Abstract Scope |
A thermodynamic model will be presented for predicting the embodied energy and carbon footprint of titanium alloys (e.g. Ti-6Al-4V) produced by a press-and-sinter powder metallurgy process. The final step of the modeled process is continuous belt sintering. However, the mass/energy balance and parasitic energy losses were modeled for the entire PM process from powder preparation to compaction and sintering, including the embodied energy of consumables. Theoretical values were produced via thermodynamic calculations, and these values were then adjusted for efficiency based on literature values of the various processes and equipment. Therefore, the energy efficiency and cost-effectiveness of the entire process on a commercial scale was evaluated. The current model focuses on a hydrogen sintering process for producing titanium alloys developed by the authors, but the model has been developed to be adaptable to various press-and-sinter processes and alloys. |
