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.
