| 英文摘要 | The formation mechanism to TiC particles formed by in situ reaction in molten aluminum is studied by means of XRD, EPMA, TEM and SEM techniques in this paper. The results reveal that (1) the heat liberated by the reaction 3Al((1))+Ti-(s)-->Al3Ti can ignite the reaction Ti+C-->TiC; (2)diffusion or/and solution-precipitation mechanisms, two well-known mechanisms of TiC particle formation in Self-propagating High-temperature Synthesis(SHS), are thought to be in operation. At lower temperatures, the reaction leading to TiC particle formation is controlled by a diffusion mechanism of relatively slower velocity. In this regime, the aluminum powders melt with increasing temperature of the preform, thereby igniting TiC particle reaction. At the higher temperatures, the reaction Ti+C-->TiC is controlled by the solution-precipitation mechanism, i.e. the diffusion and solution-precipitation mechanisms are both present in this regime. |
