Resumo

The compaction pressure is a parameter that plays an important role not only on compaction process itself, but also in post-processing (sintering, post-sintering, etc.). The compacted powder is kept together mainly by adhesive forces, which magnitudes influence the properties of the material obtained via powder metallurgy (PM) route. Therefore, this paper presents a short review on the effect of compaction pressure on properties of materials obtained via PM. This includes the state of the art on this topic, displaying the research evolution of this area. The review starts with definitions and concepts about PM and compaction pressure. The following section presents the progress on research about the relationship between compaction pressure and material properties. The next section shows a discussion about possible tendencies and opportunities of research in this growing area. The final section of this paper corresponds to the conclusions drawn.
