Superplasticity and solid-phase bonding of nanostructured materials. Part II. The model of the solid-phase joint formation in titanium alloy under low-temperature superplasticity

Abstract: The manuscript presents a review of recent studies on the effect of superplasticity (SP) on solid-phase weldability of crystalline materials. A model of solid-phase joining for nanostructured titanium alloy VT6 under low temperature SP is considered. We justify the perspectives of application of nanostructured materials in the development of cuttingedge, recource-saving technologies for manufacturing hollow components for aviation and engine industries pressure welding.Keywords: low temperature superplasticity… Show more

“…It is shown that the quality hard phase joining of titanium alloy VT6 by pressure welding in conditions of low temperature plasticity depends on the deformation level [15]. At the same time, the necessary value of deformation level increases while the temperature decreases [16].…”

“…Дальнейшее увеличение степени деформации сопровождается резким ростом зерен до микрокристаллических размеров [8 -11], что отражается на механических свойствах сварных образцов. Влияние исходного размера зерен и эффекта структурной сверхпластичности (СП) являются определяющими в ускоренном формировании физического контакта [12,13]. Роль диффузии при этом также крайне важна, в частности на стадии объемного взаимодействия, но она практический не исследована для титановых сплавов при пониженных температурах, в том числе при проявлении низкотемпературной сверхпластичности (СП).…”
