Al/0Cr18Ni9Ti bimetallic composite is prepared with the vacuum warm compaction diffusion method under the condition of 480 ℃ compaction temperature
10 MPa pressure and 1.0×10

Pa vacuum. The structures and performances of the two bimetallic composite bonding interfaces and matrix are analyzed respectively with scanning electron microscope
X-ray diffractometer and Vickers microhardness scale. It is found that under the condition of diffusion bonding

form in the Al/Ni interface less than 4 μm in thickness; and no intermetallic compound forms in the Ni/0Cr18Ni9Ti
diffusion zone with about 8 μm in thickness.
