摘要：
Enthalpies of solutions and misfit strains for the Al-X (X=H, B, C, N, and O) binary alloys were determined by first-principles calculations to estimate the strengthening of solid solutions caused by interstitial atoms. The results indicate that interstitial solute atoms produced large misfit strains. Electrodeposited Al containing 0.12-1.32 at.% C was used to assess the validity of solid-solution strengthening by interstitial solute atoms. The role that interstitial carbon plays in strengthening electrodeposited Al is discussed.
