Autowave Process of Plastic Flow in Cu-Ni Alloys

This work is aimed at studying the effect of Ni content in Cu-Ni alloys on the localization of plastic flow under uniaxial tension. The regularities of localized plastic flow at different stages of work hardening are investigated at different Ni contents in the solid solution via speckle photography method. Particular attention is paid to the effect of Ni content on the duration of the parabolic work hardening stages in alloys. The spatial period of plastic flow localization (the length of the localized autowave) as a function of Ni content in alloys is established as well.
