Crystal structure responses of corundum-type structures (α-Al 2 O 3 and α-Fe 2 O 3 ) under dynamic acoustic shocked conditions and their comparison between static high-temperature and high-pressure conditions: implications on volume-pressure-related phase transition types

Key Points

• The central aim is to examine how α-Al2O3 and α-Fe2O3 respond structurally under different shock and pressure conditions.
• Investigated structural responses of α-Al2O3 and α-Fe2O3 under dynamic acoustic shock conditions.
• Compared results with static high-temperature and high-pressure conditions.
• Analyzed thermal conductivity values based on a superheating approach.
• α-Al2O3 nanoparticles show high structural stability under acoustic shock.
• Differences in structural responses are noted between dynamic and static conditions.
• Thermal conductivity plays a significant role in understanding the stability of the materials.
