Computational Modelling of Microstructural Deformation in Metastable β Titanium Alloys
Abstract
Metal forming is a manufacturing process in which a solid body is converted from an initial shape to a new one through mechanical deformation. Forming processes generally involve significant plastic deformation under complex multi-axial loading conditions. It is well known that metals can plastically deform via number of mechanisms: dislocation slip, twinning, the formation of stress/strain-induced martensite, or a combination of these. The interplay between the different deformation mechanisms significantly affects the mechanical behaviour of the metal.<br/>Martensitic transformation can be regarded as a mode of deformation; one which causes a change in the crystalline structure. Martensite transformation is usually triggered by heat treatment when the parent phase passes through the transformation temperature (MS) and the driving force equals a critical value. The application of an externally applied stress can also trigger transformation, this is termed stress/strain-induced martensite (SIM). This type of martensitic transformation results in a more ordered microstructure. A microstructure generated by favouring the formation of martensite aligned with the applied loading. The exact deformation mechanisms for SIM; influence of different alloying elements; microstructural evolution; and the interaction between SIM, elastic/plastic deformation, and failure of the material is not fully understood and is still an active area of research [1]–[4].<br/>In this study, a new CP-FEM formulation including SIM transformation along with conventional slip based plastic deformation is presented. The model is intended to investigate the interaction of SIM, slip-based plasticity, damage nucleation and growth in metastable 𝛽 titanium alloys. Providing insights into the influence SIM has on the bulk material response and microstructural evolution of metastable 𝛽 titanium alloys during metal forming processes.
