Abstract
Residual stress is one of the main factors affecting the mechanical properties of materials, such as their strength, plasticity and surface integrity. In the hot rolling processes, materials can be deformed nonuniformly due to external influences, such as an uneven mechanical deformation, a temperature change or a phase change, resulting in a flatness defect or residual stress. Measuring residual stress is important for evaluating the quality and safety of steel sheets, but traditional methods such as hole drilling and X-ray diffraction have limitations when measuring residual stress in hot-rolled steel plates. The Barkhausen method, which measures the magnetic field emitted by the material during the application of an alternating magnetic field, can be used to measure residual stress without making additional cuts in the plate. The method was developed to evaluate the residual stress behavior in the cross section of a hot-rolled SAE1010 steel plate and compared to the hole drilling and X-ray diffraction methods.
