Fine Grain

Study of grain refinement has developed to improving the mechanical properties of low carbon steel. Wedge shaped slab of low carbon steel were deformed through warm rolling methods of 500, 550, and 600oC to produce a finer ferrite grains. The thickness reduction of deformation is 80, 75, 67 and 50% .Dynamic recrystallizations were confirmed at warm working temperature in this study. Grains size which obtained through this process could improve the hardness and its mechanical properties and also its performance in corrosive environment. The smallest grain size was obtain from 80% deformation is 5.2 µm and the tensile strength is 817.65 MPa. Its gives the evidence that warm rolling can use to produce the fine grain at warm temperature of 600oC.

Microstructure Morphology

Warm rolled deformation is one of deformation technique to improve the strength of steels through the refining grain size of ferritic microstructure. In application, low carbon steel which used in structural industry need some protection against corrosion attack, cathodic protection is usually applied combining with coating. Cathodic protection creates reduction reaction which produces hydrogen, and the hydrogen atom may diffuse into the crystal lattice lead to the Hydrogen Induced Cracking. The present study is to observe the morphology of microstructure influenced by hydrogen charging as the source of hydrogen which attacks the steel surface, and observed by Optical Microscopy and Scanning Electron Microscopy. After warm rolling of 650oC and 35% deformation, ferrite grain size is smaller than bulk material and the hardness value increasing. After tensile test of hydrogen charged steel found the ductile fracture, it means the smaller the ferrite grains size, the resistance of hydrogen attack is increase.
