【摘要】 采用定量金相法分析计算了亚共析钢拉拔变形中先共析铁素体应变量。结果表明 ,拉拔变形初期先共析铁素体应变量增大趋势远高于珠光体应变量 ;当应变量达到一定程度ε≈ 1 0时 ,两者同步增长 ,但最终先共析铁素体应变量仍远大于珠光体应变量更多还原

【Abstract】 The strain of the proeutectoid ferrite in hypoeutectoid steel drawing was measured and analyzed by quantitative metallography.The results show that strain of the proeutectoid ferrite increases faster than that of pearlite at the beginning of deformation.When the drawing strain reaches to about 1.0,the increasing of the strain of both the proeutectoid ferrite and pearlite is synchronous.But eventually the strain of the proeutectoid ferrite is still larger than that of pearlite.更多还原
