On the other hand, a variety of states of the iron carbon alloy were un- derstood by the perspective of solid-state phase transformation, and it can provide a train of thought for establishing inner relation between material microstructure and macro properties, also provide a certain reference to the teaching processes of iron carbon phase diagram and sol- id-state phase transformation.
