Nondestructive Characterization of Interfacial Bonding in Two-Phase Metal-Matrix Composites.

Abstract

The main objective of this contract was to study macroscopic and microscopic methods for the nondestructive characterization of interfacial bonding properties in two-phase metal matrix composites such as alumna-reinforced aluminum alloys. The research obtained is documented in five theses and eight papers whose abstracts are included in the appendix. The major accomplishments are summarized in studies performed to characterize the interfacial bonding by measurements of acoustoelastic constants, acoustic nonlinearity parameter, temperature dependence bf ultrasonic velocity and the coefficient of thermal expansion. Also under this contract a facility to fabricate Aluminum Silicon Carbide composites was developed and is planned to be used in future studies related to this ARO program. (MM)
