| 摘 要： | 采用真空轧制法对6mm厚的奥氏体不锈钢板和50mm厚的碳钢板复合.在高真空、高温和大轧制力的共同作用下,界面实现了牢固的冶金结合并且最终得到了高质量的不锈钢复合板.研究发现界面无开裂和氧化层,仅在界面附近分布少量细小弥散的Si-Mn氧化物颗粒.通过能谱发现不锈钢侧的Cr和Ni向碳钢迁移,在界面形成一薄层富Cr,Ni层,导致复合层硬度升高;碳钢中的C向不锈钢侧迁移导致出现脱碳区,且该区硬度最低.界面的剪切强度达467MPa.

| Abstract: | 6 mm thick stainless steel and 50 mm thick carbon steel were successfully combined by vacuum rolling cladding(VRC).Metallurgical bond of the clad interfaces was achieved by high vacuum,high temperature and severe rolling force to obtain the stainless steel clad plate with a high quality.In the clad interface,except small amount of fine and dispersed Si-Mn oxides,no crack and oxide layer were observed by optical microscope.Energy dispersive spectroscopy showed that Cr and Ni diffuse from stainless steel side... |
