Abstract

Regularities of passage of gasless combustion wave through a quartz glass layer separating two cylindrical Ni–Al samples were considered. The time of passage of combustion wave through the quartz glass layer was calculated as a function of layer thickness and initial temperature. The unsteady dynamics and critical conditions of transient combustion process for Ni–Al system were investigated. The mathematical model and calculation results can be used to estimate the critical thickness of quartz glass layer separating SHS-produced samples.
