Effect of Interfaces in Metal Matrix Composites on Mechanical Properties.

Abstract

The effect of interface condition on the longitudinal and transverse strength of 6061 Al/B composites was investigated. The interface condition was varied by heat treatments at 940 to 1100F for times up to 192 hours, and was characterized by metallography, scanning electron microscopy, and electron microscopy of extracted interface material. Composites with 25 and 48 percent boron filaments were studied with fully annealed and with age-hardened matrices. Some studies were made of the effect of the interface on fracture toughness.
