Study of Copper Alloy Formability at High Temperatures Using the Environmentally Friendly Formability Test (EFForT)
摘要
Hot forging is an industrial process that requires careful control of various forming parameters. Optimizing manufacturing processes in industrial settings requires a thorough understanding of the formability of materials such as CuZn40Pb2 brass at varying temperatures and forging speeds. The effectiveness, price, and quality of forged products are all directly impacted by these factors. By examining these variables, the study offers insightful information that can be used to choose the best processing conditions in order to achieve the required mechanical properties and reduce defects. Experimental tests are carried out using the EFForT test at temperatures ranging from 650 ℃ to 850 ℃ and forging velocities from 10 mm/s to 29 mm/s. The results show that temperature has a significant impact on the material flow process, and that increasing forging temperature and velocity can reduce the effort and energy required during the forging process. The study shows that raising the forging temperature to 680 ℃-820 ℃ cuts forging effort by 25%, and increasing the velocity to 29 m/s reduces energy consumption by 35%. These results highlight how higher temperatures and velocities improve forging efficiency, supported by detailed data from controlled experiments.
