Modelling the high temperature oxidation of titanium alloys: Development of a new numerical tool PyTiOx

Abstract : The PyTiüx numerical tool was designed to mode! the high-temperature oxidation of titanium alloys by solving diffusion equations in a 1D finite size metal/oxide system with a moving metalloxide interface. Input parameters were selected to investigate Ti6242s alloy oxidation. PyTiüx overcomes certain limitations compared with analytical models, which can study different quantitative effects on both oxide scaling kinetics and oxygen diffusion in the alloy, such as nominal O concentration, thin samples and non-isotherrnal conditions. It also gives life span estimates. Calculations with non-isotherrnal conditions revealed the possible existence of a transient, oxide scale reduction regime after a drop in temperature.
