“…[23,25,[30][31][32][33] The manufacturing of EXW clads requires a number of parameters to be controlled, such as the collision angle, impact velocity, detonation pressure, and geometry, with respect to the type of bonded materials. [28,[34][35][36][37][38][39] However, the problem becomes even more complicated when more than only one interface is obtained. Therefore, in this manuscript, the simplest case with only two interfaces obtained in three-layered Al/Ti/Al clads is discussed.…”

The microstructure and phase composition of Al/Ti/Al interfaces with respect to their localization were investigated. An aluminum-flyer plate exhibited finer grains located close to the upper interface than those present within the aluminum-base plate. The same tendency, but with a higher number of twins, was observed for titanium. Good quality bonding with a wavy shape and four intermetallic phases, namely, TiAl 3 , TiAl, TiAl 2 , and Ti 3 Al, was only obtained at the interface closer to the explosive material. The other interface was planar with three intermetallic compounds, excluding the metastable TiAl 2 phase. As a result of a 100-hour annealing at 903 K (630°C), an Al/TiAl 3 /Ti/TiAl 3 /Al sandwich was manufactured, formed with single crystalline Al layers. A substantial difference between the intermetallic layer thicknesses was measured, with 235.3 and 167.4 lm obtained for the layers corresponding to the upper and lower interfaces, respectively. An examination by transmission electron microscopy of a thin foil taken from the interface area after a 1-hour annealing at 825 K (552°C) showed a mixture of randomly located TiAl 3 grains within the aluminum. Finally, the hardness results were correlated with the microstructural changes across the samples.

“…The possibility of joining steel with aluminum alloy by welding was realized with the use of Al/Fe explosively welded transition joints. The plates were welded in a parallel arrangement in which the flyer plate was at a constant distance from the base plate [ 32 , 33 ]. Testing plates were produced using the explosive material at a detonation velocity in the range of 1950–2050 m/s.…”

The study presents an analysis of S355J2+N steel and AA5083 aluminum alloy welded structural joints using explosion welded transition joints of reduced thickness. The transition joint thickness reduction significantly hinders the welding of the joints due to the risk of damage to the Al/steel interface as a result of the high temperatures during welding. In the previous article, the strength of the transition joint was analyzed but ship structures, apart from static loads, are subjected to many different cyclical loads. Welded structural joints are analyzed to determine the welding influence on the fatigue life and fracture type of the transition joints. The results of the fatigue tests show that the fatigue damage in the specimens occurs in the aluminum welded joint, and not in the explosively welded joint. The damage obtained was characteristic of cruciform welded joint specimens and both types of root and toe damage occurred. Based on the obtained results, fatigue curves for the joint were determined and compared to the fatigue curves for the AA5083 base material. The experimental fatigue curve was also compared with the design curve for welded aluminum structures from Eurocode. The conducted analysis showed the possibility of using Al/steel explosion welded transition joints of reduced thickness to transfer cyclical loads.

“…Mechanizm powstawania powłoki polega rozcieraniu materiału czoła narzędzia na powierzchni ceramiki. Literatura przedmiotu wskazuje że podczas spajania w stanie stałym możliwe jest uzyskanie trwałych złączy materiałów skrajnie różniących się właściwościami zarówno fizycznymi jak i cemicznymi [1÷5, 12,13]. W celu uniknięcia utlenienia tytanu obszar roboczy otoczono cylindryczną barierą do wnętrza której dostarczano argon z natężeniem przepływu 5l/min.…”

W pracy przedstawiono wybrane właściwości tytanowej powłoki metalizacyjnej wytworzonej na ceramice AlN metodą tarciową opierając się na mechanizmie powstawania połączenia, w którym energia tarcia kinetycznego jest bezpośrednio zamieniana na ciepło i dostarczana w ściśle określonej ilości do obszaru powstającego połączenia między warstwą a podłożem. W artykule scharakteryzowano tytanową powłokę metalizacyjną pod względem budowy fazowej, właściwości metalograficznych, morfologii powierzchni, struktury stereoskopowej powierzchni oraz grubości.
