The influence of forming processes on the distribution and morphologies of TiC in Al-Ti-C master alloys

Al-Ti-C master alloys were prepared using a melt reaction method. It is found that the distribution and morphologies of TiC are influenced mainly by the synthesis temperature and it is difficult to improve them by increasing the melting temperature once the TiC particles have been formed. It is supposed that different synthesis temperatures result in different forming processes for TiC, which account for the distribution and morphologies of the TiC particles.
