| Abstract: | The uneven amount of globular structure in a very low carbon, low alloy steel in annealed state is studied. After the examination of TEM and EPMA, it is considered that this globular structure arranging in chains and in grain boundaries is carbide and is formed, due to the falling to the pseudo eutectoid zone, in the quick cooling process after hot rolling. In addition, the alloying addition of Ti, V and rare earth element also aggravates the precipitation of carbide. In order to limit the quantity and size of the carbide so as to improve the drawing behavior of the material, the annealing temperature is properly raised to get the equilibrium structure. |
