| Research Abstract |
Semi-solid casting of AC4CH aluminum alloy (hereinafter, SS) was used for this research. Furthermore, ultrafine-grained metal (hereinafter, SS-ECAP) was fabricated by Equal-Channel Angular Pressing using SS material. Formability of these test materials was evaluated by an impact molding method to form thin-walled housing. This method is how to give impact load to the light weight metal of bulk at high speed, and extrude to backward from narrow clearance by high pressure. As a result, AC4CH aluminum alloy modified by semi-solid casting and ECAP processing achieve the improvement in not only the mechanical property but also the workability in impact process. Although it is known that the impact extrusion process can be performed stably to produce the thickness larger than 0.7 mm, a housing having super-thin walled square cross-section with 0.4 mm in thickness can be formed from SS-ECAP material.
