Ultrasonic Measurements of Elastic Moduli of Thermally Cycled Metal Matrix Composite Precursor Wires

Abstract

Metal matrix composite structures are often made by the consolidation of precursor wires typically on the order of 1 mm in diameter. The elastic and mechanical properties of the consolidated parts depend critically on the elastic and mechanical properties of the precursor wires. The consolidation process involves hot pressing at elevated temperatures. The final end-item products may also be subjected to elevated temperatures in their normal use cycles.
