摘要：

对纯钽板的胀形性能以及纯钽板在拉深成形过程中的润滑问题进行研究。利用冲杯试验机完成厚度为0.5 mm的纯钽板冲杯试验，得到纯钽板数次冲杯试验的IE均值为8.74 mm，破型力均值为6.976 kN。结果显示，纯钽板胀形性能和塑性与低碳钢相近，其强度高于低碳钢。在拉深试验研究中设计了一副以Si3N4陶瓷作为凹模材料的模具，并分析了润滑介质对纯钽制件表面质量和开口处材料流动性的影响。结果表明:使用陶瓷模具能明显减少纯钽板的表面粘结瘤现象；选用合适的润滑介质可降低纯钽制件的表面粗糙度，并提高纯钽板成形时材料的流动性。

The bulging properties of pure tantalum sheet and the lubrication problem of pure tantalum sheet in drawing forming process were studied. Then, the cupping test of pure tantalum sheet with thickness of 0.5 mm was conducted by cupping test equipment, and the mean values of IE for several cupping tests of the pure tantalum sheet and breaking force were 8.74 mm and 6.976 kN, respectively. The results show that the bulging properties and plasticity of pure tantalum sheet are similar to those of low carbon steel, and its strength is higher than that of low carbon steel. Furthermore, the die with ceramic Si3N4 was designed in the drawing test, and the influences of lubrication mediums on the surface quality of pure tantalum parts and the material fluidity at the opening were analyzed. The results show that the using ceramic die can significantly reduce the surface seizing tumour of pure tantalum sheet, and the surface roughness of pure tantalum parts can be reduced and the material fluidity can be improved by choosing suitable lubrication medium.
