Notes:
Al-Ti-C grain refiners have been prepared by combining self-propagatinghigh-temperature synthesis (SHS) technique and melting-casting method. Effects of Al powder sizeand C/Ti ratio on the microstructures and grain-refining efficiency of Al-Ti-C grain refiners werestudied by OM, XRD, SEM and EDS. The results show that when Al powder size is fine, and C/Tiratio is 1: 8, SHS reaction among the mixed powders can easily carry on in the melt. As a result,the prepared grain refiner consists of blocky Al3Ti and fine TiC particles distributed in Al matrix,and exhibits excellent grain refining performance on commercially pure Al
