High-entropy alloy Medium-entropy alloy Peierls stress Dislocation core structure Solute strengthening 1. Introduction Conventional alloys typically contain only one primary element, with small amounts of alloying elements added to enhance specific physical properties. In contrast, medium- and high-entropy...
Specifically, an fcc Fe-20Cr-25Ni system is studied; the alloy is the based alloy for Alloy 709. The number of defects is calculated using Wigner-Seitz analysis in order to illustrate the effect of dislocations on cascades. The displacement cascades in systems containing dislocations tend to ...
Peierls stresses (τP) of dislocations of 66 slip systems in 52 crystals were estimated from experimental data either by direct extrapolation of the critical resolved shear stress (τc) vs. temperature curve to absolute zero temperature, or from the T0 value at which the temperature dependence of...

Therefore, this method is\nparticularly useful in providing insight into alloy design when empirical\npotentials are not available or not reliable for such multi-element systems. As\nan example, we study dislocation cross-slip and constriction process in two\ncontrasting fcc metals, Al and Ag. ...
