4. Conclusions The proposed study reveals the characteristic behaviors of jump deformation in AMg6 alloy when subjected to uniaxial tension under mild loading conditions. A quantitative relationship was established between the increase in deformation and the dimensions of the breaking dispersed phases. The paper proposes a method for predicting the AMg6 alloy jump deformation at T=293 K by referencing a histogram of the initial dispersoid distribution in the material and by proposing dependencies on the strengthening regions between jumps.
