Macroscopic Localization of Plastic Flow in an Additively Produced Bimetal

The kinetics of macroscopic strain localization in a bimetal formed by electron-beam cladding of a 09G2S low-carbon steel wire on a St.3 substrate is studied. The mechanical uniaxial-tension tests of flat samples are carried out at a constant rate at room temperature. The mechanical properties and plastic flow stages in the bimetal are compared with those of the starting materials. The kinetics of the plastic strain localization zones in different bimetal layers is studied by digital speckle photography.
