Abstract : A method was developed for investment casting magnesium-lithium alloys into inhibited gypsum-bonded molds. Both prototype castings and separately cast test bars (0.252 inch) were produced. Visual and metallographic examination showed no evidence of metal-mold reaction. Tensile property data were obtained on two previously developed alloys, Mg-14Li-0.5Si and Mg-14Li-5Zn-3Ag-2Si. The strength level and the ductility of the investment-cast test bars were found to correspond with previously measured properties obtained on bars cast into a permanent steel mold (0.505 inch).
