摘要
采用屏蔽包层第一壁制作工艺对不同状态的CuCrZr合金进行处理,通过室温力学性能和微观组织的分析,获得了适合ITER结构设计的CuCrZr合金。结果显示:经1040℃/150MPaHIP后合金强度降低,热处理后性能得到恢复;580℃/145MPaHIP代替时效处理过程,合金强度下降不大,锻造态EU-Cu晶粒细小,而热轧态SY-Cu晶粒显得异常粗大,能实现时效效果的同时恢复铜合金的硬度,最终表明了锻造态EU-Cu较适合用来在580℃/150MPaHIP进行扩散连接。
The variation of the microstructure and mechanical property of Chinese CuCrZr and European CuCrZr alloys during manufacturing of the ITER First Wall is investigated.The CuCrZr alloy,be suited to the ITER First Wall,is obtained. The results show that the strength of CuCrZr alloy is reduced after 1040℃/150MPa hot isostatic pressing diffusion bonding(HIP),but recovered after heat treatments.After 580℃/150MPa HIP,be instead of the ageing heat treatment,the strength is a few descended.The grain of the forged EU-...
