Abstract

A model has been developed to express the flow stress of two-phase materials in terms of the continuity and grain size of the component materials. The model is based on the original statement of the grain size dependence of the flow stress of a single-phase material and is quite general. However, this general statement does contain some parameters which need to be evaluated for the particular composite of interest. This has been done for ferrite-pearlite composites and some success is claimed in predicting the effects of interlamellar spacing, ferritic grain size and pearlite volume fraction on the flow stress. Ferrite-pearlite structures represent a simplified situation in that it has been assumed that the composite consists of a bimodal distribution of grain sizes of a single phase (ferrite) but it is intended to extend the treatment to ferrite-martensite structures.
