Die Temperaturabhängigkeit der Verfestigungskenngrößen von Magnesiumeinkristallen

Abstract: Magnesiumeinkristalle wurden im dynamischen Zugversuch im Temperaturbereich von 77° K bis 453 °K verformt. Ähnlich wie bei Zink und Kadmium wird auch bei Magnesium eine Drei‐Bereiche‐Verfestigungskurve beobachtet. Die kritische Schubspannung nimmt bei tiefen Temperaturen mit wachsender Temperatur linear ab. Oberhalb von etwa 300 °K scheint sich ein weniger temperaturabhängiger Ast des τ0—T‐Diagramms abzuzeichnen. Der Temperaturverlauf der Verfestigungskoeffizienten in den Bereichen A und B der Verfestigungskur… Show more

“…The temperature and concentration dependence of the CRSS measured in the present work is very similar to that observed for Mg-Zn [ll]; Mg-In, Mg-A1 [12]; Mg-Li [29]; and Cd-Mg [15]; Cd-Zn [17,18,21 al. [30] contained a higher amount of impurities than those investigated by Sheely and Nash [31]. The values of K O are in good agreement.…”

“…Deruyttere and Greenough [19] reported for the first time that there could be a maximum of work hardening in Zn above 77 K , which was then found by Seeger and Trauble [9]. BoEek et al [20] considered this behaviour to be a specific effect of Zn. Rut as we could find out in this work, also Cd shows a maximum of work hardening.…”

“…There are some dierences in work hardening between fcc and hcp metals. The work hardening coecients θ A and θ B are temperature dependent [1,2]. In hcp metals, there are many types of slip systems with dierent Burgers vectors.…”
