Cyclic Deformation and Recrystallization

This lecture covers topics related to cyclic deformation, including the stabilized state in cyclic strain, the role of temperature, strain rate, and stacking fault energy, and the evolution of dislocation structures. It also discusses the cyclic hardening of nickel and silver, the influence of different laws to describe the cycle, and the measurement of mechanical resistance to fatigue. Furthermore, it explores the evolution of dislocation structures during cyclic deformation and the kinetics of recrystallization, focusing on the growth of subgrains and grains. The lecture delves into the impact of alloy elements, the spatial distribution of solutes, and the mobility of subgrains and grain boundaries.
