摘　　要：本文采用试样熔化凝固法研究了含铌低碳低合金钢的热塑性,并在此基础上分析了铌的影响。用扫描电镜研究了不同试验条件下试样的断口,提出了低塑性产生的原因及其断裂方式。The hot ductility of Nb-bearing low carbon, low alloy steels was investigated on a Gle-eble-1500 machine by using in situ melting and solidification method. The effect of Nb on hot ductility was analysed. The fracture surfaces were studied by means of SEM. The causes of low ductility and its fracture mode have been identified.
