摘要：

The effects of solute-related defects in AlRu 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 Ru alloys, the solute-produced defects can be partially characterized. Cell occupancy numbers are calculated and used to infer that vacancies are formed on the Al-rich side of stoichiometry, but possibly on a less than one vacancy per excess Al atom basis. These data are also needed to test the effects on the solutes studied-Co, Fe and Ti-on mechanical hardening to be reported separately in Part II.
