Comparative Study of Pseudo-α and Pseudo-β Class Titanium Alloy Sheet Set of High-Tech Properties

  • Published:
Metallurgist Aims and scope

A forming operations for the pseudo-α titanium alloys OT4-1, OT4-1V, OT4V that are used traditionally in aviation and aerospace transport structures, and a new advanced high-strength metastable β-titanium alloy VT47. It is shown that metastable β-titanium alloy VT47 provides the possibility of implementing manufacturing technology for preparing components of complex configuration by cold sheet forming with a degree of deformation equal to that of reference alloys (OT4-1, OT4-1V, OT4V). Additional ageing of VT47 workpieces provides a significant increase in strength properties.
