High‐Throughput Data Generation and Transfer Learning Enabled Microstructure‐Property Integrated Design of Nickel‐Based Powder Metallurgy Superalloy
) alloy, designated USTB-PM750. This alloy exhibits a yield strength of 1138 MPa and a creep life of 141 h to 0.2% strain at 750°C under 480 MPa. Microstructural analysis reveals that its superior performance stems from a low stacking-fault energy, which promotes the formation of stacking faults and microtwins. These defects subsequently evolve into dense networks of Lomer-Cottrell locks, further reinforced by solute-segregation-induced local phase transformations. This approach significantly improves alloy design efficiency and offers a promising high-performance candidate material for turbine-disk applications in advanced aero-engines.
