摘要：
A number of alloys based on the binary CsCl (B2) compound AlRu are tough and also are ductile in compression at room temperature. Alloys that are substoichiometric in Ru tend toward intergranular brittleness, are enriched in Al at the grain boundaries, and are improved by the addition of 0.5 at. pct B. Al47Ru53 + 0.5 at. pct B underwent 33.6 pct true strain in compression at 23-degrees-C and work hardened to 3.1 GPa true stress. Dislocations of slip vectors [100], [110], and [111] have been identified by transmission electron microscopy (TEM) study of plastically deformed samples, so that ample slip systems appear to be present for compatible deformation of polycrystalline samples.
