ASTM E is for metallic sheet materials with thicknesses of at least 0.
Practically, it provides an empirical parameter for appraising the relative stretch formability of similar metallic systems. The method has successfully been and may be applied to other forms and thicknesses by agreement.
ASTM E646 Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials
The value of the strain-hardening exponent, nhas no units and is independent of the units used in its determination. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
A single power curve may not be a satisfactory fit to the entire stress-strain curve between yield and necking. If such is the case, e6446 than one value of the strain-hardening exponent may be obtained 2 by agreement using this test method.
Have a question about conducting the test for this standard? Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0.
Work Item s – proposed revisions of this standard.
E Clip On Axial Extensometer. ASTM E covers the determination of a strainhardening exponent by tension testing of metallic sheet materials for which plastic-flow behavior obeys the power curve given in the Introduction. D646 strain-hardening exponent is also a measure of the increase in strength of a material due to plastic deformation.
Caution should be observed in the use of curve-smoothing techniques as they may affect the n -value.
