General characteristics

Titanium alloys klassificeret configuration of crystal lattices: α-lattice in the form hexahedron), β respectively, α+β mixed state. Titanium alloy VT3−1 belongs to the alpha+beta alloy contains the following alloying elements.

Aluminium	Molybdenum	Copper	Iron	Silicon
6,3%	2,5%	A 1.5%	0,5%	0,3%

Aluminium is the main alloying element in titanium alloys, it is present in almost all brands of Titan. It is easily accessible and relatively cheap, and its density less than the density of titanium, so the specific strength of the alloy in the amount of increases. It hardens the alloy without loss of ductility. With increasing aluminum content increases the heat resistance and the modulus of elasticity and reduced tendency to hydrogen embrittlement. Molybdenum increases corrosion and chemical resistance, heat resistance, suppresses the formation of α-phase during hardening. When a large enough quantity of β-stabilizers in the formation of α-phase is suppressed without α-stabilizers and neutral reinforcers.

On the surface of the wire, round, rod should not be dark spots, places reproterol. The color should be clean and bright, with no shades of tint. The waviness associated with annealing, is not considered a marriage.

Dignity

VT3−1 wire, round, rod differ corrosion and chemical resistance, high heat resistance, a low coefficient of thermal expansion, lightness and flexibility. Fatigue resistance depends significantly on the external environment. Vacuum titanium alloys have a higher endurance than in air. A great influence on the cyclic endurance of titanium semi-finished products having the condition and quality of the surface. Under the surface quality meant its roughness, macro — or micro-roughness, under the condition of the surface — structure, physico-mechanical properties of the surface layers, depending on the mode of mechanical treatment. The least influence on the endurance limit has a gentle end machining with the removal of a thin shaving to 0.1 mm with a subsequent manual polishing of the copper skin to 8−9 classes of roughness. The worst fatigue was observed after abrasive grinding and cutting accelerated.

Disadvantages

The high labour intensity of production, high cost are the main drawbacks. It is important to note that the strength properties of alpha+beta titanium alloys less when tested in tension, than when tested in compression.

Application

VT3−1 wire, rod, circle is used for the production of the most critical parts that can withstand the extreme conditions in shipbuilding, aircraft and rocket construction. In the chemical, petrochemical or oil and gas industry are crucial to corrosion resistance and acid resistance of the alloy, and in the food industry, agriculture, medicine and biological inertness.
