标准范围
This International Standard specifies a method for determining the tensile strain hardening exponent n of flatproducts (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 iscontinuous and monotonic (see 7.4).In the case of materials with a serrated stress-strain curve in the work hardening range (materials which showthe Portevin-Le Chatelier effect, e.g. AlMg-alloys) the automatic determination (linear regression of thelogarithm true stress vs. the logarithm true plastic strain, see 7.7) should be used to give reproducible results.
