Cu-Ti3AlC2 cermets were prepared by powder metallurgical process.The composition and microstructure of the specimens were investigated by X-ray diffraction（XRD）and scanning electron microscope（SEM）.Meanwhile

effects of Ti3AlC2 content on the density

Vickers hardness

flexural strength

fracture toughness and electric conductivity of Cu-Ti3AlC2 cermets were investigated.The results show that with increasing in sintering temperature

peak position of Cu diffraction shifts to low angles as a result of Al solid solution.With increasing in Ti3AlC2 content

density and fracture toughness of the specimens are gradually decreased

and the Vickers hardness and electric conductivity are increased

while flexural strength exhibits firstly increase and then decrease.With 30% Ti3AlC2 content

the cermets exhibit desirable comprehensive properties

where Vickers hardness

flexural strength

fracture toughness and electric conductivity reach up to 1.7GPa

733MPa

9.3MPa·m1/2

1.37×106 S/m

respectively.
