The die-wall friction is one of the influential mechanical factors in the metal nano-powder
compaction process that can noticeably impress the densification behavior of nanoparticles …

In this study, the friction mechanism and its relation to the force chains during powder
compaction were analyzed by using the discrete element method. The results showed that …

The frictional behavior during powder compaction and ejection is studied using an
instrumented die with eight radial sensors. The average friction over the total powder pillar is …

It is known that the shape of a cutting insert blank, after pressing and sintering, can be
predicted with finite element (FE) simulations. It is also known that such simulations have the …

Spray-dried refractory carbide and metal powder mixtures, containing tungsten carbide, is
compacted and sintered during the production of conventional cutting tool inserts. Since …

Material parameter curves in an advanced material model describing compaction of spray
dried cemented carbide powder are determined successfully based on a general approach …

Density variations in pressed powder materials are of substantial importance and will affect
shrinkage and geometry after sintering. It is therefore important to accurately measure this …

According to the granulometric composition, the initial mixture had an average particle size
of 0.7601 microns. The pressing was carried out with preliminary vibration-mechanical …
