TL5 titanium circle, rod, sheet
Foundry titanium alloy TL5 () Ti-4,25Al-2V). A CRI «Prometheus» for use in marine environments. It features corrosion resistance in seawater. Modern technologies allow producing titanium alloy products of any type. Alloy titanium alloys are indispensable in the production of valves for various applications. Foundry titanium alloy TL5 indispensable in the production of tyazhelogruzhenyh parts of turbogenerators, in the manufacture of propellers, welded structures
Advantages of titanium alloy TL5
|Alloy||general characteristics||Technological properties||application|
|TL5||It has greater strength than TL3, but lower ductility.||It has good casting properties and good welds.||Heavily laden with details of turbine generators, propellers, welded construction.|
Low density titanium facilitates designs weight compared to steel in half, leading to a decrease of the load bearing components in the mechanisms. As a consequence of increases service life of equipment. Valuable resistance of casting titanium alloys against cracking and crevice and intergranular corrosion. Titanium corrosion rate less than 0.002 mm / year. Rack titanium alloys in fresh and sea water, to the action of atmospheric moisture and soil, they are stable when in contact with acids, in the medium oil, petroleum products and natural gas in boiling ammonia solution and aggressive industrial atmosphere.
A number of studies demonstrated the possibility of improving the mechanical properties of shaped castings by forming heat treatment method biplastinchatoy structure. Its basis is α-wide plates with layers of transformed β-phase. Heat treatment giving biplastinchatuyu structure includes: 1) annealing at temperatures of α + β-region (the width of beta interlayer increases) and 2) the subsequent cooling, leading to the isolation of a β-phase thin α-plates of different orientations, that effectively inhibits the transfer slip through the plate-like structure.
For formation of the lamellar structure of parts produced by investment casting, followed by gas-static treatment, they were heated at 1050 ° (β-region) and cooled at 1 ° C / min ,. To achieve biplastinchatoy structure samples were heated at 880 ° C and cooled at rates from 15 to 8000 ° C / min. With increasing cooling rate the thickness of the transformed β-layer was increased. In the final step, all samples were aged at 500 ° C for 24 hours to form fine particles of α-2 phase.
Foundry TL5 titanium alloy made according to OST 5R.9071−88. With increasing the cooling rate of casting titanium alloys the yield strength increases, resistance increases and low-cycle fatigue.
To eliminate the hidden marriage, the casting is subjected to hot isostatic pressing, which brings them closer to the crystal structure of wrought iron. A mandatory external examination, chemical composition analysis, inspection of mechanical properties of castings. Such quality control methods such as X-ray, gamma-Skopje, ultrasonic flaw detection, fluorescent (liquid-penentratny) control. Casting may also be tested hydraulic or pneumatic pressure.
