Phase field calculation of interface mobility in a ternary alloy
چکیده انگلیسی

A novel approach based on the quantitative phase field model was proposed to calculate the interface mobility and applied to the α/β interface of a ternary Ti–6Al–4V alloy. Phase field simulations indicate that the higher interface mobility leads to the faster transformation rate, but only a unique value of interface mobility matches the diffusion equation under the diffusion-controlled condition. By comparing the transformation kinetics from phase field simulations with that from classical diffusion equation, the interface mobility at different temperatures can be obtained. The results show that the calculated interface mobility increases with increasing temperature and accords with Arrhenius equation very well.
