Abstract

A method to simultaneously synthesize and consolidate MoSi2-20vol.%Nb composite and MoSi2-20vol.% ZrO2 composite from powders of Mo, Si, Nb and ZrO2 was investigated. Combustion synthesis was carded out under combined electric field and mechanical pressure. Highly dense MoSi2-20vol.%Nb and MoSi2-20vol.%ZrO2 composites up to 96% of theoretical density were produced from powders of Mo, Si, Nb and ZrO2 with 60MPa of pressure and 3000A of current on the reactant.
