Original Abstract

In directly keyhole electron beam welding of Ti/Al alloys the heterogeneous interfacial reactions were found in the weldments. The intermetallic brittle phases (e. g. Ti3Al) formed at the weld joint and affected mechanical properties. To improve the homogeneity, change of electron beam offset and using of filler metal were studied. The effects of attempts were investigated by structural analysis, analysis of chemical composition and by hardness measurement. The results indicate that the modification of welding process from directly electron beam welding to electron beam welding-brazing process was more beneficial than using of filler metal.
