Abstract

L'invention concerne un procédé d'affinage de silicium primaire dans des alliages hypereutectiques, qui consiste à mélanger un alliage hypereutectique et un alliage hypoeutectique solide/semi-solide. Le procédé permet de régler la morphologie, la taille et la distribution de Si primaire dans un moulage Al-Si hypereutectique par le mélange d'un liquide hypoeutectique Al-Si et d'un liquide hypereutectique en vue d'obtenir des propriétés mécaniques voulues.
