The paper studies the influence of 0.5–1.8 wt.% Ni alloying on superplasticity, microstructural evolution, and dynamic grain growth effect in a temperature range 625–775 °C room mechanical properties two-phase Ti-Al-Mo-V alloys. Due to decrease β transus an enhancement alloy diffusivity, increase content significantly improved superplasticity. Ni-modified alloys exhibited 1.5–3-fold lower flow ...

Superplasticity refers to the ability of some materials pull out tensile elongations 400% or more when strain rate sensitivity is ~0.5. The first report true superplastic flow was published in 1934 experiments conducted England. However, this remarkable result attracted little interest among western scientific researchers and remained a laboratory curiosity for many years. Later, following exte...
