Abstract
The principles of gasless combustion wave transition through an air gap separating two cylindrical samples of different diameters, prepared from a Ti--Si mixture, are examined. Critical conditions of the transition process are investigated using experimental and computational methods. A mathematical model is proposed, based on which the effective emissivity from the combustion surface is calculated in correlation with experimental data. The emissivity of titanium silicide is estimated.
