    | Abstract Scope | Multi-principal element alloys (MPEAs) have attracted widespread interest due to their exceptional properties at multiple length-scales. Small-scale mechanical behavior of several single-phase and complex MPEAs was investigated. Strain rate sensitivity and strain gradient plasticity was measured for fundamental understanding of deformation mechanism. The nano-mechanical behavior and twinned microstructure was explained by low stacking fault energy. Phase-specific response was evaluated for multi-phase MPEAs using micro-pillar compression and micro-cantilever bending tests to explain their simultaneous high strength and good ductility. |
