Mechanisms of High Temperature Degradation of Thermal Barrier Coatings. [PDF]
, 2009 Thermal barrier coatings (TBCs) are crucial for increasing the turbine inlet temperature (and hence efficiency) of gas turbine engines. The thesis describes PhD research aimed at improving understanding of the thermal cycling failure mechanisms of ...

Consolidation Efficiency of Noncompact Alloys by Diamond Burnishing
Наука и техника, 2019 Active use of parts synthesized while using additive technologies from powders is limited due to presence of residual porosity contributing to a decrease in strength, ductility, fracture toughness, crack resistance, workability by cutting, as well as ...

Thermal reaction of Al/Ti bilayers with contaminated interface [PDF]
, 1989 We have studied some new aspects of thermal reactions in Al/Ti bilayers in which the interface is purposely contaminated with oxygen. After annealing at a temperature of 460 °C, an Al_3Ti compound forms at the interface, moreover some Al diffuses through

Titanium honeycomb structure [PDF]
, 1972 A brazed titanium honeycomb sandwich system for supersonic transport wing cover panels provides the most efficient structure spanwise, chordwise, and loadwise. Flutter testing shows that high wing stiffness is most efficient in a sandwich structure. This

Microstrain Analysis of Titanium Aluminides [PDF]
Materials Science Forum, 2010 The aeronautic and automotive industries have shown a renewed interest in TiAl based alloys. The main reasons for such an interest are their low density (~3,8g/cm3), a good stiffness and a high strength for temperatures up to 750°C. However, these alloys exhibit, in their polycrystalline form, a poor ductility at room temperature with widely scattered ...

Oxidation behavior of titanium aluminides
Le Journal de Physique IV, 1993 Results from an ongoing study of the high temperature oxidation of intermetallic compounds in the Ti-Al system are presented. The oxidation behavior of alloys based on TiAl (γ) has been found to be extremely complex depending on temperature and atmosphere composition.

Mechanical properties of coated titanium Beta-21S after exposure to air at 700 and 800 C [PDF]
Mechanical properties of Beta-21S (Ti-15Mo-3Al-2.7Nb-0.2Si, wt percent) with glass, aluminide, and glass-on-aluminide coatings less than 3-micron thick were studied. Coatings were deposited by sol-gel processing or electron-beam evaporation onto 4.5-mil (

Method of protecting a surface with a silicon-slurry/aluminide coating [PDF]
, 1982 A low cost coating for protecting metallic base system substrates from high temperatures, high gas velocity oxidation, thermal fatigue and hot corrosion is described. The coating is particularly useful for protecting vanes and blades in aircraft and land
