汽车板的冶金技术与汽车制造技术及数量发展关系极为密切，从近４０年日本主要钢铁制造技术的发展可明显看出这一点，见图１［１］。过去大量的研究工作已基本摸清钢板的成分、组织与性能间的内在联系。于是，通过不断采用先进的工艺控制技术，使汽车用深冲钢板的质量进步日新?
The metallurgical technology of automotive panels has a close relationship with automobile manufacturing technology and quantity development. This is evident from the development of major steel manufacturing technologies in Japan in the past 40 years (Figure 1 [1]). In the past a large number of research work has basically found the composition of the steel, the intrinsic relationship between organization and performance. So, through the continuous use of advanced process control technology, so that the quality of deep-drawn steel for the automotive progress?
