GB/T 5028-2008 金属材料.薄板和薄带.拉伸应变硬化指数(n值)的测定
简介：本标准规定了金属薄板和薄带拉伸应变硬化指数（n值）的测定方法。本方法仅适用于塑性变形范围内应力-应变曲线呈单调连续上升的部分（见7.4）。如果材料在加工硬化阶段的应力 -应变曲线呈锯齿状（如某些AlMg含金呈现出的Portevin-Le Chatelier 锯齿屈服效应），为使所给出的结果具有一定的重复性，应采用自动测量方法（对真实应力-真实塑性应变的对数进行线性回归，见 7.7）。

ASTM E646-2000 金属薄板材料拉伸应变硬化指数(N-值)的标准试验方法
简介：This test method is useful for estimating the strain at the onset of necking in a uniaxial tension test (1). Practically, it provides an empirical parameter for appraising the relative stretch formability of similar metallic systems. The strain-hardening exponent is also a measure of the increase in strength of a material due to plastic deformation. The strain-hardening exponent may be determined over the entire plastic stress-strain curve or any portion(s) of the stress-strain curve specified in a product specification. Note 38212;The strain interval 10x2013;20% is commonly utilized for determining the n-value of formable low carbon steel products. This test method is not intended to apply to any portion of the true-stress versus true-strain curve that exhibits discontinuous behavior; however, the method may be applied by curve-smoothing techniques as agreed upon. Note 48212;For example, those portions of the stress-strain curves for mild steel or aluminum alloys which exhibit yield-point elongation or Luuml;ders bands may be characterized as behaving discontinuously. Note 58212;Caution should be observed in the use of curve-smoothing techniques as they may affect the n-value. This test method is suitable for determining the tensile stress-strain response of metallic sheet materials in the plastic region prior to the onset of necking. The n-value may vary with the displacement rate or strain rate used, depending on the metal and test temperature.1.1 This test method covers the determination of a strain-hardening exponent by tension testing of metallic sheet materials for which plastic-flow behavior obeys the power curve given in the Introduction. 1.2 This test method is for metallic sheet materials with thicknesses of at least 0.005 in. (0.13 mm) but not greater than 0.25 in. (6.4 mm). 1.3 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents shown may be approximate. 1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ISO 10275-1993 金属材料 薄板和钢带 拉伸应变硬化指数的测定
简介：The principle of the test method specified is subjecting a test piece to uniaxial tensile strain at a prescribed constant rate within the region of uniform plastic strain. It is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic. The tensile strain hardening exponent is calculated either by considering a portion of the stress-strain curve in the plastic strain region, or by considering the whole of the uniform plastic strain region.

简介：Diese Internationale Norm legt ein Verfahren zur Bestimmung des Verfestigungsexponenten n im Zugversuch von Flacherzeugnissen (Band und Blech) aus metallischen Werkstoffen fest. Das Verfahren ist nur anwendbar fur den plastischen Bereich der Spannung/Dehnung-Kurve, in dem die Kurve kontinuierlich und monoton verlauft (siehe 7.4). Bei Werkstoffen mit gezackter Spannung/Dehnung-Kurve im Verfestigungsbereich (Werkstoffe mit Portevin-Le Chatelier Effekt, z. B. AlMg-Legierungen) sollte die automatisierte Bestimmung (lineare Regression der logarithmierten wahren Spannung uber die logarithmierte wahre plastische Dehnung, siehe 7.7) angewendet werden, um reproduzierbare Ergebnisse zu erhalten.
