Preparation and Properties of A New Ti3C2-Cu(Al) Cermet Series

摘要

Several Ti3C2-Cu(Al) cermets were prepared by pressureless sintering or by in-situ hot-extruding a mixture of Ti3AlC2 and Cu powders,their microstructure and properties were investigated.The Al of Ti3AlC2 was dissolved and diffused into liquid Cu,forming Ti3C2-Cu(Al) cermet.Due to strong combination between Ti3C2 and Cu(Al),and special network microstructure formed by Cu(Al) phase surrounding sub-micro-sheet layered Ti3C2 phase,the cermets have quite high fracture strength and electric conductivity.Properties of cermets fabricated by in-situ hot-extruding were further increased.
