Determination of the Neck Size between Powders during Sintering Process Using Finite Element Methods

Abstract

Today, sintering considers one of the significant processes that can be used in powder technology to produce a new solid product from powders using thermal energy. Many parameters can be successfully controlled by this process such as temperature, Particle size, process time, structure geometry, powder density, and powder composition. Study and analysis of the behavior of powder during the sintering process was carried out using finite element methods. The simulation provides two styles of discrete method and Qusi-static method. This research contributes to two types of processes in order to simulate the copper powder during the sintering process and to determine the variation by using contact and shrinkage ratios of powder behaviors. Finally, a comparison between the two styles of discrete element method explains how the selected parameters were impacted on the sintering process.

“…The validation of published investigations is mostly based on the comparison to analytical findings, such as equation (2). 17 Moreover, these methods have rarely been applied to real microstructures yet.…”
