Abstract

The burning behavior of Ti-Cr binary alloys and their burning products are studied by means of direct current simulation burning(DCSB) ignition method. The results indicate that the burning velocity of Ti(>10%)Cr alloys is low. If the alloying element Cr content is greater than 15% the burning speed is lower. Burning product surface cracks and their oxide scales are porous. The interface between burning products and matrix is also porous for Ti-(<10%)Cr alloys, which can not retard oxygen diffusion into the matrix. While the interface of Ti-(>10)Cr alloys is tenacious, which can retard oxygen diffusion into the matrix and decrease the burning velocity. The products of Ti-Cr alloys are TiO₂, TiO and TiCrO₃, and the reasons for TiCrO₃ formation are analyzed.
