摘要：

The effects of solute-related defects in AlCo are measured by changes that they produce in lattice parameter, specific gravity, and elastic moduli. By comparison with the effects of off-stoichiometry on the same parameters in binary Al-Co alloys, the solute-produced defects can be partially characterized. Cell occupancy numbers are calculated and used to infer that vacancies are formed on both sides of stoichiometry and also when solute replaces Al or Co in AlCo. These data are also essential to testing the effects of the solutes studied-Mn, Re, and Ti-on mechanical hardening, to be reported separately in Part II.
