Mechanical Alloying for Heat-Resistant Copper Alloys

In the development of heat-resistant, high-conductivity copper alloys, beneficial properties may be obtained through the application of mechanical alloying. Mechanical alloying has been applied to copper-base materials with the ultimate goal of obtaining improved elevated-temperature performance through oxide dispersion strengthening in a complex matrix that has been solute- or precipitation-strengthened. Preliminary results indicate that a random distribution of fine oxide particles can be obtained in a copper matrix through high-energy attritor milling.
