Isothermal Hot Deformation Behaviour of (α + Β) Titanium Alloy Ti-4AI-4Mo-2Sn-0-5Si (IMI 550)
Knott, J. F. (John Frederick)
Elevated temperature true stress-true strain curves have been determined for the isothermal deformation of the (α + β) titanium alloy Ti-4Al-4Mo-2Sn-0.5Si (IMI 550) in both the β and (α + β) phase fields using hot compression testing. The flow stress behaviour of the alloy has been correlated with the microstructural changes taking place during hot deformation. It has been observed that the shape of the hot deformation stress-strain curve is strongly dependent upon the starting microstructure of the material. Dynamic recovery of the β phase is considered to be the dominant restoration mechanism for the temperature ranges studied.
