| 摘要 | In order to improve the mechanical properties of Ti3AlC2, near-fully dense Ti3AlC2/TiB2 composites were synthesized using Ti, Al, graphite, and B4C powders as the initial materials. Compared with monolithic Ti3AlC2, the composites exhibit a much higher strength (for the compressive strength, from initial 723 MPa to maximal 2205 MPa; for flexural strength, from initial 340 MPa to maximal 861 MPa), and the strengthening effect can be held at least up to 1100 degrees C. Moreover, besides the enhancement of the elastic modulus and hardness of Ti3AlC2, the introduction of a TiB2 phase makes a positive contribution to its electrical conductivity. |
