Abstract
A method and system for reducing hot tearing during solidification of a casting are provided. A mold has a molding surface, and a raised surface feature defined by spaced ribs formed on the molding surface is along a length dimension of the molding surface. The surface feature is configured to reduce hot tearing of the casting along the length dimension of the molding surface by maintaining actual stress of a molten material below an ultimate yield strength of the material during solidification.
Claims20
A method of reducing hot tearing during solidification of a casting, the method comprising:
- providing a mold having a molding surface;
- providing a raised surface feature along a length dimension of the molding surface;
- and
- configuring the surface feature to reduce hot tearing of the casting along the length dimension of the molding surface by maintaining actual stress of a molten material provided in a cavity defined by the mold below an ultimate yield strength of the material during solidification.
A system for reducing hot tearing during solidification of a casting, the system comprising:
- a mold configured to mold a molten material arranged in a mold cavity, the mold having a molding surface;
- a raised surface feature along a length dimension of the molding surface, the surface feature is defined by spaced ribs formed on the molding surface;
- and
- wherein the surface feature is configured to reduce hot tearing of the casting along the length dimension of the molding surface by maintaining actual stress of the molten material below an ultimate yield strength of the material during solidification.
