Analysis shows changes in yield strength for magnesium and steel strips, highlighting deformation effects.
The study of the effect of elastic-plastic alternating deformation on the mechanical properties of magnesium strips and low-carbon steel strips after processing on a roller straightening machine was carried out. The application of the strengthening process in 1 and 3 passes does not change the geometry of the strips. The yield strength of steel increases and the yield strength of magnesium decreases; at the same time, the yield plateau disappears on the tensile curve of steel samples, and a region similar to the easy slip stage in a single crystal appears on the tensile curve of magnesium samples after the elasticity stage. For an integral assessment of the effect of alternating deformation on the material and to determine its resistance to deformation, flow curves were constructed using the Nadai model.
