Abstract

Titanium is perspective construction material. Titanium and its alloys are perspective for application in many industries of modern technique: aviation, space-rocket technique, chemical engineering and etc. In some cases titanic alloy is the only material that is used to make the equipment or constructions able to work in extreme conditions. The heat-exchangers operating in corrosion environment, nitric and sulphuric acids are made from titanic alloys. In titanic heat-exchangers working in 65% aquafortis solution with the temperature of 160 ° corrosion speed goes down 60 times as compared to heat-exchangers from stainless steel. In addition, the high inoxidizability of titanium allows the thickness reducing of the heat-exchanger wall to the minimum. Titanium is mostly used in aviation, rocket production and other industries of technique, where specific durability has an important value. For the temperatures interval 300-600 ° C the titanium alloys have a high value of specific durability at temperatures below 300 ° C as compared to aluminium alloys and iron and nickel alloys at temperature above 600 ° C . In aircraft designing the aim is to get the most lightweight construction in combination with high durability. In an industrial scale titanic alloys were first used in the constructions of aviation engines. Application of titanium in the constructions of ramjets allows to decrease considerably their deadload, disks, compressor shoulder blades, detail of fastening, aviation turbo-engine housing are made from titanium alloys.
