This disclosure is directed at methods for mechanical property improvement in a metallic alloy that has undergone one or more mechanical property losses as a consequence of shearing, such as in the formation of a sheared edge portion or a punched hole. Methods are disclosed that provide the ability to improve mechanical properties of metallic alloys that have been formed with one or more sheared edges which may otherwise serve as a limiting factor for industrial applications. Cette invention porte sur des procédés qui permettent d'améliorer les propriétés mécaniques dans un alliage métallique qui a subi une ou plusieurs pertes de propriété mécanique en raison d'un cisaillement, par exemple dans la formation d'une partie de bord cisaillée ou d'un trou poinçonné. Les procédés selon l'invention permettent d'améliorer les propriétés mécaniques d'alliages métalliques qui ont été formés avec un ou plusieurs bords cisaillés qui peuvent sinon servir de facteur limitant pour des applications industrielles.
