The manuscript considers microstructure, mechanical and processing properties (formability and solid state weldability) of sheet titanium alloy VT6(Ti-6Al-4V) with improved superplastic properties production of JSC «VSMPO-AVISMA Corporation" for the process of superplastic forming at low temperatures and new experimental cheaper sheet titanium allo...
The manuscript considers the effect of diffusion bonding pressure, as well as holding at different temperatures, on the strength of the joints between titanium alloy and stainless steel, formed by diffusion bonding through ultrafine-grained interlayers of Ni and the Ni-2%Cr alloy. In samples with an interlayer of nickel after holding at 25 °C, the...
A computer simulation of the process of wedge-press welding (WPW) of dissimilar materials was carried out using the example of titanium alloy and stainless steel through a nickel layer. The initial model of the embedded part was a cylinder with a conical top. The model of a detail to which the introduction was carried out represented a conic blind...
The mechanical properties and the fracture of the joints between a PT3V titanium alloy and 12Cr18Ni10T stainless steel formed by diffusion welding through ultrafine-grained layers of nickel and a Cr2Ni98 alloy are studied. The highest strength of the joint (about 390 MPa) is achieved upon welding at T = 700°C, 20 min irrespective of the interlayer...
Investigations of technological properties of new titanium alloy sheet VST2k have been conducted. It is found that the titanium alloy has a good solid state weldability and formability under conditions of superplasticity at temperatures 750-900C. By the method of SPF/DB sheet of VST2k alloy in a low-temperature superplasticity at a temperature of...
Microstructure, nanohardness, and special features of fracture of three-phase titanium alloy and stainless steel joint through a nanostructural nickel foil are investigated. Uniformly distributed microcracks are observed in Ti2Ni and TiN3 layers joined at temperatures above T = 700°C, whereas no microcracks are observed in the TiNi layer. This sugg...
The effect of two stop-off coatings on the structure and hardness of the surface of the titanium alloy VT6 has been investigated. Data for nondestructive diagnostics of the surface layer have been obtained by the method of acoustic emission. Results of this study can be of use for quality control of hollow parts fabricated from titanium alloys.
Uniformity of deformation in bonding zone during pressure welding of titanium alloy to stainless steel with nickel interlayer was studied. It was shown that in the case of flat surfaces the stagnant zones in the center of the samples are formed and formation of bonds takes place non-uniformly: edges of the samples are seized, while in the center th...
