Preparation of Nano-TI(C,N) Reinforced Ti(C,N)-based Cermets

Abstract

Abstract: Ti(C,N)-based cermets were produced by using nanopowders of Ti(C,N). The effects of sintering temperature,
holding time and rate of raising temperature on the properties of Ti(C,N)-based cermets containing 10wt% nanopowders of Ti(C,N) were studied. An
optimum process of preparating cermets was obtained. It was the sintering temperature of 1450℃, holding time of 75min and rate
of raising temperature of 3℃/min. The tensile strength was improved about 36.7% by using the process. The reinforcing mechanisms were
considered chiefly to be grains refining, distributing and solution.

Key words: nanopowders, Ti（C, N）-based cermets, properties, reinforcing mechanisms
