| Research Abstract |
In order to check the extrusion form at the time of continuation processing and improve the mechanical properties, the AC4CH aluminum casting alloy was extruded by the 6 axes ECAP method. When back pressure was applied, generating of the void due to a rapid pressure drop was suppressed. As a result, the improvement in a tensile strength was remarkable at semi-solid material. Furthermore, a continuous feeding is possible for the shape by which was extruded enough to the next pass. As a result, the distortion was maintained by the semi-solid casting and creation of the material whose strength improved by the addition to ECAP method was attained.
