Abstract
The invention relates to a composite material comprising a matrix mainly constituted by an intermetallic compound of the AlNi type containing in solid solution 1.5 to 30 atom % silicon and a reinforcement formed from silicon carbide (SiC) particles dispersed in said matrix. In said material, the presence of silicon leads to a thermodynamic equilibrium system no longer evolving by SiC reinforcement/matrix chemical reaction when raised to a high temperature. This material can be prepared by conventional processes by adding the silicon to the starting material or by carrying out a limited reaction during the preparation between an AlNi matrix and the silicon carbide particles.
