ASTM E646 Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials
We are confident that we have what you are looking for. Caution should be observed in the use of curve-smoothing techniques as they may affect the n -value.
ASTM E is for metallic sheet materials with thicknesses of at least 0. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are astj considered standard.
ASTM E646 – Tensile Strain-Hardening Exponents (n-Values) of Metallic Sheet Metals
E Clip On Axial Extensometer. A single power curve may not be a satisfactory fit to the entire stress-strain curve between yield and necking.
The method has successfully been and may be applied to other forms and thicknesses by agreement.
If such is the case, more than one value of the strain-hardening exponent may be obtained 2 by agreement using this test method. Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. Historical Version s – view previous versions of standard. Work Item s – proposed revisions of this ast.
ASTM E Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials
The strain-hardening exponent is also a measure of the increase in strength of a material due to plastic deformation. 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.
Link to Active This r646 will always route to the current Active version of the standard. Practically, it provides an empirical parameter for appraising asgm relative stretch formability of similar metallic systems.
By means of our tensile testing expertise and modular product design, we will help find the solution that is right for you. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Give our test engineers a call today astj help configuring the best test machine and accessories according to ASTM E 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. The value of the strain-hardening exponent, nhas no units and is independent of the units used in its determination.
