Pertinence of the Grain Size on the Mechanical Strength of Polycrystalline Metals

摘要

Motivated by the already developed micromechanical approach (Abdul-Latif et al., 2002, "Elasto-Inelastic Self-Consistent Model for Polycrystals," ASME J. Appl. Mech., 69(3), pp. 309-316.), a new extension is proposed for describing the mechanical strength of ultrafine-grained (ufg) materials whose grain sizes, d, lie in the approximate range of 100 nm
