Electromagnetic Powder Compaction: An Experimental Study of Its Effects on Titanium Powder

The compaction of metallic powders plays a crucial role in powder metallurgy and enabling the fabrication of high-performance components with desirable mechanical properties. This study focuses on assessing the compaction characteristics of titanium (Ti) powder utilizing the electromagnetic powder compaction technique. The electromagnetic powder compaction technique offers several advantages, such as reliable control over the compaction process, improved density uniformity, and reduced compaction time. This technique employs a pulsed magnetic field to consolidate metallic powders into solid compacts, ensuring optimal densification and minimizing defects. To investigate the compaction characteristics of Ti powder, a series of experiments were conducted. Firstly, Ti powder with specific particle size distribution and morphology was selected. Subsequently, the Ti powder was subjected to electromagnetic compaction under varying discharge energy and driving material. The compaction behavior of Ti powder was evaluated through various characterization techniques. The density, porosity, and dimensional stability of the resulting compacts were measured to assess the effectiveness of the electromagnetic compaction technique. Additionally, the microstructural analysis and hardness test were performed to evaluate the quality and mechanical properties of the compacts. The experimental results revealed the influence of different discharge energy on the compaction behavior of Ti powder. It was observed that variations in discharge energy significantly affected the density and mechanical properties of the compacts. Furthermore, the microstructural analysis provided insights into the grain morphology, grain boundaries, and potential defects within the compacts.
