The Elastic Modulus of Some Dispersed-Phase Composite Materials

  • R. H. Krock


The elastic moduli of a variety of cemented-type powder metallurgy two-phase composite materials were investigated from 300 to 1000°K using a dynamic test apparatus. Correlations were made between the experimental elastic moduli values and those predicted from elasticity theory. The extent of agreement with theory was explained in terms of the relative elastic properties of the two phases. The composite thermal expansion coefficient was calculated from the elastic moduli values, and exhibited good agreement with experimental values.
