摘要：

In this study, for the first time, non-isothermal oxidation behavior of the AM Ti-6Al-4V alloy was investigated through TGA-DTA to predict and determine the oxidation mechanism. TGA results were evaluated by both model-free kinetic models and model-fitting methods. The model-fitting kinetic method was applied to predict and determine the reaction mechanism. The obtained results indicate that the reaction is controlled by D2 and D3 models at heating rates of 5 and 10 degrees C/min, respectively. F2 and F1 control the reaction mechanism at heating rates of 20 and 50 degrees C/min, respectively. The results of this study indicate that oxidation kinetics vary with reaction time, allowing us to predict which materials are most favorable to use under certain conditions with respect to oxidation applications.
