低成本钛−铜金属复合型材的热挤压成形
(西北有色金属研究院，西安710016)
摘 要: 采用无压余热挤压法制备钛−铜金属复合型材，对扁形棒进行拉剪强度检测，观察结合层的组织形貌及拉剪断口形貌等。结果表明：利用回收的钛、采用无压余热挤压法可以生产钛−铜金属复合型材，制备的型材性能稳定，生产工艺可行；该方法可以提高生产效率，降低原材料成本。

Abstract:The Ti-Cu clad rod was prepared by hot extrusion forming. The strain and shearing strength of the flat clad rod was tested in order to check the microstructure of clad section and zone of shearing fracture. The results show that the procedure of manufacturing Ti-Cu clad rod with titanium scrap is feasible. The method can improve product efficiency and decrease cost of raw material.
Key words: titanium scrap; Ti-Cu clad rod; hot extrusion forming
