First-principles guided design and high-pressure sintering of polymer-derived high-entropy carbides with superior hardness and modulus

Key Points

• Superior hardness and modulus were identified in high-entropy carbides compared to traditional materials—showing significant improvements.
• The analysis indicates a hardness increase to 40 GPa, with a modulus exceeding 450 GPa, enhancing structural applications.
• First-principles guided design coupled with high-pressure sintering maximizes the material properties for advanced applications.
• Potential applications may transform industries focusing on hard materials; the findings point to high-performance uses.
