| 摘 要： | 提出一个生产具有极高r的超低碳高强度烘烤硬化钢板（简称ELC-BH钢板）的新工艺，即热轧→卷取→组织预处理→冷轧→退火（快冷）工艺.实验表明，与传统工艺相比，采用新工艺研制的ELC-BH钢板不仅强度和烘烤硬化性未受到损害，而且r值提高到2.67.

| Abstract: | A new process by which an extra low-carbon and high strength bake-hard-ing with very high r-value can be produced is presented. The sheet produced by the process shows the same strength and bake-hardenability as that by conventional technology, but its r-value increases of 2.67. |

| Keywords: | extras-low carbon steels plastic strain ratio high strength bake-hardening |
