MOULE DE FONDERIE POUR LA FABRICATION DE PIECES PAR SOLIDIFICATION MONOCRISTALLINE

A foundry mould comprising a device for grain selection for obtaining a monocrystalline solidification is associated with at least one runner (8a, 8b) placed in the vicinity of the regions (4) of a component (1) where an interfering grain germination is liable to appear in the course of controlled s...

Zusammenfassung:	A foundry mould comprising a device for grain selection for obtaining a monocrystalline solidification is associated with at least one runner (8a, 8b) placed in the vicinity of the regions (4) of a component (1) where an interfering grain germination is liable to appear in the course of controlled solidification, thus forming a thermal mass separated from the cast component.
