Reaction model for the boron carbide/aluminium system

Abstract

An attempt has been made to shed light on the reaction mechanism during the production of B4C/Al composites by making use of the measured phase contents of the phases B4C, Al, Al3BC and AlB2. It was found that the agreement between the measured and calculated Al3BC contents is good for all the processing conditions investigated. The measured and predicted Al contents, on the other hand, were oberved to be reasonably close to each other for short holding periods at the infiltration temperature but deviated at higher holding periods.
