Hot-Press Sintering of Tic_0.5N_0.5-Based Cermets: Addition Effect of AlN Nano-Powder on Microstructure and Mechanical Properties

Abstract:

TiCN-based cermets were prepared by hot-press sintering through adding various amounts of AlN nanopowder (0-20 wt.%) into a 64 wt.% TiC_0.5N_0.5-10 wt.% WC-8.5 wt.% Mo-12.5 wt.% Ni-5 wt.% Co system. The microstructure and mechanical properties of the prepared cermets were investigated. For the prepared cermets, samples with 5 wt.% AlN nanopowder exhibited optimum mechanical properties of Vickers hardness 2191 HV₁₀, bending strength 601 MPa, and fracture toughness 6.03 MPa.m^1/2, respectively.
