Abstract :
Investigations on ball milled pure iron and Fe–0.89C spheroidite alloy powders indicated that the formation of nanoscaled dislocation cells and/or subgrain boundaries is responsible for the grain refinement to nanocrystals. The possible recovery and/or recrystallization due to adiabatic heating induced by high-strain rate is suggested to aid this process.
