摘要
本文研究了低碳合金钢先共析铁素体+粒状贝氏体混合组织与单一粒状贝氏体组织的性能,先共析铁素体的存在降低钢的机械性能,尤其是显著降低冲击韧性。
This paper deals with the mechanical properties of mixed hypoeutetic ferrite+granular bainite structures and that of pure granular bainite structure, the existence of hypoeutectic ferrite reduces the mechanical properties of the steels, especially brings low impact toughness significantly.
