The hierarchical energy landscape of screw dislocation motion in refractory high-entropy alloys

Xinyi Wang et al.

Summary: This study constructs and reports the potential energy landscape governing screw dislocation motion in high-entropy alloys (HEAs). It reveals a hierarchical and multilevel structure, which retards dislocation movement and can be regulated by introducing chemical short-range order.

Ab initio informed yield criterion across body-centered cubic transition metals

Baptiste Bienvenu et al.

Summary: This paper presents a yield criterion that can predict the yield stress and active slip systems in bcc transition metals. It is based on ab initio calculations of screw dislocation glide properties and is compared with experimental results, accurately describing the plastic behaviors observed in different metals.

Theory of solid solution strengthening of BCC Chemically Complex Alloys

S. I. Rao et al.

Summary: An analytic model for substitutional solid solution strengthening in BCC CCAs based on a/2<111> screw dislocation mobility is developed and presented. Different strengthening mechanisms are observed at different temperatures, requiring modifications to existing models to apply to refractory CCAs.

Chemical short range order strengthening in BCC complex concentrated alloys

E. Antillon et al.

Summary: Atomistic methods were used to anneal two BCC chemically complex alloys to evaluate the effect of chemical short-range order on alloy strength. It was found that annealing led to a softening of the BCC quaternary alloy but had minimal effect on solid solution strengthening in the ternary alloy. Results were modeled using an extension of the Suzuki model of substitutional solid solution strengthening, with good agreement between the model results and direct atomistic simulation data.

Atomistic simulations of dislocation mobility in refractory high-entropy alloys and the effect of chemical short-range order

Sheng Yin et al.

Summary: The presence of short-range order influences the mobility of dislocations in high-entropy alloys, with edge dislocations being enhanced and double-kink nucleation in screw dislocations being reduced. A cross-slip locking mechanism is observed for the motion of screws, providing extra strengthening for refractory high-entropy alloy system.
