The article presents the results of studies on forecasting compressive strength and density aerated ash concrete. A theoretical review was conducted variability cellular concretes when selecting their compositions. series experiments to study dynamics changes in non-autoclaved gas-ash concrete during initial stages hardening under natural conditions after thermal treatment select a composition specified quality. It revealed that it is possible control both at early forecast these parameters...
Application of the conventional superplasticity (SP) allows producing unique hollow structures. One remarkable example is titanium blade air engine fan produced by Rolls-Royce. However, high temperature Ti-6Al-4V alloy processing (~ 927 °С) limits wide industrial application SP. On base experimental data examples superplastic forming (SPF) structures for aerospace out ultrafine-grained (UFG) VT6 (Ti-6Al-4V) using an effect low SP are demonstrated. We used two-phase in VSMPO, Verhnyaya Salda,...
Application of the conventional superplasticity (SP) allows producing unique hollow structures. One remarkable example is titanium blade air engine fan produced by Rolls-Royce. However, high temperature alloys processing (~ 927 °С) limits wide industrial application SP. The solution mentioned issue can be found through low-temperature Ti-6Al-4V alloy with ultrafine grain structure at range 600 800 °С has enough ductility resources for superplastic forming (SPF) parts complicated shape....
Superplastic forming of a three-sheet structure is considered. The focus on overcoming the main disadvantages process manufacturing such structures by means SPF/DB technique including high temperatures treatment and formation folds outer surface article manufactured. application ultrafine-grained sheets titanium alloy Ti-6Al-4V has been analyzed in order to avoid these disadvantages. Various combinations use microcrystalline as skin core are considered finite element analysis. standard power...
Superplastic forming of thin sheet corrugated structures is special interest in developing aircraft technologies new generation. The manufacture such includes pressure welding a package three blanks, consisting two outer skin sheets and one inner core blank. stop-off coating applied to the surfaces before welding. During superplastic package, take form die cavity, while stretches between skins stiffeners. One main problems manufacturing three-layer known be formation folds on surface skins....
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...

The formability of the novel Ti-1.5Al-1.5V-2.75Fe-3.0Mo-0.25Ni-0.1B alloy and commercial Ti-6Al-4V at 700°С was evaluated in present study. Experiments have demonstrated possibility superplastic forming both alloys with a fine-grained microstructure 700°C constant argon gas pressure p = 2 MPa. However, time for only few minutes (τ 235 s), while it amounted almost 2.5 hours 8700 s). better compared to one is good agreement results computer simulations performed earlier mainly due an increased...
