摘要
研究了高纯Ti和Cu62Zn38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,热等静压温度为510℃时,加工态Ti板硬度下降明显,与退火态Cu62Zn38接近;退火态Ti板和退火态Cu62Zn38两种材料硬度较为接近,而在温度接近525℃时,退火态Cu62Zn38合金硬度明显高于退火态Ti板。退火态Cu62Zn38合金与退火态高纯Ti经过焊接温度525℃,压力120 MPa,保温4 h的扩散焊接后,平均抗拉强度能达到136 MPa,焊接界面达到冶金结合,满足Ti靶材的使用要求。
The interracial condition and joint properties of diftusion bonded high-purity Ti and Cu62Zn38 alloy joint were studied under dift^rent welding condition. The results showed that hardness of Cu62Zn38 and Ti was about the same when the hot isostatic pressing temperature was 510 ℃. Hardness of annealled Cu62Zn38 was higher than annealled Ti when the temperature rises to 525 ℃. The average tensile strength of sample can reach 136 MPa with the diffusion bonding temperature of 525 ℃ and hot isostatic press 120 MPa lasting for 4 hour. The welding interface of sample achieves metallurgical bonding and the joint properties of the sample can meet the requirements of Ti target.
