Avalanche-like Plasticity in Complex Concentrated Alloys: A Review Across Scales
This review examines avalanche-like plasticity in Complex Concentrated Alloys (CCAs) by investigating how intermittent deformation occurs across different scales. The research identifies that complex mechanisms like dislocation avalanches and twinning are scale-dependent, meaning their behavior changes from microscopic events to macroscopic stress serrations. It concludes that chemical disorder and microstructure critically control how these plastic events organize.
