。The effect of heating process on the microstructure and mechanical properties of Nb microalloyed automotive steels has been studied in laboratory and under the industrial process conditions. On a THERMECMASTORZ hot simulator, OM and TEM were employed to investigate the austenite microstructure refinement and the sizes and distribution of the precipitate particles.In this way,theoretical basis of heating process on the strip mill is provided.
