Solute atom clustering during ageing an aluminium–magnesium–silicon solid solution under stress

摘要: A permanent increase of stress, Δσ, is found on the stress-strain curve after straining quenched AlMgSi alloy at 25 °C. Ageing it under stress for a time °C (or 52) and again °C, Δσ measured as function ageing time. It concluded that solute atom clustering to dislocations responsible „time dependent diffusion coefficient” via decay in vacancies, determines rate process change. Ein permanenter Anstieg der Spannung auf SpannungsDehnungskurve wird nach Belastung getemperter AlMgSi-Legierungen bei gefunden. Nach Alterung unter fur eine gewisse Zeit (oder und weiterer Deformation als Funktion Alterungszeit gemessen. Es geschlossen, das „zeitabhangige Diffusionskoeffizient” gelosten Atome die Prozesgeschwindigkeit Δσ-Anderung uber Abklingen eingetemperten Leerstellen bestimmt.
