Abstract
17 The first experiments on combustion of compacted metal powder samples in a gaseous nitrogen atmo� sphere exhibited two qualitatively different combus� tion modes: a layer mode and a surface mode [1]. In the layer mode, the combustion front is flat and extends over all the cross section of the sample. In the surface mode, the combustion front is strongly curved, and the leading edge of the reaction front propagates within the surface regions of the sample, whereas the reaction in the core part of the sample either occurs far from the leading edge of the front or is absent. The external patterns of combustion in both modes are identical; therefore, a conclusion on the combustion mode is made based on visual observation of cross sec� tions of burnt samples (the formed nitride and the ini� tial metal powder differ in color) and on chemical analysis of samples taken from the burnt samples. The combustion mode was proposed to quantita�
