Abstract
The yield strength-elongation relationship in cast Al-Cu-Mg-Ag alloys (A201) castings has been investigated by analysing 11 datasets from the literature on premium quality castings. The data representing the elongation for a given yield strength have been found to fall within an envelope, the top limit of which represents the ductility potential of A201 alloy castings. A new quality index for A201 alloy castings is introduced. Moreover, using the fracture toughness equation by Hahn and Rosenfield, the estimated intrinsic fracture toughness values have been found to be consistent with the data reported in the literature.
