Development of reliable joints between JLF-1 steel and stainless steels are required. As known, different methods for joining various materials are assumed to be used for the construction of International Thermonuclear Experimental Reactor first wall, blanket, divertor and reactor vessel. Recently, joints technology development of JLF-1 steel (Fe-9Cr-2W-V-Ta) and Stainless steel(STS304) have been investigated for diffusion bonding, brazing, roll bonding, explosive bonding and hot isostatic pressing. On the other hand, a friction welding is one of the most popular welding method for joining between different materials such as a tube. Not only the development of optimizing of friction welding with more reliability and more applicability but also the development of in-process real-time weld quality evaluation technique by acoustic emission for dissimilar friction welding of nuclear reactor component(JLF-1 and STS304) were carried out.

Reduced activation ferritic steel, JLF-1 steel (Fe-9Cr-2W-V-Ta), is one of the promising candidate<br/> materials for fusion reactor applications. Fracture toughness (JIC) and tensile tests were carried out at<br/> room temperature and elevated temperature (400 ℃). Two types of CT specimen were prepared to<br/> examine the effect of rolling direction on the fracture toughness of JLF-1 steel. Four types of tensile<br/> specimen were also prepared to investigate the property by the rolling direction and welding. The<br/> Micro Vickers hardness was measured at various distances of a cross section of the TIG joints of<br/> JLF-1 steel according to the heating history of each position. Finally, the fracture surface was observed<br/> by scanning electron microscopy (SEM).
