| Abstract Scope |
Solid phase processing is an innovative manufacturing technique that enables the fabrication of high-performance advanced nuclear cladding materials with high efficiency and low energy consumption. During SPP, severe shear deformation and elevated temperatures – below material’s melting point – generated through plastic deformation and friction facilitate accelerated solid-state diffusion and dynamic recrystallization, enabling high-performance cladding production in a single step. To better understand the intricate process-structure-property relationships in SPP, an ICME framework has been developed. This multiscale framework uses smoothed particle hydrodynamics (SPH) to predict thermomechanical responses at the macroscale, which serve as inputs for a mesoscale phase-field and crystal-plasticity (PF-CP) model to simulate microstructure evolutions and subsequent material property changes. To enhance computational efficiency, an AE-LSTM machine learning model is integrated into the SPH modeling process. The framework is applied to friction extrusion of oxide dispersion-strengthened (ODS) steels to help obtain superior strength and corrosion resistance under harsh environments. |
