Method of reinforcing low melting temperature cast metal parts

Abstract

A method of reinforcing a low melting temperature cast metal part comprising preparing a molten metal material having a melting temperature, mixing a reinforcing material having a melting temperature greater than the melting temperature of the molten metal material into the molten metal material, pouring the molten metal material into the mold, applying a force to the reinforcing material causing the reinforcing material to occupy a predetermined portion of the mold and thereby a predetermined portion of the cast metal part, and solidifying the molten metal material.

1 . A method of reinforcing a low melting temperature cast metal part comprising:
 preparing a molten metal material having a melting temperature;   mixing a reinforcing material having a melting temperature greater than the melting temperature of the molten metal material into the molten metal material;   pouring the molten metal material into the mold;   applying a force to the reinforcing material causing the reinforcing material to occupy a predetermined portion of the mold and thereby a predetermined portion of the cast metal part; and   solidifying the molten metal material.   
   
   
       2 . The method as in  claim 1  comprising applying a magnetic force. 
   
   
       3 . The method as in  claim 1  comprising applying a centrifugal force. 
   
   
       4 . A method of reinforcing a low melting temperature cast metal part comprising:
 preparing a molten metal material having a melting temperature;   adding a reinforcing material having a melting temperature greater than the melting temperature of the molten metal material to the mold;   applying a force to the reinforcing material causing the reinforcing material to occupy a predetermined portion of the mold and thereby a predetermined portion of the cast metal part;   pouring the molten metal material into the mold; and   cooling the molten metal material.   
   
   
       5 . The method as in  claim 4  comprising applying a magnetic force. 
   
   
       6 . The method as in  claim 4  comprising applying a centrifugal force. 
   
   
       7 . The method as in  claim 4  comprising applying a static electric charge to a mold surface. 
   
   
       8 . A method of reinforcing a low melting temperature cast metal part comprising:
 preparing a molten metal material having a melting temperature;   adding a reinforcing material having a melting temperature greater than the melting temperature of the molten metal material to the mold in a predetermined location;   pouring the molten metal material into the mold; and   cooling the molten metal material.   
   
   
       9 . The method as in  claim 8  comprising retaining the reinforcing material in a predetermined position in the mold by application of a magnetic force. 
   
   
       10 . A method of reinforcing a low melting temperature cast metal part comprising:
 preparing a molten metal material having a melting temperature;   mixing a predetermined amount of reinforcing material having a melting temperature greater than the melting temperature of the molten metal material into the molten metal material;   pouring the molten metal material into a predetermined portion of the mold, said portion constituting less than the total volume of the mold;   preparing a second molten metal material having a melting temperature;   pouring the second molten metal material into the mold remainder; and   solidifying the molten metal material and the second molten metal material.   
   
   
       11 . The method as in  claim 10  comprising segregating the predetermined portion of the mold from the mold remainder by occupying the mold remainder so as to exclude molten material from the mold remainder during pouring into the predetermined portion of the mold.
