In this work, we study loop dynamics at room temperature across three refractory multi-
principal element alloys (RMPEAs) using a phase field dislocation dynamics simulation …

Refractory multiprincipal element alloys (RMPEAs), a relatively new class of alloys, are
attractive not only for ultrahigh strengths but also for low rates of decay in strength with …

The dependence of dislocation mobility on temperature, stress, and alloy composition is a
key to describing plastic deformation in metals. A special case is the plasticity of body …

In this work, we employ a phase field dislocation dynamics technique to simulate dislocation
motion in body centered cubic refractory metals with diffusing interstitials. Two distinct …

In the pursuit of developing high-temperature alloys with superior ability to fulfill the
performance requirements of next-generation energy and aerospace demands, integrated …
