Abstract
Abstract
The electrodeposited nanocrystalline nickel samples were deformed by conventional unidirectional rolling, cross rolling and pack rolling, respectively. The effect of rolling mode on grain growth behavior was investigated by x-ray line profile analysis, transmission electron microscopy observation and microhardness measurement. Quantitative analysis indicated that rolling deformation induced grain growth is associated with grain rotation as well as dislocation activity, no matter what the rolling mode we use. Based on grain rotation induced grain growth, cross rolling induced grain growth is the most obvious, followed by conventional unidirectional rolling and pack rolling.
