Conclusions

The process of formation of composites in the Cu-Ti-Al system during thermoreaetive sintering has a diffusional character, and the resultant microstructure therefore consists of various intermetallic compounds and remains of the starting components. Varying the titanium content of these composites brings about both quantitative and qualitative changes in their structure. The most homogeneous structure is obtained in alloys with 35–45% Ti, whose end products contain the least amount of the starting components. Composites with 15–30% Ti are characterized by a comparatively high level of physicomechanical properties. These alloys can be recommended as matrix materials for the working layers of superhard abrasive tools.
