Abstract
In this paper, the variation of the Young’s modulus with plastic deformation during unloading in a tensile test with has been determined for a wide range of Dual-phase steels, covering from DP 1400 to DP 780. As a general rule, the higher strength steels have a lower variation (8%) and as the strength decreases, this diminution increases, arriving to 20%. However, in the softer steels, there are appreciable differences in young’s modulus variation although their mechanical properties are ver...
