  1. Mohamed (FAM) LabMechanical Behavior of Engineering Materials famohame@uci.edu http://fam.eng.uci.edu • Research Topics: • Mechanical behavior of engineering materials (metals, alloys, composites, ceramics, nanocrystalline materials) • Correlation between behavior and microstructure • Creep and superplasticity • The role of impurities during superplastic deformation and cavitation • Dynamic recrystallization • Deformation mechanisms in nanocrystalline materials, and nanoscale softening • Modeling of deformation behavior • Significance: • Investigation of mechanical behavior of materials is vital for two primary reasons: • It contributes to the understanding of deformation mechanisms that are operative under certain conditions of variables (stress, temperature, etc.) • It leads to the development of reliable design criteria. • Prof. Farghalli A Mohamed (FAM) • Full Professor • B.S.
