Numerical and experimental investigations of aluminium powder compaction and sintering

Abstract: Die Bildung von Dichtegradienten in Grünkörpern während des Pulverpressvorgangs und der daraus resultierende Sinterverzug stellt nach wie vor ein aktuelles Problem der Sintermetallindustrie dar. Demzufolge ist die Auslegung und Optimierung pulvertechnologischer Fertigungsverfahren zur Vermeidung derartiger Bauteilfehler des Presskörpers von entscheidender Bedeutung. Sie basiert bisher jedoch zu einem großen Teil auf Erfahrungswissen. Die numerische Simulation auf Basis der Finite-Element-Methode (FEM) bietet h… Show more

“…Thus, the green density impacts the final density of the component after sintering and therefore the mechanical properties, such as tensile strength, elongation at break and fatigue strength [4]. The green density is in turn governed by the compaction process and depends on material-and process-specific variables [5]. In this regard, important material-specific parameters are grain geometry, grain size and the powder material used [1].…”
