With taking hypereutectic Al-Si alloys as light weight wear-resistant materials, the creation of hetero-structure is examined to be consistent with strength and ductility.Semisolid slurry was prepared by sono-solidification with irradiated ultrasound on molten metal during the solidification.Shaping was then performed by rheocasting with the sono-solidified slurry.The hetero-structure composed of soft (alpha)-Al and hard primary Si particles is created by rheocasting with sono-solidified slurry, which exhibits high strength/wear resistivity and ductility.

通过将过度的Al-Si合金作为轻度磨损的材料，研究了异质结构的创建与强度和延展性一致。在固体过程中，通过对熔融金属的辐照超声来制备脱蛋白浆液。然后通过用声固化的浆液进行晶状体铸造进行。异质结构由软（alpha） - al和硬主要SI颗粒组成，是由带有声溶解的浆液塑料产生的，它具有高强度/磨损能力/磨损的能力和耐牙作用。
