Isothermal Hot Deformation Behaviour of Metastable Β Titanium Alloy Ti-10V-2Fe-3Al
Knott, J. F. (John Frederick)
Elevated temperature true stress-true strain curves have been determined for the isothermal deformation of the metastable β titanium alloy Ti-10V-2Fe-3Al in both the β and (α + β) phase fields using hot compression testing. The flow stress behaviour of the alloy, in two initial microstructural conditions, has been correlated with the microstructural changes taking place during hot deformation. The shape of the isothermal hot deformation stress-strain curve is strongly dependent upon the starting microstructure of the material. The operative restoration mechanism during deformation in the β field isdynamic recovery since β subgrains are readily observed in the as β forged condition. Dynamic recovery of the β phase is also considered to be the dominant restoration mechanism for both microstructural conditions during deformation at temperatures high in the (α + β) field.
