Effects of mold parameters on microscopic properties of cross wedge rolling (CWR) GH4169 alloy shaft parts

Shaft grain size and uniformity play an important role in improving its mechanical properties. Using DEFORM-3D finite element software, the effects of broadening angle and forming angle on the micro performance of the GH4169 alloy shaft parts were studied systematically.

Description
Summary:Shaft grain size and uniformity play an important role in improving its mechanical properties. Using DEFORM-3D finite element software, the effects of broadening angle and forming angle on the micro performance of the GH4169 alloy shaft parts were studied systematically. The results show that grain refinement is mainly completed in the stretching section. As the broadening angle increases, the grain size expands constantly, and the fluctuation value decreases and then increases, while as the forming angle increases, the grain size and the fluctuation value decrease and then increase. The accuracy of the finite element model was verified through cross wedge rolling experiments.
