Ultra-Fine Grained Steels discusses results of the New Generation Iron and Steel Materials research project funded over the last ten years. Modern sustainability requirements want that iron and steel must meet four conditions: stronger, longer service life, leading-edge manufacturing technology (low cost, material and energy efficient), and environmentally sound (waste recycling, reduced carbon dioxide emission). Therefore, new generation iron and steel materialsfeaturing ‘double strength and double service life’ are needed (labeled ‘ultra steels’ in Japan). Professor Weng (PhD, Materials Science and Engineering, Pennsylvania State University) has been engaged in the research of new generation structural materials for the last twelve years being Chief Scientist of three consecutive national research programs in China. Thoroughly and systematically describes theoretical achievements in ultra-fine grain steel and its refinement. Discusses progress in related areas of engineering and techology INDICE: 1. Austenite structure and grain refining during deformation in ferrite/pearlite steels. 2. Deformation induced ferrite transformation (DIFT). 3. Microstructure refining of low carbon steels produced by Compact Strip. Production (CSP). 4. Microstructure refining theories of bainitic steels. 5. High strength martensitic steels with grain refining. 6. Carbide-free bainitic/martensitic multi-phase steels. 7. Chemical metallurgy and solidification fundamentals of ultra-fine steels. 8. Fundamentals to homogenize the solidified microstructure. 9. Welding technology of ultra-fine grained steels.
