The Mechanical Metallurgy of Directionally Solidified Composites: Strengthening Fundamentals, Tensile, Creep, Fatigue and Toughness Properties.

Abstract

A fundamental basis for the interpretation and prediction of the mechanical behavior of in-situ metal matrix composites is developed by considering possible strengthening mechanisms and associated models. Experimental property data and structural observations are then discussed in light of these mechanisms. The general features of tensile, creep, fatigue and impact loading are characterized and behavior interpreted from the viewpoint of structure. Where possible, observed and predicted response of in-situ composites are compared, as is the behavior of comparable synthetic composites. The various structure-mechanical property correlations allow for a rationalization of the major advantages and disadvantages of in-situ composites vis a vis synthetic composites and other advanced structural materials.
