Structure and Properties of Titanium Nitride Strengthened Microlaminate Metal Matrix Composites

Abstract

Microlaminate composites with two-dimensional strengthening have be en successfully fabricated using reactive ion plating and hot pressing. The composite materials have been mechanically tested and characterized structurally and chemically. It has been observed that these laminate composite can be carefully designed to exhibit strengthening much greater than that predicted by the simple rule-of-mixtures and still maintain reasonable ductility. However, composite strengthening is limited by reinforcement precracking, diffusion bond delamination, and matrix/reinforcement reaction. From the results of this research, a fundamental understanding of these engineered composite materials has been developed and specifically the relationships between: (1) ion plating plating and vacuum hot press processing parameters; (2) microstructure and microchemistry of the composite and interfaces; and (3) mechanical behavior and the micromechanics of deformation and fracture.
