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 …

Finite element (FE) simulations are frequently used nowadays in order to analyse powder
compaction and sintering, for example, when determining the shape of a cutting blank insert …

This study focuses on an inverse modelling approach, using FEM to simulate the sintering of
WC-Co powder using a continuum model. From a previously developed constitutive model …

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 …

The rate-dependence of hardmetal powder pressing in cutting insert production is
investigated experimentally and numerically. In the latter case, the finite element method is …

The correlation between granule strength and green strength of hard metal powders is
examined. The approach is based on experiments and numerics. In the latter case, a Design …

The relation between pressing energy and green strength is examined experimentally and
numerically using a commercially available design of experiment (DOE) software, at …

During unloading, pressed hard metal powder compacts expand (spring back), leading to
unwarranted tensile stresses and, subsequently, crack initiation in the green body. Here, the …

The densification of cemented carbides during sintering was studied using an existing
constitutive model based on powder particle size and material composition. In the present …
