Abstract
Official abstract text for this publication.
The present disclosure generally relates to casting molds including a casting shell surrounding at least a portion of a casting core comprising a first metal component and a hot isostactic pressed second metal component around the first metal component. In one aspect, the first metal component may have a lower melting point than the second metal component. In another aspect, the second metal component may retain some metal powder grain structure.
First claim
Opening claim text (preview).
The invention claimed is: 1. A casting mold comprising: a casting shell surrounding at least a portion of a casting core comprising a first metal component and a hot isostactic pressed second metal component around the first metal component, wherein the first metal component has a lower melting point than the second metal component and the second metal component retains some metal powder grain structure, and wherein the first metal component includes at least one of aluminum, nickel, copper, gold, or silver. 2. The casting mold of claim 1 , wherein the first metal component includes an alloy. 3. The casting mold of claim 1 , wherein the second metal component includes tungsten or a tungsten alloy. 4. The casting mold of claim 1 , wherein the second metal component includes molybdenum or a molybdenum alloy. 5. The casting mold of claim 1 , wherein the casting shell includes ceramic. 6. The casting mold of claim 1 , wherein at least one of the casting shell or the first metal component is formed on a layer-by-layer basis. 7. A casting mold comprising: a casting shell surrounding at least a portion of a casting core comprising a first metal component and a hot isostactic pressed second metal component around the first metal component, wherein the first metal component has a lower melting point than the second metal component and the second metal component retains some metal powder grain structure, wherein the second metal component includes tungsten, a tungsten alloy, molybdenum or a molybdenum alloy. 8. The casting mold of claim 7 , wherein the second metal component includes tungsten or a tungsten alloy. 9. The casting mold of claim 7 , wherein the second metal component includes molybdenum or a molybdenum alloy. 10. The casting mold of claim 7 , wherein the casting shell includes ceramic. 11. The casting mold of claim 7 , wherein at least one of the casting shell or the first metal component is formed on a layer-by-layer basis.
