Development of reduced activation steels for fusion power plant
- Development of reduced activation ferritic/martensitic (RAFM) steels with unique chemical compositions which have enhanced mechanical properties such as tensile and impact properties, creep, fatigue, etc. and high resistance to neutron irradiation and swelling
- Unique reduced activation ferritic/martensitic steels with Ti
- Improved balance of strength and impact toughness
Austenitic heat-resistant steels for next-generation energy plants
- Optimum composition and process condition are designed to develop advanced austenitic heat-resistant steels for high-temperature applications over 650℃ in next-generation energy plants of high efficiency.
- Modeling and prediction of creep properties using artificial neural network method.
- Optimization of Mn content for the maximum oxidation-resistance of TP304H series alloy
- Development of original alumina-forming alloys (AFA) with superior performances: superior creep- (+62%) and oxidation-resistance (+15%) to the original AFA
