work hardening/ powder compactionIn this paper, three basic hypotheses are proposed, regarding the effects of porosity and work hardening on powder compaction for building a new pressure-density relation. After a short validation on some hard powders, complementary hypotheses are used for generalising ...
Compaction is a widely used method to form semi-finished or near-net-shape components from a powder. The quality of compaction (density gradients, micro-cracks) has a great influence on distortion of the product shape after sintering step as well as on the properties (defect-free components) ...
Armed with industry-leading technology and high accuracy machinery, our machines are able to form complex moulded parts which are uniform in density. Our powder compaction equipment is capable of compacting various powder materials which are pushed into a cavity whilst the compound is formed in the ...

Key problems of the main processes will be discussed, such as mass flow in the powder bed during compaction, which is required to achieve homogeneous density distribution in a part, or the role of powder lubrication.doi:10.1179/pom.1982.25.2.119None...
Key problems of the main processes will be discussed, such as mass flow in the powder bed during compaction, which is required to achieve homogeneous density distribution in a part, or the role of powder lubrication. Applications of powder compaction are described using examples from such areas ...
During compaction, the porosity of the aluminum powder decreases, while the density and strength of the component increases. Based on the geometry and loading used in this scenario, we can expect that the changes to the porosity will be nonuniform. ...
The material properties and yield surface function must consider this phenomenon into account since it may affect the redistribution of density and stresses. 1.7.1 The mathematical model As the forming process in powder compaction problems is a large deformation process, an elasto plastic analysis ...
