基于不连续纤维强化的复合材料混合物定律,考虑到马氏体中含碳量(即马氏体的强度)以及马氏体相变引起铁素体的强化等因素对混合物定律中修正系数的影响,双相钢中的混合物定律可表示为用此公式对不同临界区温度处理后的双相钢的抗拉强度进行了计算,计算值与试验值比较一致。进一步阐明了双相钢的强化本质、有关各因素的交互作用与它们对强化作用的影响。
Based on the law of discontinuous fiber reinforced composites, the influence of factors such as the amount of carbon in martensite (ie, the strength of martensite) and the ferrite strengthening caused by martensitic transformation on the correction coefficient in the mixture law , The law of mixture in dual-phase steel can be expressed as the formula for calculating the tensile strength of the dual-phase steel after temperature treatment in different critical sections, the calculated values are consistent with the experimental values. Further clarify the strengthening of dual-phase steel essence, the interaction of the various factors and their impact on the strengthening effect.
