A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

An apparatus for countergravity casting a metallic material, comprises: a crucible for holding melted metallic material; a casting chamber for containing a mold; a fill tube capable of extending into the crucible to communicate melted metallic material to the casting chamber; a gas source coupled a headspace of the melting vessel to allow the gas source to pressurize said headspace to establish a pressure differential to force the melted metallic material upwardly through said fill tube into said mold; and means for gettering sulfur.

A counter gravity casting apparatus includes a reusable metal mold having a plurality of mold cavities, a feed tube configured to feed molten alloy into the mold, and a vacuum fitting configured to permit a vacuum to be applied to the mold. The mold includes multiple metal sections configured such that adjacent metal sections mate to one another, the metal sections being separable from one another. The metal sections include recesses that form the mold cavities, and the mold includes a sprue and multiple runner passages. The sprue is configured to receive molten alloy from the feed tube, and the multiple runner passages are configured to feed molten alloy from the sprue to the mold cavities. Methods of casting bulk amorphous alloy articles or feedstock is described.
