Note (General): We have studied influence of silicon crystal size on tensile and high-cycle fatigue properties for hyper-eutectic Al-20.6 wt% Si materials at 77 K and 296 K. To control silicon crystal size, three kinds of materials, i.e. cast material, spray-formed (SF) one, and repeated thermomechanical treated (RTMT) one, were fabricated. Cracking of coarse primary Si crystal in the cast material led to early fracture under both tensile and fatigue tests. RTMT and SF materials showed much higher uniform elongation than cast one, and refinement of Si crystal was effective to improve the strength-ductility balance. However, fatigue strength of RTMT material was almost the same with that of cast one, although SF material showed higher fatigue strength.
