Measurements have been made of lattice parameters residual electrical resistivities and microhardness values of AlSc alloys containing up to 3.28at%Sc. The change in lattice parameter a with concentration c is found to be (da/dc)/a=0.122+or-0.011 at%-1, in residual resistivity rho 0/c=3.5+or-0.5 mu Omega cm at%-1 and in relative microhardness (d sigma /dc) sigma =1.0+or-0.1 at%-1. Changes in lattice parameter and residual resistivity support the virtual bound state model of Al-3d alloys and changes in microhardness correlate with deviations from Vegard's law for these alloys.
