| 中文摘要: |
| 为了提高纯铜扩散焊接性能，通过表面机械滚压技术( SMRT)，对纯铜试样进行表面纳米化处理，并在真空下对
纯铜母材和经表面机械滚压处理的纯铜试样分别进行扩散焊接试验，焊接压力10 MPa，保温l h，焊接温度为300℃、
400℃、500 qC。研究结果表明：经过SMRT纯铜表层晶粒达到纳米级别，纯铜试样焊接接头处的显微硬度高于母材试
样；同一温度下，SMRT铜焊接性能优于母材试样。 |

| To improve the diffusion welding properties of fine copper, the experiment was carried out on fine copper after
surface nano-crystallization treatment with Surface Mechanical Rolling Technology (SMRT) . And the tests of fine copper
base metal and copper samples treated by SMR were conducted in the vacuum. with welding pressure of 10 MPa. heat
preservation of I h and soldering temperature of 300 0C . 400 0C . 500 0C respectively. The results show that the surface
layer crystal grain of fine copper after SMRT reaches the nano level. and the micro-hardness of welded joints is higher
than the base metal samples. Under the same temperature. the diffusion welding properties of SMRT copper is
significantly improved. |
