alloying elements to nickel

alloying elements to nickel

1. 5)aluminium+6)titanium=intermetallic compounds

   • strengthen alloy by stopping dislocation movement
     • creep resistance

2. 4)carbon

   • makes carbides
     • increase creep resistance
       • grain boundary precipitation

3. solid solution

   • 2)cobalt
   • 3)chromium
     • also carbides
     • more importantly oxide surface=corrosion resistance
   • 1) tungsten
     • also carbide formation
