Influence of post weld heat treatments on structure of electron beam welds of Ti-6Al-4V alloy

Popis výsledku v původním jazyce

Electron beam (EB) welding belongs among the most appropriate welding methods for joining of titanium alloys mainly due to the advantages which are resulting from the using of this method. The required presence of vacuum during EB process may lenghten the overall processing time, but also provide protective enviroment which is necessary for the quality welds of titanium alloys. The precision control of EB welding process allows irradiating the workpiece by EB with high density of energy. This reduces the quanitity of heat input to the material and results in deep and narrow welds with the minimum heat affected zone. In many materials this can lead to the formation of significant thermal stresses during solidification of weld metal which can promote thenucleation of cracks. The post-weld heat treatment (PWHT) may be used to eliminate these stresses. In this article the microstructure and microhardness of EB welds of Ti-6Al-4V alloy is studied. The welds are evaluated in the as-welded s
