This study investigates the fabrication and characterization of coppergraphite (CuGr) composites with varying graphite content (10, 20, and 30 wt.%) for potential applications in electrical contacts, such as pantograph sliders for high-speed trains. The composites were prepared using mechanical...

This study investigates the influence of pressing schemes on the distribution of residual porosity in powder metallurgy products, focusing on onesided and two-sided cold pressing methods. Using analytical modeling, the distribution of porosity along the height of a bushing-shaped compact is...

This article analyzes modern technologies used in obtaining structural materials based on iron powder with high physical-mechanical and operational properties. It examines raw powder materials, practical and scientific results achieved in the field, and existing challenges in this area....

This study investigates the compaction of iron-based powders to produce high-density components with enhanced mechanical properties. A mathematical model analyzes stress distribution, porosity, and deformation under different pressing schemes, considering the influence of external friction. The...
