“…Major problem of reliability increase for aircraft and gas-turbine engines is prevention the risk of breakage of most critical constructional elements [1][2][3][4][5]. Toughening of requirements regarding operability of critical purposes welded constructions on base of titan alloys may be satisfied by high quality of welded joints.…”

Analysis of fracture surfaces morphology of material of welded joints of Ti-TiB system alloys and (α + β) Тi alloy, obtained by electron-beam welding under various technological modes, is carried out. Parameters alterable were the electron beam displacement velocity and initial temperature of the parts welded. Prevalent effect of boron phase on fracture character of Ti-TiB system alloys and possibility of ductility increase both Ti-TiB system and (α+β Тi alloy, due to thermal effect action, is shown.

“…The process of direct laser deposition is one of the types of additive manufacturing technologies that allows for the production parts of complex geometric shape [1] from various materials [2][3][4], due to melting and crystallization of the filler material under the action of laser radiation directly in the processing zone, in situ. The deposited parts can be divided into three groups: thin-walled parts [5] deposited in one pass, thick-walled parts [6] with a width of several passes and parts manufactured in a combined way.…”

Direct laser deposition (DLD) is a promising additive technology that allows for the rapid and cheap production of metal parts of complex geometry in various sectors of mechanical engineering. Thick-walled metal structures occupy a significant part in mechanical engineering. The purpose of this study was to develop and test an algorithm for predicting the geometry of deposited multi-pass walls. To achieve this goal, the main interrelated processes involved in the formation of a multi-pass wall were described—the process of laser radiation propagation, the process of heat transfer and the process of bead formation. To construct the calculation algorithm, five characteristic types of beads are identified. For these five types, the features of the bead formation and the features of the laser radiation intensity distribution are described. The calculated data were verified. A good match of the calculated data with the geometry of the deposited walls from AISI321 steel, Inconel718 and Ti-6Al-4V alloys was obtained.

“…Lastly, the required geometry of the metal component can be produced layer by layer. [4,6,7] DLD is represented in various industry areas which is one of the reasons why it is a very attractive field of study. One of them is the aerospace field where a great amount of metal components with complex shapes are made.…”
