摘　　要：利用TEM ,萃取和X ray衍射方法分析了利用形变诱导铁素体和铁素体再结晶机制获得超细晶铁素体的晶内和晶界析出碳化物的成分和析出行为。证明晶内以M3C形成弥散析出 。Utilizing the methods of TEM,extraction and X ray diffraction,the analysis have been done about the chemical component of carbide and behavior of precipitation in the ultra fine grain ferrite and grain boundary by mechanism of deformation induced ferrite and recrystallization mechanism of ferrite.The results proved that the precipitation of dissemination of carbon in grain in the form of M 3C,in grain boundary in the form of layer.The behavior of carbon diffusion is short range.
