ChemInform Abstract: EFFECT OF THE MICROSTRUCTURE ON THE FATIGUE PROPERTIES OF ALMGSI1 ALLOYS

Abstract

Nach Untersuchungen an gekerbten Proben einer reinen und zweier technischer AlMgSi1‐Legierungen mit unterschiedlichem Gefügezustand zeigen, daß die beiden technischen Legierungen mit feinem (TF) und grobem Gefüge (TG) gleiche Lebensdauer bei stark unterschiedlicher Bildungsdauer von Rissen aufweisen.

Plane strain fracture toughness of scandium doped Al–6Mg alloy

“…Again solid solution hardening effect due to magnesium remains unaffected by the addition of scandium in Al-Mg alloy [16,20]. Although trace additions significantly influence the fracture toughness of age-hardenable aluminium alloys [21], the plane strain fracture toughness behaviour of Al-6Mg with trace scandium additions is not well documented in literatures. Hence the present investigation is aimed at studying the influence of inherent dispersoids and other microstructural features on the plane strain fracture toughness of Al-6Mg alloy trace added with scandium.…”
