Summary: One of the key factors in designing high-performance alloys is understanding their incipient behavior. This study uses molecular dynamics simulations to observe in real-time the atomic scale evolutions of multi-principal element alloys (MPEAs) during nanoindentation incipient yielding. The effects of lattice distortion and chemical short-range ordering on the initiation of plasticity in body-centered cubic MPEAs are investigated. The results show that lattice distortion and chemical short-range ordering can boost embryo nucleation, acting as precursors for dislocation nucleation.
