2D Finite Element Model and Microstructural Changes During Cutting of Ti6A14V in Dry Condition

摘要

The mam objective of this study is to develop a FE model of the orthogonal cutting process executed on Titanium alloy (Ti6A14V) under dry condition. In detail, the Abaqus/Explicit 2D formulation has been used to simulate the process and the results provided (temperature and strain rate) where employed to calculate the microstructural and hardness changes on surface and sub-surface. The quantitative analysis in terms of the grain refinement and hardness variation during the cutting process has been provided taking into account the Zener-Hollomon and Hall-Petch equations. The obtained results were compared with the experimental outcomes in order to understand the reliable rate of the model.
