Abstract A efficiency Al-Ti-C gain refinement master alloy was prepared by using Shear/Cooling Roll Process (SCR) machine，the melt of AlTi5C0.25 master alloy synthesized by melts-solid reacting was dynamically and directly solidified in shear stress field．The mechanism of microstructure formation and refinement characteristic of master alloy have been investigated．Results showed that SCR forming of melt was a dynamic solidification process had drastic shearing and heat disturbance action on melt，which could affect migration of TiC，made TiC particles distribute dispersely in α-Al，dispersely refined TiAl3 phase，improved significantly the refinement characteristics of Al-Ti-C master alloy．
