| 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 TiO 2, TiO and TiCrO 3 , and the reasons for TiCrO 3 formation are analyzed. |
