摘要： Titanium based and nickel based castings are made by casting a suitable melt having a relatively low melt superheat into a mold cavity defined by one or more low carbon steel or titanium mold members where the melt solidifies to form the desired casting. The melt super-heat is limited so as not to exceed about 150.degree. F. above the liquidus temperature of the particular melt being cast. For a steel mold, one or more titanium melt inlet-forming members are provided for cooperating with the steel mold members to form an melt ingate that communicates to the mold cavity for supplying the melt thereto in a manner to avoid harmful iron contamination of the melt during casting. The mold body-to-mold cavity volume ratio is controlled between 10:1 to 0.5:1 to minimize casting surface defects and mold wear/damage.

摘要： A casting mold includes a melt-receiving mold cavity having a preformed metallic or intermetallic insert suspended therein by one or more first elongated, slender suspension members fixed at one end to the insert and at another end to the mold to locate the insert in a first direction in the mold and by one or more second elongated, slender suspension members fixed at one end to the insert and abutting the mold at another end to locate the insert in a second direction in the mold. A melt of metallic or intermetallic material is introduced into the mold cavity about the suspended insert and the suspension members and is solidified to form a composite casting. The casting is subjected to elevated temperature/elevated isostatic gas pressure conditions wherein the interface between the suspension members and the cast melt is effective to inhibit gas penetration between the insert and cast melt, thereby allowing a sound, void-free, contamination-free metallurgical bond to be produced between the insert and the cast melt.

摘要： A method of making a composite casting wherein a casting mold is provided having a melt-receiving mold cavity and a preformed metallic or intermetallic insert located in a predetermined position in the mold cavity. A melt is introduced into the mold cavity about the insert and is solidified to provide a composite casting having one or more interfaces between the insert, or an insert positioning member, and cast/solidified metal about the insert. The interface is exposed on or communicates with an exterior surface of the composite casting. After separation from the mold, the composite casting is subjected to a sealing operation to gas-tight seal the interface(s) at the exterior casting surface. For example, the interface can be sealed by providing fused material at the interface. After the interface(s) is (are) sealed, the composite casting is subjected to elevated temperature and isostatic gas pressure conditions effective to produce a sound, void-free, contamination-free metallurgical bond between the insert and the cast melt thereabout. The previously sealed interface(s) prevent the pressurizing gas from entering and migrating between the insert and the cast melt so as to enable formation of the sound, void-free, contamination-free bond.
摘要翻译： 一种制备复合铸造的方法，其中提供具有熔体接收模具腔的铸模和位于模腔中的预定位置的预成型金属或金属间插入件。 将熔体引入到模具腔内，并且固化，以提供在插入件或插入件定位构件之间具有一个或多个界面的复合铸件和围绕插入件的铸造/固化金属。 该界面暴露在复合铸件的外表面上或与复合铸件的外表面连通。 在与模具分离之后，对复合铸件进行密封操作，以在外部铸造表面上气密地密封界面。 例如，可以通过在界面处提供熔融材料来密封界面。 在密封界面之后，复合铸件经受高温和等静压气体压力条件，有效地在插入件和铸造熔体之间产生声音，无空隙，无污染的冶金结合。 先前密封的界面防止加压气体进入和移动插入件和铸造熔体之间，以便形成声音，无空隙的无污染的粘合。

摘要： A method for die casting an amorphous metal or alloy using high vacuum die casting machine and die casting parameters effective to produce three dimensional net shape die cast components that retain at least 50 volume % or more amorphous phase in the die cast microstructure. The die cavity is evacuated to a vacuum level of less than 1000 microns through the shot sleeve, a superheated molten amorphous zirconium-copper-nickel-berylium alloy is introduced into the shot sleeve, the plunger is advanced at speeds in the range of 5 inches/second to 500 inches/second to force the molten metal or alloy into a sealed, evacuated die cavity where at least the outer surface or shell of the die cast component can solidify before opening of the dies to break the vacuum seal(s) and expose the cast component to ambient air atmosphere. The die component is removed from the opended dies and quenched in a quenchant medium, such as water, to produce a die cast microstructure including at least 50 volume % amorphous phase.

摘要： A metal or alloy is melted in a vaccuum chamber disposed about an end of a shot sleeve. The opposite end of the shot sleeve is communicated to a die cavity between first and second dies which are disposed in ambient air atmosphere. The dies have one or more vacuum seals therebetween extending about the die cavity to isolate the die cavity from the ambient air atmosphere when the dies are closed. A vacuum thereby is provided in the die cavity through the shot sleeve when the vacuum chamber is evacuated despite the dies being disposed in ambient air atmosphere. The first and second dies are opened after the metal or alloy is die cast in the die cavity for ready removal of the cast component from the die cavity directly to the ambient air atmosphere and then to an optional quenchant medium proximate the dies.
