本文研究了在奥氏体(γ)-铁素体(α)两相区的轧制条件下,HSLA(高强度低合金)钢板强度和韧性的匹配;分析了与轧制条件有关的钢板显微组织变化情况。揭示出变形铁素体的数量主要受轧制温度限制,并通过压下量研究{100}织构。铁素体结构受两个轧制参数的影响。从显微组织的角度看,轧制参数和合金元素的作用是使强度和韧性最佳匹配。通过研究,确定了钢板的工业性生产。同时指出,在奥氏体区进行压下以形成细奥氏体晶粒的两相区轧制,使碳当量低的钢板具有极好的强度和韧性匹配。
In this paper, the matching of strength and toughness of HSLA (high strength and low alloy) steel under rolling conditions of austenite (γ) -ferrite (α) two-phase region was studied. Micro-organizational changes. It is revealed that the amount of deformed ferrite is mainly limited by the rolling temperature and the {100} texture is studied by reduction. The ferrite structure is affected by two rolling parameters. From the microstructure point of view, the effect of rolling parameters and alloying elements is to best match strength and toughness. Through research, to determine the industrial production of steel. It is also pointed out that rolling in the austenite region to form a two-phase zone of fine austenite grains enables the steel plate with a low carbon equivalent to have excellent strength and toughness matching.
