Effect of electron beam welding current variations on the microstructure and mechanical properties of Nb-1Zr advanced alloy

The effect of electron beam welding current changes on the microstructure and mechanical properties of the Nb-based alloy has been investigated. The electron beam welding was applied with 4 different values for electric current 20, 24, 30 and 35 mA on 3 mm thick plates. The aspects including different welding regions, geometry and depth of welding penetration, as well as the effect of heat input on the mechanical properties are investigated. The...
