Nondestructive Characterization of Two-Phase Metal-Matrix Materials

Abstract

The major goal of this program is to study methods for the nondestructive characterization of mechanical properties of two-phase metal- matrix composites such as discontinuous SiC-reinforced aluminum alloys. The methods to be studied are based on the physical nonlinear elastic behavior of solids and utilized measurements of the elastic as well as the accoustoelastic constants. The objectives are to establish both experimentally and theoretically relationships between those parameters which can be measured nondestructively and the percentages of second phase in two-phase systems. Mechanical properties of these systems are derived from the presence of reinforcement second phase in the matrix. The research accomplished during contract No. DAAL03-88-K-0096 of the Army Research Office program is documented in details in 4 theses (1 - 4) and 8 papers (5 - 12). Abstracts of these theses and reprints or preprints of these papers are attached in appendix A.
