摘　　要：在不同拉伸速度条件下,通过单向拉伸试验,研究了DP钢的屈服强度、抗拉强度与伸长率。分析了高强度DP钢的拉伸速度与塑性变形性能的关系。结果表明,DP钢的屈服强度不受拉伸速度的影响;随拉伸速度的增加,DP钢的抗拉强度增大,伸长率减小。The yield strength, tensile strength and elongation of DP steel were studied by uniaxial tension test under different tensile velocities. The relation between the tensile velocity and plastic deformation properties of DP steel was analyzed. The results indicate that the yield strength is not affected by tensile velocity. With the increase of tensile velocity, the tensile strength of DP steel increases, and then, the elongation decreases.
