Formation of a Dense Product of the Ti–B–Fe System by Self-propagating High-Temperature Synthesis

Abstract

The possibility of obtaining a dense material of the Ti–B–Fe system in one stage in a self-propagating high-temperature synthesis has been studied. The influence of some process parameters on compaction of the reaction products of the Ti–B–Fe system, which has high physicomechanical characteristics, was examined. It was established that the formation of a nonporous product during combustion of the Ti–B–Fe system is most greatly affected by the maximum temperature developed in the combustion wave, the use of ferroboron alloys as initial reagents, annealing of the initial powders, and preliminary heating of the charge before the self-propagating high-temperature synthesis.
