Abstract
The present invention pertains to a method of forming a metal matrix composite. The method comprises the steps of surrounding at least one insert with reinforcement material. Next, there is the step of orienting the insert and reinforcement within a mold. Then, there is the step of infiltrating the mold with liquid metal such that the reinforcement material around the insert is infiltrated. In a preferred embodiment, the insert comprises a hollow core and closed ends and the surrounding step includes the step of wrapping reinforcement around the insert. Preferably, the hollow core is exposed and the insert is leached out with the appropriate leaching solution.
Claims31
A method of forming a metal matrix composite comprising the steps of:
- combining at least one insert with reinforcement material;
- orienting the insert with reinforcement material within a mold chamber of a closed mold;
- and
- infiltrating the mold chamber with liquid metal such that the reinforcement material around the insert is infiltrated and the insert is completely encased within the metal.
A method of forming an electronic package comprising the steps of:
- disposing a weld ring with reinforcement material within a mold chamber of a closed mold;
- infiltrating the mold chamber with liquid metal such that the reinforcement material is infiltrated and the weld ring is completely encased within the metal.
A method of forming a component comprising the steps of:
- disposing at least one cooling channel with reinforcement material within a mold chamber of a closed mold;
- infiltrating the mold chamber with liquid metal such that the reinforcement material is infiltrated and the cooling channel is completely encased within the metal;
- and
- exposing the cooling channel such that a fluid can be circulated through the cooling channel.
