ASTM E646 – Tensile Strain-Hardening Exponents (n-Values) of Metallic Sheet Metals
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.
A single power curve may not be ee646 satisfactory fit to the entire stress-strain curve between yield and necking. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The value of the strain-hardening exponent, nhas no units and is independent of the units used in its determination. E Clip On Axial Extensometer.
ASTM E Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials
We are confident that we have what you are looking for. It is the responsibility of the user of this standard to establish appropriate safety and health asym and determine the applicability of regulatory limitations prior to use. Practically, it provides an empirical parameter for appraising the relative stretch formability of similar metallic systems. ASTM E covers the determination of a strainhardening exponent by tension testing of metallic sheet materials for which d646 behavior obeys the power curve given in the Introduction.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
If such is the case, more than one value of the strain-hardening exponent may be obtained 2 by agreement using this test method. Give our test engineers a call today for help configuring the best test machine and accessories according to ASTM E Work Item s – proposed revisions of this standard.
Link to Active This link will always route to the current Active version of the standard. The 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. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
The method has successfully been and may be applied to other forms and thicknesses by agreement. By means of our tensile testing expertise and modular product design, we will help find the solution that is right for you. Have a question about conducting the test for this standard?
Force range of 5 kN to kN 1, lbf atsmlbf 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. ASTM E is for metallic sheet materials with thicknesses of at least 0.
