The responsible German body involved in its preparation was the Normenausschuss Materialprfung (DIN Standards Committee Materials Testing), Working Committee NA 062-01-42 AA Zug- und Duktilittsprfung fr Metalle. Users of this standard should take note of the following: This
7、standard describes the determination of the tensile strain hardening exponent at room temperature. The equations for calculating the true stress (Equation 3), the true plastic strain (Equation 4) and the true cross-section area (Equation 5) are based on the assumption that the parallel length of the
8、 test piece in the area under evaluation remains prismatic and that there is no formation of a neck or waist. Depending on the material/material condition, waisting along the parallel length of test pieces may occur long before a neck actually is formed. This effect is, in general, still more pronou
9、nced at elevated temperatures. For this reason it should be noted that the unrestricted application of the method described in this standard is not possible at elevated temperatures. Besides the following two points that, according to the standard, are required to be satisfied when considering the l
10、ower limit of the plastic (engineering) strain for the regression method: the final testing rate needs to have been reached (this being the rate after the yield/proof strength and yield strength elongation have been determined, i.e. the rate at which the tensile test is generally continued and at wh
11、ich Rmand Ag, for instance, are determined; the plastic (engineering) strain needs to be greater than the yield strength elongation; the following aspect should also be taken into account: the measuring data density needs to be constant, as is the case with the upper limit; the reason being that as
12、the data density is initially higher in the tensile test (i.e. in the elastic region and the region in which the yield strength is determined), the results would otherwise be weighted in favour of the determined range close to the lower limit. According to Table 1 (in analogy with the English refere
13、nce version), epdefines the plastic (engineering) strain at which the tensile strain hardening exponent is determined using the manual evaluation method given in Subclause 7.6. The explanation in parentheses (“single data point method”) is also expressed as the “manual method”. ISO 6892:1998 cited i
