Creep strain modeling for alloy 690 SG tube material based on modified theta projection method

Nuclear Engineering and Technology, 2022
During a severe accident, steam generator (SG) tubes undergo rapid changes in the pressure and temperature. Therefore, an appropriate creep model to predict a short term creep damage is essential.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Embrittlement of Hydrogen-Charged Alloy 690 Single Crystal.

Journal of Society of Materials Engineering for Resources of Japan, 1995
The effects of charging temperature and time on the embrittlement of cathodically hydrogen-charged specimens were investigated by tensile test and scanning electron microscopic studies on Alloy 690 single crystals with ‹100› tensile axis. Many cracks on the specimen surface were observed along {100} traces.
