Purpose: The paper reports characteristic of superplasticity phenomenon in titanium alloys and possibility of its applications. Design/methodology/approach: The main objective of the paper is to show features of superplastic forming of titanium alloys and current research trends aiming at widespread application of this technology. Findings: In the paper characteristic of selected superplastic titanium alloys was presented. The effect of microstructural parameters on superplasticity was considered too. Mechanical properties of superplastic deformed titanium alloys, determining criteria of their potential applications, were also addressed. Research limitations/implications: Application of superplastic forming (SPF) in industry is limited due to long time and high temperature of the forming process. In the paper directions of the studies were presented which can lead to increase in effectiveness of the process. Practical implications: SPF enables manufacturing of complex shape details in one-step technological operation. Together with diffusion bonding (DB) it offers particular advantages making possible to manufacture complicated multilayer structures. Originality/value: The paper summarizes achievements of the studies on the superplasticity of Ti alloys, emphasizes the role of microstructural parameters and methods of their modification leading to better results and economics of SPF.
