As the demand for materials that can survive extreme environments reaches an all-time high, High Entropy Alloys (HEAs) have emerged as a transformative solution of future exploration. Departing from the traditional "one-base-element" metallurgy concept, HEAs leverage vast compositional spaces and unique lattice distortions to achieve properties once thought mutually exclusive.

This session aims to bridge the gap between fundamental alloy design and industrial scalability. We invite researchers to present breakthroughs in High Entropy Alloy (HEAs) and/or Multi-Principal Element Alloys (MPEAs), focusing on how these complex systems challenge our current understanding of the topic.

Key points of interest can include (among others) the following topics:

• Processing Challenges and Additive Manufacturing (AM) Integration
• AI and High-Throughput Discovery Methods (ML, CALPHAD etc.)
• Microstructural Evolution and Stability Trends
• The "Cocktail Effect" in Extremes
• Mechanical Property Synergies
• Surface Degradation Phenomena and Environmental Resilience
