Zhujin Technology Secures High-Entropy Alloy Powder Patent CN121945779B: Digital Twin-Optimized Production Achieves 1200-1300 MPa Yield Strength and ≥12% Elongation
2026-09-18
Zhujin Technology (835492) has been granted an invention patent for "A High-Entropy Alloy Powder and Its Preparation Process," under announcement number CN121945779B, with the grant date of September 18, 2026. Technical highlights: The preparation process is optimized through multi-scale simulation and digital twin technology—molecular dynamics is used to design the composition of CoCrFeNiMn-based high-entropy alloys, acoustic emission combined with CNN monitors the preparation process, defect engineering introduces 5-10 nm Y₂O₃ internal oxidation dispersed phases, and spark plasma sintering with intelligent triggering and Bayesian optimization is employed to achieve a powder yield strength of 1200-1300 MPa and elongation ≥12%, representing a 20-30% strength improvement over conventional processes. Significance: High-entropy alloy powders are candidate structural materials for extreme operating conditions in defense, nuclear energy, and ultra-low temperature applications. The digital twin-driven preparation process provides a replicable engineering pathway for domestic high-entropy alloy powders to transition from the laboratory to mass production.
