Stability under temperature of expanded austenite developed on <!-- @page { size: 8.27in 11.69in; margin: 0.79in } P { margin-bottom: 0.08in } --> The intensity variations of N2 and N2+ bands with the current density (j) under discharge and post-discharge conditions of a pulsed dc N2-H2 diode plasma have been analysed. It is found that for specific conditions, first a linear variation of N2 bands with j is related to electron collisions on N2 ground and metastable states. Second, the N2+band is varying as j2as a result of two step electron collisions.
