ABSTRACT:
An Al-Si base alloy to which is added predetermined amounts of Ti, preferably in the range from 0.2 to 1.0 weight percent Ti to significantly improve grain refinement and eutectic modification and to improve soundness and ductility of castings made of such an alloy, as well as reducing wear resistance of the casting. An Al-Ti or Al-Ti-B master alloy is utilized to produce the aforesaid alloy and is added to the melt to achieve the desired Ti level to produce a hypoeutectic and hypereutectic alloys. Alternatively, an Al-Ti-Si master alloy is added to the melt to obtain the desired Ti level for producing hypereutectic alloys.
