Definitions

  • materials and products such as sheet materials, and sheet semi-products, such materials and products comprising titanium alloys, the materials being suitable for product fabrication by methods including low temperature superplastic forming (SPF) at a temperature of 775 °C.
  • SPF low temperature superplastic forming
  • the materials and products can be used as cost-effective options to sheet products made of Ti-6Al-4V alloy.
  • superplastic forming is generally applicable to a process in which a material (alloy) is being superplastically formed under exceeded conventional limit of plastic strain (over 500%). SPF may be applied to certain materials exhibiting superplastic properties within the limited ranges of temperatures and strain rates. For example, titanium alloy sheets are normally able to undergo superplastic forming (deformation) within the temperature range of about 900 to 1010°C at the strain rate of about 3 ⁇ 10 -4 s -1 .
  • a decrease in the SPF forming temperature may result in a reduction of die cost, an increase of its life and may potentially lead to an introduction of less expensive steel dyes.
  • formation of an oxygen-rich layer (alpha case) and scale may be mitigated, thus improving product yield and reducing or eliminating the requirement of chemical etching.
  • the advantage of retaining the presence of finer grains after completion of SPF operations may result in lower deformation temperatures, which may lead to restrain in grain growth.
  • the second approach involves developing of new system of titanium alloy sheet materials exhibiting superplasticity at coarser material granularity because of:
  • Two-phase ( ⁇ + ⁇ )-titanium alloys are classified as alloys having molybdenum structural equivalents - [Mo]equiv. - equal to 2.5 up to 10%.
  • Such alloys are usually being alloyed with aluminum and ⁇ -stabilizers to retain the ⁇ -phase.
  • the amount of ⁇ -phase may vary from 5% to 50% in as-annealed alloys belonging to this group. Therefore, mechanical properties change over relatively wide range.
  • alloys had widespread use in both Russia and foreign countries, in particular, Ti-6Al-4V alloy due to successful addition of alloying elements.
  • the aluminum tends to increase the strength and heat resisting properties
  • the vanadium is among one of the few elements that increases not only strength properties, but also improves plasticity.
  • Alloys belonging to Ti-6Al-4V group are used to produce bars, tubes, sections, open- and close-dye forgings, plates, sheets, strips and foil. They are used for fabrication of welded and prefabricated structures in airborne vehicles, a number of aviation and rocketry structural components, as well as for fabrication of medical implants to be applied in traumatology, orthopedics and odontology.
  • Ti-6Al-4V alloy has been known to have a sub-microcrystalline structure produced by severe plastic deformation (SPD) with the use of all-round forging technique and exhibiting superplastic properties.
  • the alloy microstructure is defined by ⁇ - and ⁇ -phase grains and subgrains having an average size of 0.4 ⁇ m, high level of crystal lattice internal stresses and elastic distortions as evidenced by non-uniform diffraction contrast, and high density of dislocations on images of the structure obtained by electron microscopy.
  • S. Zherebtsov, G. Salishchev, R. Galeyev, K. Maekawa Mechanical properties of Ti-6Al-4V titanium alloy with submicrocrystalline structure produced by severe plastic deformation. // Materials Transactions. 2005; V. 46(9): 2020-2025 ).
  • To manufacture sheet semi-products from this alloy non-intensive and low-cost SPD operations with the use of all-round forging technique are required that significantly increase finished product value.
  • Sheet semi-products with the thickness of ⁇ 3 mm manufactured within the patent may not be suitable for industrial production due to the low stability of properties required for SPF.
  • the reason is that the use of strength equivalents as adjusters of the alloy chemical composition does not allow the adjustment required and appropriate relations between alloying elements in the alloy and structural properties of the alloy required for performance of SPF operations with sheet semi-products.
  • the presence of Si and Zr in the alloy may form silicides on the grain surfaces thereby hindering intergranular sliding and resulting in process instability.
  • ( ⁇ + ⁇ )-titanium alloy sheet material with the ability to lower temperature superplastic forming with the grain size exceeding 2 ⁇ m.
  • the sheet material exhibits stable properties and, in examples, is a cost-effective option to sheet semi-products made of Ti-6Al-4V alloy with finer grains.
  • Sheet material for low temperature superplastic forming has the structure consisting of grains with the size below 8 ⁇ m.
  • Sheet material for low temperature superplastic forming may exhibit superplastic properties at a temperature of 775 ⁇ 10°C.
  • Sheet material for low temperature superplastic forming at a temperature of 775 ⁇ 10°C exhibits ⁇ / ⁇ phase ratio from 0.9 to 1.1.
  • the provided sheet material in examples herein, exhibits a set of high processing and structural properties. This is achieved by efficient selection of alloying elements and their ratio in the material alloy.
  • Aluminum which is used in substantially all commercial alloys, is the most efficient strengthener and improves the strength and heat resisting properties of titanium. Oxygen increases the temperature of titanium allotropic transformation. The presence of oxygen within the range of between 0.16% to 0.25% increases the strength of the alloy and does not have a significant negative impact on plasticity.
  • Group of ⁇ - stabilizers (V, Mo, Cr, Fe, Ni) are widely used in commercial alloys.
  • Vanadium in the amount of 4.5% to 5.5%, iron in the amount of 0.8% to 1.5% and chromium in the amount of 0.1% to 0.5% increase the alloy strength and have relatively little or no negative impact on plasticity.
  • molybdenum ranging between 0.1% to 1.0% ensures its almost complete to complete dissolution in ⁇ -phase, thus the required strength properties may be achieved, in examples, with little to no negative impact on plastic properties.
  • the provided alloy contains iron in the amount of 0.8% to 1.5, or 1.0% to 1.5% and nickel in the amount of 0.1% to 0.5%. These elements are the most diffusible ⁇ - stabilizers that have a positive impact on intergranular sliding at SPF.
  • the first to be distinguished is the size of grain which is not to exceed 8 ⁇ m (experimental data) for the provided material.
  • molybdenum structural equivalent [Mo]equiv. shall be greater than 5 and the value of aluminum structural equivalent [Al]equiv. shall not exceed 8. Besides that aluminum equivalent value above that stated above results in BTT increase and consequently to increase of SPF temperature.
  • Optimum temperature to effect superplastic properties of the provided material equals 775 ⁇ 10°C.
  • the amount of alloying elements diffusible between ⁇ - and ⁇ - phases shall not be less than 0.5%. This is due to the fact that the activation energy of grain-boundary diffusion is less than the activation energy of volume diffusion, and the diffusion transport of atoms is being carried out at grain boundaries. Those areas of grain boundaries being influenced by normal tension stress and exhibit increased concentration of vacancies. Those areas being influenced by compressive stress exhibit less concentration of vacancies: resulting in a difference in concentrations causing direct diffusion of vacancies. Since migration of vacancies involves interchange with atoms, the latter will move in opposite direction thus causing intensification of intergranular sliding.
  • sheet semi-products having thickness of 2 mm were used.
  • six experimental alloys of various chemical compositions given in Table 1 were melted.
  • Sheet materials of 2 mm thick were manufactured against known method of manufacture and intended for superplastic forming. Before being tested for superplastic properties, the materials were subject to annealing at a temperature of 720 °C during 30 minutes and then subjected to subsequent air cooling. After the processing steps were completed, samples were taken from the sheets in longitudinal and transverse direction for tensile strength testing at room and elevated temperatures, and then the samples were subjected to typical testing at room temperature to determine strength, elastic and plastic properties. Table 1. Chemical Composition of Sheet Materials under Investigation Heat No.
  • Material 1 in initial condition is less uniform compared with other experimental alloys. Besides equiaxed grains, Material 1 demonstrates areas consisting of sufficiently bulk elongated grains. It also can be noted that morphology of ⁇ -phase varies in some way from alloy to alloy. Alloy 2 has minimum amount of alloying elements and ⁇ -phase is predominantly located as individual groups between ⁇ -phase particles; but beginning from Alloy 5 ⁇ -phase has definite coherency and besides grain texture it is shaped as relatively thin layers between ⁇ -phase grains. With [Mo]equiv. increase, these layers tend to thickening.
  • Table 4 includes calculation data related to the amount of alloying elements diffusible during SPF process.
  • Material 1 ( Figure 3 ) with the minimum content of alloying elements has the most unstable SPF process at a temperature of 775 °C that is described by typical waviness of stress-strain curves caused by formation of floating neck.
  • Such material behavior at SPF is attributed to relatively bulk initial grain (over 2.5 ⁇ m ) which has high growth rate at SPF (up to 5 ⁇ m ), at that ⁇ / ⁇ phase ratio (2/1) is not efficient and leads to activation of intragranular sliding which is less preferable for SPF instead of efficient intergranular slipping.
  • Material 2 ( Figure 3 ) has more additions of ⁇ -stabilizers, thus instability of SPF process in form of stress-strain curve waviness decreased compared with Alloy 1 due to increase in ⁇ -phase volume fraction in the structure. At that, no significant hardening was noted in the case of strain degree ranging from 0.6 to 0.8, due to the evolution of dynamic recrystallization within the areas of incompletely processed structure (presence of elongated grains) and this is not typical for all other alloys subjected to investigation.
  • Material 4 contains maximum amount of ⁇ -stabilizers and is additionally alloyed with 0.3% of nickel; it exhibited more stable superplastic behavior at a temperature of 775°C in both transverse and longitudinal directions, minimum stress at the beginning of the flow, absence of prominent curve waviness and monotonic hardening with the increase of strain degree. This is attributed to almost efficient ⁇ / ⁇ phase ratio (1/1) at deformation temperature as well as to maximum content of diffusible ⁇ -stabilizers (nickel, iron) compared with all the alloys under investigation, thus facilitating mass transport processes at intergranular slipping (total difference in change of alloying elements content between ⁇ - and ⁇ - phases during SPF process exceeds 1.9% wt.).
