摘要: Abstract The room temperature yield strengths of extruded ternary iron aluminides with the composition Fe-45Al-5X-0.2B-0.1Zr (at%), where X stands for Ti, Cr, Mn, Fe, Co, Ni or Cu, were measured. With exception Mn-containing alloy, all alloys showed solid solution strengthening following a 1 week/673 K vacancy removal anneal. Densities, lattice parameters and elastic constants measured to determine concentrations as well atomic size modulus misfits. Although could not be described by established theories dilute binary alloys, it reasonably correlated magnitude misfit alloying additions.
