Abstract

Un procédé de formation d'un article peut comprendre les étapes consistant à : chauffer un métal de façon à obtenir un métal fondu ayant une température de métal ; chauffer un moule jusqu'à une température de moule supérieure ou égale à la température du métal ; introduire le métal fondu dans le moule ; refroidir une première partie du métal fondu tout en maintenant une seconde partie du métal fondu à la température du métal, la première partie ayant des premier et second côtés, le second côté étant opposé au premier et adjacent à la seconde partie et le refroidissement consistant à refroidir progressivement la première partie depuis le premier côté jusqu'au second côté d'une manière telle qu'une interface de solidification progresse du premier côté jusqu'au second côté ; et refroidir le reste du métal fondu à partir de multiples directions une fois la première partie refroidie jusqu'à une température inférieure ou égale à une température de cristallisation.
