Influence of Cold Rolling Temperature Rise on the Young‘s Modulus of Commercial Fe-3%Si Steel

Abstract

Dynamic mechanical analysis was performed on the sheets of commercial grain-oriented steel Fe-3%Si in annealed and cold-rolled conditions. The Young`s modulus was measured according to the 3-point bending scheme in the temperature range of 20...550 ∘C. The difference between the values of the elastic properties in the rolling direction and transverse directions were explained with the peculiarities of the structural and textural states. Two extreme points in the Young`s modulus temperature dependence are explained with the oxidation process, which occurs during heating of the samples. The obtained data can be employed to refine the simulation of the stress-strain state in cold rolling of commercial Fe-3%Si by the finite element method.
