Amorphous/Crystalline Dual-Phase HEA Film

Lower creep than coarse-grained

For high-temperature load-bearing and precision components, the dual-phase structure suppresses creep deformation significantly via amorphous phase diffusion and interfacial dislocation control, outperforming monophase and coarse-grained counterparts.
