A fiber-reinforced metal composite (aluminum-matrix composite) consisting essentially of reinforcing fibers and an aluminum alloy containing 6 to 11 wt. % of nickel of a metal matrix.

Fiber-reinforced metal composite

A fiber-reinforced metal composite consisting essentially of continuous reinforcing fibers disposed in an aluminum alloy matrix containing about 0.005 wt % of cobalt.

Continuous fiber-reinforced Al-Co alloy matrix composite

In a method of feeding a molten metal in metal molds through a casting sleeve to cast a predetermined article, a hollow thin-plate body is provided to at least an inner wall surface portion of the casting sleeve near the molds.

Casting method in high-pressure casting

A degassing apparatus, adapted for use in a molding apparatus having a mold cavity, includes a spool having a bore, a gas inlet opening and a gas outlet opening. The gas inlet and outlet openings are in selective communication and non-communication with each other. A reciprocatingly slidable valve body engages a conforming valve seat formed on the spool for selectively controlling the communication and non-communication between the gas inlet and gas outlet openings. A piston is mounted in the bore and coupled to the valve body. The piston is reciprocatingly slidable between a first position and a second position. First and second chambers are situated on opposite axial sides of the piston. First, second and third fluid ports are formed in the spool. The first and second ports are in communication with the first and second chambers, respectively. At least one first channel is formed in the piston and interconnects the first and second chambers, and a second channel formed in the piston interconnects the third port and the first chamber when the piston is in the first position. In the first position, the gas inlet and outlet openings are not in communication, and the molten material is prevented from flowing through the degassing apparatus. The third port and the first chamber are not in communication when the piston is in the second position. In this position, the gas inlet communicates with the gas outlet to allow gas to escape from the mold cavity.
