Synthesis of Composites with a Change in the Stress–Strain State under Laser Initiation

Abstract

A coupled model of solid-phase combustion was formulated for the conditions of plane stressed and plane deformed state. It was shown that the influence of coupling on the stationary combustion wave in these two cases exhibits different effects, which is reflected in the change in the effective parameters. The possibility of synthesizing in situ composites of Al–Ni–Fe₂O₃ and Al–Ti–Cr₂O₃ mixtures on a substrate, which responded differently to changes in the reaction conditions, was demonstrated. Laser radiation was used to initiate combustion. It is possible that continuous control of laser radiation will stabilize the process when the reaction conditions change.
