The influence of microstructural scale on the combination of strength and electrical resistivity in copper based composites
- and others
There are many engineering applications in which composite materials are required to satisfy two or more criteria regarding physical and mechanical properties. An example is the development of two-phase wires or tapes for the fabrication of coils for high field magnets. Simple diagrammatic representations can be developed which display the combinations of properties for a variety of materials in relation to design requirements. For a simple solenoid, these diagrams are based on the development of functions to describe the response of the material in terms of the strength required to resist the Lorentz force and the conductivity required to minimize the ohmic heating in a given pulse of time {triangle}t. Thus on this diagram we can indicate minimum acceptance criteria either in terms of the strength of the magnet in Teslas as horizontal lines or diagonal lines indicating maximum pulse durations. In general, materials for this application will be metallic composites or dispersion strengthened materials.
