Metallic materials - Sheet and strip - Determination of tensile strain hardening exponent (ISO 10275:2020)

This document specifies a method for determining the tensile strain hardening exponent n of flat products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic (see 8.4).
In the case of materials with a serrated stress-strain curve in the work hardening range (materials which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys), the automatic determination (linear regression of the logarithm true stress vs. the logarithm true plastic strain, see 8.7) is used to give reproducible results.

Metallische Werkstoffe - Blech und Band - Bestimmung des Verfestigungsexponenten im Zugversuch (ISO 10275:2020)

Dieses Dokument legt ein Verfahren zur Bestimmung des Verfestigungsexponenten n im Zugversuch von Flacherzeugnissen (Band und Blech) aus metallischen Werkstoffen fest.
Das Verfahren ist nur anwendbar für den plastischen Bereich der Spannung/Dehnung-Kurve, in dem die Kurve kontinuierlich und monoton verläuft (siehe 8.4).
Bei Werkstoffen mit gezackter Spannung/Dehnung-Kurve im Verfestigungsbereich (Werkstoffe mit Portevin Le-Chatelier-Effekt, z. B. AlMg-Legierungen) wird die automatisierte Bestimmung (lineare Regression der logarithmierten wahren Spannung über die logarithmierte wahre plastische Dehnung, siehe 8.7) angewendet, um reproduzierbare Ergebnisse zu erhalten.

Matériaux métalliques - Tôles et bandes - Détermination du coefficient d'écrouissage en traction (ISO 10275:2020)

Le présent document spécifie une méthode pour la détermination du coefficient d'écrouissage en traction, n, des produits plats (tôles et bandes) en matériaux métalliques.
La méthode n'est valable que pour la partie de la courbe contrainte-déformation dans le domaine plastique où la courbe est continue et monotone (voir 8.4).
Dans le cas de matériaux avec une courbe contrainte-déformation en dents de scie dans le domaine de consolidation (matériaux qui présentent l'effet Portevin-Le Chatelier, par exemple les alliages AlMg), on utilise la détermination automatique (régression linéaire du logarithme de la contrainte vraie en fonction du logarithme de la déformation plastique vraie, voir 8.7) pour obtenir des résultats reproductibles.
