摘要

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.
