Clearing-up of metallurgical points topay attention toonapplication of rapid resistance heating to hot-stamping process combined with press-quenching

在采用热冲压与压淬火相结合的方法生产高强度钢板零件的情况下，电阻加热方法的应用在汽车工业中引起了广泛的关注。本文以实际使用的热冲压钢板为实验材料，对应用中应注意的冶金问题进行了实验研究。通过调查整理的要点在国内外相关学术会议上发表，并转用于实际应用。

In the circumstances that a use of the hot-stamping process combined with press-quenching which can produce high-strength steel sheet parts has been increasing, application of a resistance heating method to the process draw much attention in automotive industry. In this study, metallurgical points to pay attention to on the application were experimentally investigated using a practically used hot-stamping steel sheet as an experimental material. The points cleared up through the investigation were published in relevant academic conferences at home and abroad to turn to practical use.
