摘要：

Cu-Al alloy matrix composites containing in-situ TiC0.5 particles were fabricated by sintering of a mixture of Cu and Ti2AlC powders at 1150 degrees C for 60 min in Ar atmosphere. The micron-sized Ti2AlC particles were decomposed into submicron TiC0.5 grains during the sintering process, meanwhile, Al atoms entered into Cu to form Cu-Al alloy matrix. It was shown that the Cu-Al alloy matrix also consisted of ultrafine grains. Compression tests indicate TiC0.5 particles can improve mechanical properties significantly, and the ductility maintains at a comparatively high level. The fracture strength of 40Ti(2)AlC/Cu sample reaches 1126 MPa with 12.8% fracture strain. The 20Ti(2)AlC/Cu and 30Ti(2)AlC/Cu samples keep undamaged even after the strain of 26.7%.
