Project Overview
In this example, we intend to simulate the hot backward extrusion of Titanium alloy (Ti-6Al-4V) in the Abaqus software.
This model is composed of Titanium alloy, Die, and Punch. The Die and Punch are modeled as rigid bodies, while the Titanium alloy is modeled as a deformable body.
Hot backward extrusion model of Ti-6Al-4V Titanium alloy.
Temperature Conditions
The initial temperature of the Titanium alloy is 880 °C, while the initial temperature of the Die and Punch is 350 °C.
During the hot backward extrusion process, the temperature of the Titanium alloy changes due to the deformation of the workpiece. The initial temperature of the workpiece is 880 °C, and as a result of the backward extrusion process, its temperature increases and reaches approximately 921 °C. This temperature increase is associated with the deformation of the workpiece during the extrusion process.
Initial temperature of the workpiece is 880 °C.
Final temperature of the workpiece is 921 °C.
Axisymmetric Modeling
Since the Die, Punch, and Titanium alloy have a cylindrical shape, the Axis-Symmetric method is used to simulate the model.
The axisymmetric approach allows the cylindrical extrusion process to be modeled efficiently while maintaining the geometry and deformation characteristics of the problem.
Ultimate Deformation of Titanium Alloy
After the hot backward extrusion process, the ultimate deformation of the Titanium alloy can be observed in the Abaqus results.
The final configuration shows the deformation and material flow of the Ti-6Al-4V alloy during the extrusion process.

Reaction Force of Punch
Another important result obtained from the Abaqus simulation is the reaction force of the Punch.
The reaction force of the Punch is evaluated during the extrusion process and presented as a diagram to show the force response throughout the analysis.
