【摘要】 使用氟钛酸钾、石墨与铝制备AlTiC中间合金。用扫描电镜和透射电镜分析了TiC粒子在制备过程中不同阶段的形态。在TiC生成热力学条件的研究基础上,提出了K2TiF6与石墨在铝液中的直接反应是TiC粒子的主要形成机制。更多还原

【Abstract】 Aluminum-thermal reaction between K₂TiF₆,graphite and aluminum melt was used to prepare AlTiC alloys.The preparation process of AlTiC intermediate alloys was investigated by SEM and TEM.Experimental results indicate that direct reaction between carbon and K₂TiF₆ dominates the TiC synthesis process compared to other mechanisms.更多还原
