Abstract
A method of making an article includes forming a molten material by melting at least a portion of a mass of a metal and an alloy. The method further includes forming the article by solidifying at least a portion of the molten material within a mold, and contacting the article with plasma during formation of the article. A method for making an article also is disclosed wherein a molten material is formed by melting at least a portion of a mass of one of a metal and an alloy, the molten material is collected within a mold, and at least a portion of the molten material is magnetohydrodynamically stirred within the mold.
Claims26
A method of making an article, the method comprising:
- forming a molten material by melting at least a portion of a mass of one of a metal and an alloy;
- forming the article by solidifying at least a portion of the molten material within a mold;
- and
- contacting the article with a plasma while forming the article in the mold.
A method for producing a material comprising:
- forming a molten material by melting at least a portion of a mass of one of a metal and an alloy;
- collecting the molten material within a mold;
- and
- magnetohydrodynamically stirring at least a portion of the molten material within the mold.
An article of manufacture comprised of a material made by a process comprising:
- forming a molten material by melting at least a portion of a mass of one of a metal and an alloy;
- forming the material by solidifying at least a portion of the molten material within a mold;
- and
- contacting the material with a plasma while forming the material in the mold.
An article of manufacture comprised of a material made by a process comprising:
- forming a molten material by melting at least a portion of one of a metal and an alloy;
