Abstract
 Al-4%Ti master alloy was used to refine the microstructure of an A357 aluminium alloy. For higher efficiency of the inoculating process in the alloy a new method has been developed. Electro hydro pulse treatment (EHPT) is able to influence the size and distribution of the inoculating TiAl3 intermetallic particles. The treated alloy exhibited better mechanical properties. Possible mechanisms of the EHPT and the grain refinement are discussed. Key words
