While the Block 30/35 F-22 remains one of the USAF's top priorities, the service believes the Block 20 aircraft is obsolescent and unsuitable even for training F-22 pilots and that upgrading them to Block 30/35 standards would be cost-prohibitive at $3.5 billion. [5] [260]
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine .
Ti-6Al-4V (UNS designation R56400 ), also sometimes called TC4, Ti64, [ 1] or ASTM Grade 5, is an alpha-beta titanium alloy with a high specific strength and excellent corrosion resistance. It is one of the most commonly used titanium alloys and is applied in a wide range of applications where low density and excellent corrosion resistance are ...
The Alfa class, Soviet designation Project 705 Lira ( Russian: Лира, meaning "Lyre", NATO reporting name Alfa ), was a class of nuclear-powered attack submarines in service with the Soviet Navy from 1971 into the early 1990s, with one serving later with the Russian Navy until 1996. They were among the fastest military submarines ever built ...

A common reduced titanium oxide is TiO, also known as titanium monoxide. It can be prepared from titanium dioxide and titanium metal at 1500 °C. [ 4] Ti 3 O 5, Ti 4 O 7, and Ti 5 O 9 are non-stoichiometric oxides. These compounds are typically formed at high temperatures in the presence of excess oxygen. [ 5][ 6] As a result, they exhibit ...
Fire Man was designed for waste management work, particularly incineration, and can withstand temperatures up to 8000 °C and generate heat. He attacks by surrounding himself in a circle of flame and shooting balls of fire; in Mega Man: Powered Up, his weapon is severely limited if the flames atop his head are extinguished.
Titanium dioxide nanoparticles, also called ultrafine titanium dioxide or nanocrystalline titanium dioxide or microcrystalline titanium dioxide, are particles of titanium dioxide ( TiO2) with diameters less than 100 nm. Ultrafine TiO2 is used in sunscreens due to its ability to block ultraviolet radiation while remaining transparent on the skin.
