使用超低碳钢在高应变率的大应变变形过程中观察到微观结构的演变。通过降低变形温度和提高应变速率获得细晶粒铁素体。开发出ND∥<100>、<111>、RD∥<110>等质地较强的产品。晶粒尺寸的变化可以通过Z参数来分析，而持续时间对高应变率变形时晶粒尺寸预测的偏差影响较大。
Microstructural evolution was observed during large strain deformation with a high strain rate using an ultralow carbon steel. Fine-grained ferrite was obtained by decreasing the deformation temperature and increasing the strain rate. A strong texture, such as ND∥〈100〉, 〈111〉 and RD∥〈110〉, was developed. The change of grain size could be analyzed by the Z parameter, whereas the duration had a large effect on the deviation of the predicted grain size in deformation with a high strain rate.
