Abstract: Described herein is a method of producing a feedstock comprising a BMG. A powder is compacted to for the feedstock. The powder has elements of the BMG and the elements in the powder have a same weight percentage as in the BMG. Described herein is a method of producing a feedstock comprising a BMG. A powder is compacted into a sheath to for the feedstock. The powder and the sheath together have elements of the BMG and the elements in the powder have a same weight percentage as in the BMG.

Abstract: Various embodiments provide methods and apparatus for forming bulk metallic glass (BMG) articles using a mold having a stationary mold part and a movable mold part paired to form a mold cavity. A molten material can be injected to fill the mold cavity. The molten material can then be cooled into a BMG article at a desired cooling rate. While injecting and/or cooling the molten material, the movement of the movable mold part can be controlled, such that a thermal contact between the molten material and the mold can be maintained. BMG articles can be formed without forming an underfilled part. Additional structural features can be imparted in the BMG article during formation. At least a portion of the formed BMG article can have an aspect ratio (first dimension/second dimension) of at least 10 or less than 0.1.
Abstract translation: 各种实施例提供了用于使用具有固定模具部件和配对以形成模腔的可动模具部件的模具来形成块状金属玻璃(BMG)制品的方法和设备。 熔融材料可被注入以填充模腔。 然后可以以期望的冷却速率将熔融材料冷却成BMG制品。 在注入和/或冷却熔融材料的同时,可以控制可动模具部分的移动,从而可以保持熔融材料与模具之间的热接触。 可以形成BMG制品而不形成底部填充部分。 在形成过程中,可以在BMG制品中赋予额外的结构特征。 所形成的BMG制品的至少一部分可以具有至少10或小于0.1的纵横比(第一尺寸/第二尺寸)。 p>
