Der Einfluß plastischer Verformung auf den Spaltbruch von Stahl

Abstract: Zugversuche an ungekerbten Kleinproben zwischen 10 und 200 K. Einfluß der Korngröße und der Vorverformung auf das Fließ‐ und Bruchverhalten. Approximation der Temperaturfunktion der Fließgrenze durch quadratisches Polynom. Hall‐Petch‐Analyse. Einfluß der Versuchsparameter auf die Konstanten der Hall‐Petch‐Gleichung. Aktivierungsanalyse. Temperaturabhängigkeit der Bruchspannung im Bereich des Spaltbruches, minimale und maximale Spaltbruchfestigkeit, Grenzwert der Spaltbruchfestigkeit. Einfluß der Versuchsparame… Show more

“…Fracture is predicted when the distribution of the maximum tensile stress component reaches a critical state. Ritchie et al [5] define this state as the situation when the maximum tensile stress component exceeds a critical value of across some characteristic length x, (about two grain diameters), Aurich and Wobst [6] predict cleavage when the peak value of the tensile stress component reaches a critical value (cf. Fig.…”
