Abstract

L'invention concerne un produit métallique moulé formé dans un moule d'agrégation et présentant une fine microstructure de solidification plus fine que la microstructure de solidification d'un produit métallique analogue obtenu avec des procédés de moulage classiques. La microstructure de solidification peut être jusqu'à cinq fois plus fine que la microstructure de solidification d'un produit moulé classique. Dans des modes de réalisation préférés, comme résultat d'une solidification directionnelle, la fine structure de solidification est sensiblement continue d'une extrémité distale du produit moulé vers une extrémité proximale du produit moulé, et présente une qualité sensiblement améliorée. Le réglage de l'uniformité de solidification du produit moulé permet d'obtenir un produit avec des propriétés sensiblement uniformes.
