(2) When the deformation temperature of 700 ℃, the austenite non-steady state, the reduction rate of more than 6O, then it may cause deformation induced ferrite, resulting in decreased deformation resistance, reflected in the curve, for the second a weak peak pressure F ratio map 5700 ℃, 1.0s' 0 of a curve when the value of the stress appears. (3) organization observed at room temperature deformation of ferrite is similar to the organization, not a real deformation of ferrite, in fact, in the cooling process,<a href="http://www.stivaliuggitalia.org" target="_blank">stivali ugg</a>, the ferrite precipitation along the deformation zone, and grew up along the deformation zone results; When the phase variable reaches 6O more, even if the deformation induced ferrite precipitation, but the deformation is not obvious.
