The spontaneous emergence of heterogeneous dislocation patterns is a conspicuous feature of plastic deformation and strain hardening of crystalline solids. Despite long …
In this study, the recovery of strain-hardening rate (RSHR) was discovered for the first time in polycrystalline materials (Ni-Si alloys) that have only dislocation activities during tensile test …
Using atomistic simulations, the effect of jogs on the cross-slip of screw character dislocations and screw-dipole annihilation was examined for both FCC Cu and Ni. The …
Novel atomistic simulations of α-iron nano-crystals starting with pre-existing dislocation networks have been performed to identify the effect of high hydrogen concentrations on …

During the transition from single crystalline to polycrystalline behavior, the available data show the strength increasing or decreasing as the number of grains in a cross section is …
A better understanding of the plastic deformation of metallic materials and their failure can greatly accelerate future material development. However, attaining such an understanding is …
In recent years there has been an increasing interest to utilize ultra-high strength steels (UHSS) in various industries such as transportation, due to the possibility to produce …
