Carbide dispersed, strengthened copper alloy

Abstract

A carbide dispersed, strengthened copper alloy includes copper as a major constituent, carbide particles, and a dispersing agent. The carbide particles consist of one or more carbides selected from chromium carbide, tungsten carbide, molybdenum carbide, and tantalum carbide. The dispersing agent consists of one or more elements selected from magnesium, chromium, silicon, and aluminum.

What is claimed is:  
     
         1 . A production method of a carbide dispersed, strengthened copper alloy comprising the steps of: 
 adding carbide particles and a dispersing agent into a bath containing a molten-metal that includes copper as a major constituent, and    stirring said molten-metal in the bath.    
     
     
         2 . A production method set forth in  claim 1 , said carbide particles consist of one or more carbides selected from chromium carbide, tungsten carbide, molybdenum carbide, and tantalum carbide.  
     
     
         3 . A production method set forth in  claim 1 , said carbide particles consist of trichrominium dicarbide.  
     
     
         4 . A production method set forth in  claim 1 , said dispersing agent consists of one or more elements selected from magnesium, chromium, silicon, and alumimum.  
     
     
         5 . A production method set forth in  claim 2 , said dispersing agent consists of magnesium.  
     
     
         6 . A production method set forth in  claim 3 , said dispersing agent consists of magnesium.  
     
     
         7 . A carbide dispersed, strengthened copper alloy comprising copper as a major constituent, carbide particles, and a dispersing agent.  
     
     
         8 . An alloy set forth in  claim 7 , said carbide particles consist of one or more carbides selected from chromium carbide, tungsten carbide, molybdenum carbide, and tantalum carbide.  
     
     
         9 . An alloy set forth in  claim 7 , said carbide particles consist of trichrominium dicarbide.  
     
     
         10 . An alloy set forth in  claim 7 , said dispersing agent consists of one or more elements selected from magnesium, chromium, silicon, and aluminum.  
     
     
         11 . An alloy set forth in  claim 8 , said dispersing agent consists of magnesium.  
     
     
         12 . An alloy set forth in  claim 9 , said dispersing agent consists of magnesium.
