General characteristics

Wire, rod, circle are the most popular types of titanium semi-finished products. Alloy series include pseudo α-alloys of low heat resistance, but high plasticity. Their high-temperature properties depend strongly on the cooling rate. Cooling with an intermediate rate between the cooling water and oven gives the product the lowest level of creep.

Alloy t° the end of recrystallization t° of the beginning of recrystallization Bars, forgings. t° annealing.
OT4−0 800° 680° 690 — 740°
-4 860° 760° 740 — 760°
OT4−1 840° 720° 740 — 790°

In order to reduce residual stresses using partial annealing at a temperature less than the recrystallization temperature, annealing time is 0.5 — 2 hours with subsequent air cooling.

Deformable semi-finished products have a more or less pronounced anisotropy of properties. The coefficient of hardening of the alloy takes into account the effect of alloying, strengthening the relationship between the units. This ratio increases from 1.18 from pure titanium to 1.32 from complex brands with a high number of components. For the alloy OT4−0 this ratio is equal to 1.23. Semi-finished products series, easily welded all types of welding.

Disadvantages

The relatively low heat resistance and durability, the propensity for hydrogen embrittlement, in comparison with other brands of Titan. Production technology refers to the expensive and time consuming due to the relatively high resistance to cold deformation. A hot titanium readily interact with the gases of the atmosphere, but it also conducts heat poorly, creating large temperature gradients during processing. Therefore, the value of the finished product a much higher price of the feedstock.

Use

Structural efficiency, erosion, corrosion resistance, ballistic resistance and other advantages of semi-products FROM series make feasible their use in engineering, where they manufactured parts connecting rods, valves, crank and Cam shafts, transmission components, bolts, springs, valves, clutch parts. For example, the manufacture of connecting rods from titanium alloy enables 30% to reduce the load on the connecting rod bearings, greatly increasing their durability and reliability.
