Abstract
The mechanical properties of two-phase microcrystalline alloys, e.g. Fe-Ce 2S 3, Be-YBe 13, Cr-Cr 2O 3, Fe-CaF 2, (Ni, Cr)-Al 2O 3 and TiC-Al 2O 3, produced using physical vapor deposition as well as other methods, were found to exhibit extreme values of strength and ductility when the volume content of the second phase was low, and when certain observed microstructural conditions were met. These structural condition(s) were easily met when the surface area of the boundaries of the matrix grains was approximately equal to that of the dispersed particles in a unit volume of a two-phase material. At elevated temperatures, the role of the dispersed particles cannot be regarded as principal in retarding grain growth, but are more complex in behavior. Numerous microstructural data from two-phase alloys were assimilated in the form of a nomograph that has been proposed for applicability in the microstructural design of two-phase crystalline materials for maximum strength, ductility and fracture toughness.
