拉伸凸缘性优良的高强度热轧钢板［日］木下正行１绪言热轧钢板用于制作底盘和车轮等汽车行走部件。近几年来由于人们对地球环境问题的关心日益增加，从而要求进一步降低汽车的燃料消耗量。为此，对利用高强度热轧钢板减轻车体重量的试验进行了认真的研究。尤其是板厚较厚... High-tensile hot-rolled steel sheets with excellent flange formability [J] Underworthy 1 INTRODUCTION Hot-rolled steel sheets are used for the production of chassis components, wheels and other automotive components. In recent years, increasing concern for the global environment has led to a demand for further reductions in vehicle fuel consumption. To this end, the use of high-strength hot-rolled steel plate to reduce the body weight of the test conducted a serious study. In particular, thicker plate thickness ...
