ABSTRACT

Powder Metallurgy is a fabrication tool that has been in practice since ancient times till now. The Iron Pillar in Delhi is the best example of powder metallurgy which was built in 1600 years ago. This process includes various processes among which compaction of metal powder performs a vital role. The powder density at the beginning of process and the synergy of powders and its particles and die/punch play a significant role in the final quality of the compact. Studying the impact of various shapes, punching schedules, and material interactions is an essential for achieving better results. Extensive experiments are required to establish the optimized parameters to get the desired results for a particular powder mixture. By reviewing various research papers. This research seeks to develop a pressure compaction die that compacts metal powder with minimum porosity and microcracks. By applying maximum pressure through a ANSYS Software, simulation, and Universal Testing machine the performance of the die has also been tested by analyzing the compaction behaviour of metal powder, the porosity produced during compaction, and its mechanical properties.
