| Abstract Scope |
The need for advanced materials in nuclear reactors has spotlighted ferritic oxide dispersion strengthened steels for their excellent high-temperature strength, irradiation resistance, and corrosion tolerance. However, conventional powder metallurgy routes such as mechanical alloying often involve multiple processing steps which are complex, time consuming and costly. Additionally, such techniques are often associated with microstructural inhomogeneities and defects. The current study introduces a novel approach of using novel friction extrusion process to extrude fully consolidated tubes of ~1 mm wall thickness through intense shear at reduced temperatures (1000ºC). As proof of concept, pilgering was applied to fabricate thin-walled cladding tubes of ~0.5 mm wall thickness from the extruded tubes with uniform cross-sections. Microstructural and mechanical characterization confirmed a high dispersion of nanometric oxides (>1020/ m3) in both the extruded and pilgered tubes along with enhanced mechanical properties, comparable to those achieved via conventional methods. |
