Joints of copper sheets with a thickness 0.8 mm were produced by ultrasonic welding. To assess the quality joints, tensile lap-shear strength, area fraction bonding, distributions normal strains in cross sections welded samples, linear weld density at magnification ×1000, and microstructure microhardness samples analyzed. It was proved that arrangement microbonds length gaps joint zones significantly depended on local caused penetration tool ridges under clamping pressure. Joint regions more...
Structural methods for controlling the properties of a layered material (LM) based on Ti-6Al-4V alloy are presented in this work. The materials were manufactured by diffusion bonding. They consist seven and thirteen sheets thickness about 1.5 0.8 mm, respectively. Two assembling used: one case, they stacked relative to each other so that rolling direction (RD) them coincided (LM type 1), other, did not match 2), angle between RD neighboring was 0 90 degrees, It found prismatic texture...
The mechanical behavior at shock loading of samples from titanium alloy VT6 with different structural: coarse-crystalline lamellar morphology phases (CC), microcrystalline globular (MC), nanostructure (NS) is analyses. Results tests showed that in the CC and MC structures have higher level impact toughness comparison nanostructure. With reduction size structural components work crack nucleation raises on % 55, propagation reduces 70. Impact decreases 20. picture fracture reflects...
The mechanical behavior is analyzed at shock loading of the structural composite received by pressure welding alternating sheets VT6 titanium alloy with lamellar and globular structures. Comparative researches layered material consisting structure showed that use leads to decrease impact toughness samples in which crack propagations simultaneously through all layers. lowered these caused lower work propagation structure. <br />
Abstract The results of studies on the mechanical behavior a Ti-6Al-4V laminated material obtained by diffusion welding are analyzed. It is shown that impact layered depends many factors including interface defects, orientation notch tip relative to interface, number and microstructural state layers their crystallographic texture.

Рассмотрено влияние пор на механические свойства образцов, полученных сваркой давлением листовых заготовок титанового сплава ВТ6.Традиционно считается, что поры в зоне твердофазного соединения являются дефектами, снижающими показатели конструкционной прочности.Результаты испытаний сдвиг свидетельствуют о снижении сдвиговой прочности с увеличением протяженности
The main point of successful manufacture metallic composites by direct bonding dissimilar materials is achieving a homogeneous interface bonding. Two different types deformation techniques for fabrication metal were investigated. first one was developed on the basis high pressure torsion associated with energy impact material where part involved can be dissipated via non equilibrium phase transition realization. This due to shear deformations allows not only form nanostructure, but also bond...
The paper presents the results of studies on mechanical behavior under impact and tensile loading a Ti-6Al-4V three-layer material obtained by diffusion bonding at 800°C. Diffusion is process that integrates one with another pressure temperature below melting points materials. alloy particularly interesting for aerospace structures, ballistic armor sports equipment manufacturing. Predominantly single spherical pores are present in joint zone; chains extremely rare. static properties laminate...
In the manufacture of three-layer corrugated structures made titanium alloys by diffusion bonding followed superplastic forming, stop-off materials are used. The use material makes it possible to selectively connect sheet blanks with each other and, as a result, get hollow structure an internal set stiffeners in form corrugation. effect based on boron nitride and yttrium oxide mechanical properties alloy Ti-6Al-4V is studied. Special attention paid influence quality solid-phase joints...
