摘　　要：运用gleeble-1500热模拟试验机November对含硼微合金钢进行了单、双道次压缩模拟,并通过非线性回归分析得到了静态与动态软化百分比(X)与变形温度(T)、变形程度(ε)、变形速率(ε·)、原始晶粒尺寸(d0)、道次间隔时间(t)之间的关系。The compress during single and double passes for boron microalloyed steel was simulated using a gleeble-1500 thermal simulation testing apparatus, The quantitative effect of deformation temperature(T)、deformation degree(ε)、deformation rate(ε·)、primary grain size(d_0)、and interval time between passes(t)on static state and dynamic softening fraction(X)was obtained by nonlinear regression analysis.

关 键 词：含硼微合金钢 静态软化 动态软化
