Introduction to TA7 / Ti-5Al-2.5Sn titanium alloy
TA7 titanium alloy is a medium-strength α-type single-phase titanium alloy containing 5% α stable element aluminum and 2.5% neutral element tin. The alloy cannot be strengthened by heat treatment.
|Main ingredient ％||Impurity content ％,≤|
Density 4.42g / cubic centimeter, room temperature elastic modulus 113GPa, Poisson's ratio 0.33, hardness 277 ~ 286HB, melting point 172 Silicon titanium alloy wear-resistant floor 5 ℃, thermal conductivity λ = 15.24W / (mK), tensile strength σb = 539MPa, elongation δ = 25%, section shrinkage ψ = 25%, elastic modulus E = 1.078 × 105MPa
It is characterized by good thermal strength and good welding performance. Its process plasticity is low, and the sheet forming should be carried out in a heated state.
Titanium alloy classification
Titanium is an allotrope with a melting point of 1668 ° C. When it is lower than 882 ° C, it has a close-packed hexagonal lattice structure called alpha titanium; above 882 ° C it has a body-centered cubic lattice structure called beta titanium. Using the different characteristics of the above two structures of titanium, appropriate alloying elements are added to gradually change the phase transition temperature and phase content to obtain titanium alloys with different structures. At room temperature, titanium alloys have three matrix structures, and titanium alloys are divided into the following three categories: α alloys, (α + β) alloys, and β alloys. China is represented by TA, TC and TB respectively.
alpha titanium alloy
It is a single-phase alloy composed of α-phase solid solution. Whether it is at ordinary temperature or at a higher actual application temperature, it is α-phase, with stable structure, higher wear resistance than pure titanium, and strong oxidation resistance. At a temperature of 500 ℃ ~ 600 ℃, it still maintains its strength and creep resistance, but can not be strengthened by heat treatment, the strength at room temperature is not high.
Beta titanium alloy
It is a single-phase alloy composed of β-phase solid solution. It has high strength without heat treatment. The alloy is further strengthened after quenching and aging. The room temperature strength can reach 1372 to 1666 MPa; but the thermal stability is poor and it is not suitable for use at high temperatures. .
α + β titanium alloy
It is a two-phase alloy with good comprehensive properties, good organizational stability, good toughness, plasticity and high-temperature deformation properties, good hot-press processing, quenching and aging to strengthen the alloy. The strength after heat treatment is about 50% to 100% higher than that of the annealed state; the high temperature strength is high, it can work for a long time at a temperature of 400 ℃ to 500 ℃, and its thermal stability is inferior to the alpha titanium alloy.
Among the three titanium alloys, the most commonly used are α titanium alloy and α + β titanium alloy; α titanium alloy has the best machinability, followed by α + β titanium alloy, and β titanium alloy is the worst. The code name for α titanium alloy is TA, the code name for β titanium alloy is TB, and the code name for α + β titanium alloy is TC.
Production Process of titanium wire:
Titanium sponge→compacting electrodes→melting→forging→bar billets→hot rolling→cold draw→titanium wires
Surface quality: high precision, good finish, no oxidation color, no cracks, peeling, thorns, marks and inclusions. Minor
local scratches, abrasions, spots and pits that do not exceed the allowable deviation of the wire diameter are allowed.
