Influence of forging velocity on temperature and phases of forged Ti-6Al-4V turbine blade
This study is prompted by the reality that the forging velocity significantly impacts the temperature and phases of titanium forged parts, further directly affecting the ultimate mechanical properties. In present work, a 3D FE model combined with phase transition equations is established to predict...
