Résumé :
In this Work, the effect of the TIG Welding process on the Morphology and mechanical behavior of α grain boundary (α-GB) phase appearing in TA6V welds are investigated. Different morphologies are observed depending on the pulsed frequency parameter, namely, the Zig-Zag morphology, the saw-teeth morphology and the normal continuous layer. The micro-hardness of each morphology has been measured and discussed.
