Design of metal matrix composite with particle reinforcement produced by deep cryogenic treatment

Abstract

One mechanism for strengthening and increasing toughness of composites is through debonding mechanism. Interface strength between reinforcement particles and matrix and the effective surface of debonding greatly affect toughness and strength of the composites. In this study, a model was proposed to estimate the effect of interface and matrix strength of composites on increasing tensile toughness and strength. Then, interface strength and its effect on increasing tensile toughness and strength were calculated in a case study on composites containing particle reinforcement in matrix of deep cryogenic treated steel. Using the methods for estimating strength and toughness of composites reduces trial-and-error time in the design process.
