Abstract
A method for manufacturing near net shapes of complex configuration components. The method includes mixing a plurality of powdered metals to form a blended powder; gravity sintering a sand mold filled with the blended powder to form a gravity sintered preform; and vacuum hot-pressing the gravity sintered preform to form a near net shape component.
Claims7
A system, comprising:
- a sand mold printer configured to print a modular stackable sand mold;
- a powder blender configured to mix a plurality of powdered metals or metal alloys to form a blended powder, wherein the plurality of powdered metals includes titanium hydride (Ti2H), aluminum (Al), vanadium (V), and iron (Fe);
- a gravity sintering furnace configured to gravity sinter the modular stackable sand mold filled with the blended powder to form a gravity sintered preform;
- and
- a vacuum hot-pressing die configured to vacuum hot-press the gravity sintered preform to form a near net shape component.
