Electron Beam Welding (EBW) is used in various industrial applications for joining dissimilar metals due to its accuracy and good quality joints. International Thermonuclear Experimental Reactor (ITER) is the first experimental fusion power generating reactor in India. It uses a host of metals and alloys like Ti-6Al-4V, Ni-Al bronze and a special copper alloy (CRZ). This investigation aims to study the metallurgical and mechanical aspects of CRZ alloy and its EBW joint with a dissimilar metal like Nickel and stainless steel. Characterization includes material composition and effect of heat-treatment. The CRZ alloys were solution annealed at the temperature of 980 degrees C for 15 minutes and then aged at 460-480 degrees C for 4.5 hrs. The EBW welded joints were fabricated with CRZ-CRZ, CRZ-Ni and Ni-SS combination. The microstructure and mechanical properties were analyzed.
