Effects of annealing temperature on microstructure and mechanical behavior of conventionally and severely deformed Fe–24Ni steel by accumulative roll bonding

In this research, the effects of annealing temperature (500, 550, and 600 °C) on the microstructure and mechanical properties of a conventionally (1 cycle) and severely (6 cycles) deformed Fe–24Ni martensitic steel, processed by accumulative roll bonding (ARB), were investigated. Electron backscatte...
