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.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
