In recent years, machine learning potentials (MLPs) have become indispensable tools in physics, chemistry, and materials science, driving the development of software packages for molecular dynamics (MD) simulations related applications. These packages, typically built on specific frameworks, such as TensorFlow, PyTorch, or JAX, face integration challenges when advanced applications demand communication across different frameworks. The previous TensorFlow-based implementation DeePMD-kit...
In the present work, irradiation hardening of a low-copper reactor pressure vessel steel (Chinese A508-3) is studied. Specimens RPV were irradiated with high-energy Fe ions at terminal cyclotron low temperature around 173 K to two damage levels 0.15 and 0.21 dpa. Micro Vickers hardness was measured from specimens after stepwise thermal annealing temperatures 300, 573, 623 673 K, respectively. The both doses exhibit obvious hardening. With increase temperature, decreases monotonically....
Micro-structural characteristics and electrical properties of an n-type GaN epilayer on Al2O3 irradiated by 290-MeV 238U32+ ions to various fluences were investigated using atomic force microscopy (AFM), scanning electron (SEM), high-resolution X-ray diffraction (HRXRD), Raman scattering spectroscopy. AFM images show that the nano-hillocks generated, diameter density nano-hillocks, increase obviously with increasing ion fluence, accompanied in surface roughness. SEM display Al, O, C elements...
In the present work, irradiation hardening behavior of a Chinese low-activation ferritic/martensitic steel CLF-1 candidate to fusion reactor blankets is studied. Specimens were irradiated with high-energy 14N and 56Fe ions at terminal cyclotron three successively increasing damage levels 0.05, 0.1 0.2 dpa about -50 oC. Energy incident was dispersed decreasing 11 grades by using an energy degrader, thereby generating atomic displacement plateau in specimens from surface depth 25 μm, which...
