铝熔体中原位合成TiC的动力学分析

Kinetic Analysis of in Situ Synthesized TiC in Molten Aluminum

摘要:

探讨了铝熔体中原位合成TiC的反应速度问题。结果表明：减少预制块中Al含量，TiC反应速度加快；富Ti层越厚、C颗粒越粗，TiC反应速度越慢。

Abstract:

The reaction rate of in situ formed TiC in molten aluminum has been studied. The calculated results show that decreasing the aluminum content in Ti-C-Al preform accelerates the reaction rate of TiC. Increasing the thickness of intermetallide layer and the size of C power reduces the reaction rate of TiC.
