摘要
研究了高纯金属Ti和CuCr合金在不同的工艺条件下的扩散焊接性能和界面情况。结果表明,真空封焊的退火态CuCr合金和高纯Ti样件经过525℃/120 MPa/4h的热等静压,平均焊接强度能达到133.6 MPa以上,焊接界面达到冶金结合,焊接可以满足Ti靶材的使用要求。
The diffusion bonding properties and interface of high-purity Ti and CuCr alloys were studied under different conditions.The results show that the vacuum-sealing sample with high pure Ti and annealed CuCr alloy was put on 525 ℃/120 MPa hot isostatic pressing furnace for 4 h,the average welding strength of sample can reach more than 133.6 MPa,the welding interface of sample achieves metallurgical bonding,the diffusion bonding property of sample can meet the requirements of Ti target.
