Abstract Scope |
Metastable beta titanium alloys are perspective candidates for the use in the aircraft industry and medicine due to their excellent strength, relatively low modulus of elasticity and enhanced biocompatibility.
A Ti15Mo, in a beta solution treated condition was subjected to severe plastic deformation (SPD) by high pressure torsion (HPT).
In order to optimize the parameters of the thermomechanical treatment of the alloy and to achieve a material with required mechanical properties, the phase transformations were examined in-situ by electrical resistivity and synchrotron X-ray diffraction and complemented by post mortem detail investigation of the microstructure and lattice defects in characteristic conditions by scanning and transmission electron microscopy and X-ray diffraction.
Lattice defects introduced by SPD significantly influence both the phase transformations and the morphology of the α-phase which results in enhancement of mechanical properties of the severely deformed material. |
