Study of the Formation Process of Combustion-synthesized(Ti,W)C AITranslate
Abstract AITranslate
The phase composition and microstructures of the combustion-synthesized products with ratios of W/(Ti+W) of 0.4 and 0.54 in Ti-W-C system were studied.The kinetic high-temperature reaction process in the combustion front was analyzed through quenching of combustion front.The study results showed that there existed two reaction models.The first is defined as melt-solution-precipitation mechanism;Ti powder in the combustion front is molten at high combustion temperature,W and C are dissolved into liquid Ti,Ti-W-C melt is formed and (Ti,W)C is precipitated from the Ti-W-C melt.The second is described as diffusion-solution-in-solid state;when the combustion temperature is not high enough to melt Ti powder in the combustion front,C diffuses rapidly along cracks formed during combustion process and reacts with Ti to form TiC,meanwhile W 2C is formed and transformed to WC through C diffusion,then WC is dissolved into TiC to form(Ti,W)C.
