Webb1 feb. 2024 · Non-equilibrium molecular dynamics simulations have been used to investigate strain-rate dependence of plasticity and phase transition in [001]-oriented single-crystal iron under ramp compression. Here, plasticity is governed by deformation twinning, in which kinetics is tightly correlated with the loading rate. Over the … Webbför 2 dagar sedan · Recently, the presence of local chemical short-range order (CSRO) in the HEAs affects the defect nucleation/motion, and in turn would control their mechanical properties [[16], [17], [18]]. The effect of such CSRO has been studied in certain fcc/bcc HEAs based on the recent experimental and simulated results [ [19] , [20] , [21] ].
