description	Embodiments of surface-hardened aluminum-rare earth alloys and methods of making the alloys are disclosed. In some embodiments, the alloy comprises aluminum and 4 wt% to 60 wt% of a rare earth component X having a maximum solid solubility of ≤ 0.5 wt% in aluminum. The surface-hardened alloy component has an alloy bulk portion and a hardened alloy surface portion. At least a portion of the hardened alloy surface portion has a Vickers hardness that is at least 30% greater than a Vickers hardness of the alloy bulk portion. Selon certains modes de réalisation, cette invention concerne des alliages à base d'aluminium/terres rares durcis en surface et des procédés de fabrication des alliages. Selon certains modes de réalisation, l'alliage comprend de l'aluminium et 4 à 60 % en poids d'un constituant de terres rares X ayant une solubilité maximale à l'état solide ≤ 0,5 % en poids dans l'aluminium. Le composant d'alliage durci en surface a une partie de masse en alliage et une partie de surface en alliage durci. Au moins une partie de la partie de surface en alliage durci présente une dureté Vickers qui est supérieure d'au moins 30 % à une dureté Vickers de la partie de masse en alliage.
