When the particle size is decreased by milling, the onset and completion temperatures of the abnormal growth and the final grain size are decreased. The abnormal grains growing during isothermal heating are nearly tetrakaidecahedral in shape, whereas those growing during rising temperature have the morphology of an edge-cut cube.
