dc.description.abstractThe new technologies of the diffusion vacuum welding (DVW) of aluminum alloys and titanium alloys have been considered. The aim of the paper is to study the special features of the processes of the formation of the structure and phases in the diffusion vacuum welding of an aluminum alloy with a titanium alloy, as well as the establishment of scientific foundations of obtaining welded joints by optimizing their structure and the phase composition. For the study of diffusion and recrystallization processes at the DVW, the specimens of AMg6 and WTi6 were welded without the AD1 interlayer and with its application. The metallographic studies were performed using an Auger microprobe equipped with an energy dispersive X-ray spectrometer of the INCA system on the sections of welded joints produced by ion etching. Due to the negative impact of magnesium, it is not possible to obtain a welded joint of the WTi6 titanium alloy with the AMg6 aluminum alloy without the aluminum interlayer. The initial AMg6 structure of the banded type is converted into grains of different sizes and shapes in the process of welding. At the area of the joint with the interlayer in the AMg6 alloy they have more equiaxed shape and smaller dimensions. In the AD1 alloy, there are oxide type globular inclusions of the production origin. The structure of the WTi6 titanium alloy does not change during the welding process and consists of the primary grains elongated along the rolled metal of the predominant form factor 2. The secondary structure is the α-phase plates with layers of the β-phase along the boundaries of the plates and primary grains. The results of the study are of interest in making products for the aviation and space industries. They are to meet the stringent requirements for preservation of the initial size of the details, which is only possible if there are no notable deformations. The determined regularities allowed developing the welding technology to obtain high-quality welded joints using the diffusion vacuum welding. The number of areas with defects is no more than 5 % of the total area of the joint, where the intermetallic compounds are not formed at the junction of the interlayer and the titanium alloy.rus
