抄録

A Zn–Al–Cu–Mg alloy for use as a molding tool material has been developed. Acceptable mechanical properties can be obtained in a composition range where the Cu-rich ε phase appears as one of the eutectic components.<BR>An inverse sand mold casting technique that has been developed from trials using small size cylindrical molds is demonstrated to be beneficial for the suppression of microporosity formation, grain growth, and gravity segregation of Al. The mechanical properties of heavy sectioned castings of the alloy are also increased by the casting technique.
