The apparatus comprises: a metal heating mechanism and a negative pressure cooling mechanism. The metal heating mechanism is located above the negative pressure cooling mechanism and is connected thereto by a nozzle. The negative pressure cooling mechanism comprises a vacuum chamber having an air inlet hole and an air outlet hole, and a three-dimensional moving ingot mechanism disposed inside the vacuum chamber. The three-dimensional moving ingot mechanism comprises a moving ingot and a two-dimensional moving platform vertically connected to the moving ingot. A water cooling mechanism is disposed outside the moving ingot, and the moving ingot is driven by a precision motor to precisely move up and down.

摘要： A method for fabricating a metal-matrix composite tool includes positioning an inner mold within an outer mold and thereby defining a gap between the inner and outer molds. A first reinforcement material is then loaded into the gap, and the first reinforcement material is infiltrated at a first temperature with a first binder material and thereby forming an outer shell. The inner mold is then removed and a second reinforcement material is loaded at least partially into the outer shell and infiltrated at a second temperature with a second binder material and thereby forming a reinforced composite material. The second temperature is lower than the first temperature and the second binder material is different than the first binder material. The outer shell is attached to exterior portions of the reinforced composite material.

摘要： A ladle that can melt and freeze castable metal in a specific manner so that high quality liquid metal and metal alloys may be produced with minimum oxide and hydrogen content. Upon introduction of a quantity of molten metal into the ladle, staged heating and cooling of the molten metal promotes the liberation of previously-dissolved gases from the castable metal, resulting in significant decreases in as-cast porosity.

摘要： Exemplary embodiments described herein relate to methods and systems for casting metal alloys into articles such as BMG articles. In one embodiment, processes involved for storing, pre-treating, alloying, melting, injecting, molding, etc. can be combined as desired and conducted in different chambers. During these processes, each chamber can be independently, separately controlled to have desired chamber environment, e.g., under vacuum, in an inert gas environment, or open to the surrounding environment. Due to the flexible, independent control of each chamber, the casting cycle time can be reduced and the production throughput can be increased. Contaminations of the molten materials and thus the final products are reduced or eliminated.
