The LSPSF is particularly suitable for the ing of complex-shaped workpieces from difficult-to- materials such as titanium alloys. In this study, we will investigate the LSPSF coupled with gravity ing, which combines the gravitational force and the viscous flow of the metal to achieve ing. The objective of this study is to explore the effects of process parameters such as ing pressure, deation temperature, and gravity field intensity on the ability of titanium alloy using the LSPSF . ology: 1. Material: Commercially pure titanium (CP Ti) will be used in the study. 2. Experimental setup: The ing equipment will consist of a cylindrical die and a punch-mounted on a hydraulic press. The die will be heated by an induction heating system, and a gravity field will be created by natural gravity. 3. Experiment design: The ing process will follow the LSPSF by imposing a large shear strain to the material through the combination of punch motion and the natural gravity force. A full factorial design of experiments will be used to investigate the influence of process parameters such as ing pressure, deation temperature, and gravity field intensity on the ability of the titanium alloy. 4. uation of results: The ed samples will be uated using X-ray diffraction analysis, scanning electron microscopy, and mechanical testing to determine the microstructure, surface quality, and mechanical properties. Expected Outcome: The LSPSF coupled with gravity ing may provide a new and efficient way of processing titanium alloys. By optimizing the process parameters, we expect to achieve high-quality components with reduced ing pressure and improved material utilization. The experimental results may also provide insights into the deation mechanisms of titanium alloys during LSPSF ing. Conclusion: The proposed study aims to investigate the LSPSF coupled with gravity ing for titanium alloy ing. This study will provide a systematic uation of the effects of process parameters on the ability of titanium alloy components, laying the foundation for the optimization of the LSPSF ing process. The outcomes of this research may lead to the development of new and efficient processing techniques for titanium alloys.
