Application of Electron Beam Welding Technique for Joining Ultrafine-Grained Aluminum Plates

Abstract The present study is the first attempt to join ultrafine-grained materials by electron beam welding. aim of was check feasibility and effectiveness this type welding for thermally unstable materials. results obtained are high interest, while did cause a decline in mechanical properties, were comparable those using solid-state welding, but with significant advantage narrower fusion- heat-affected zones.
