MACROLAMINATE PARTICLE COMPOSITE MATERIAL DEVELOPMENT.

Abstract

This report describes work accomplished on the development of macrolaminate particle composites. Specimens made from cubical shaped particles had better oxidation resistance and higher compressive strength than those made using plate-like particles. Specimens made using rectangular shaped particles with one axis elongated have nearly comparable oxidation and compressive properties to those made from cubical particles and have higher flexural strength. Flexural strength, compressive deformation and weight loss due to oxidation increase with increasing metal content in the composite. The rate of weight loss due to oxidation increases with increasing metal content. Results from hot pressing, isostatic pressing and warm pressing experiments are summarized. Substantial improvements in sintering of the composite have not been realized either by increasing pressure in the vacuum furnace or through use of wet hydrogen. Yielding in flexural specimens prior to ultimate failure was obtained in specimens sintered in wet hydrogen and not in those sintered in vacuum. (Author)
