Abstract：This paper introduces a new research project granted by national basic research program of China (973 program), which is the third phase for New Generation Steel research. The project aims to systematically investigate the microstructure evolution phenomena in steels and to form the new microstructure control technologies for high performances, by which the safety of steels in service could be eventually improved remarkably. The issues such as steel metallurgy for ultra clean and ultra homogeneous microstructures, phase transformation mechanisms of meta-stable austenite subject to temperature and load changes, carbon diffusion during transformation, multi-scale characterization of transformed microstructures, and microstructure stability in the circumstances of temperature, load and corrosion in service. It is expected to develop the theory of microstructure control featured by Multi-phase, Meta-stable and Multi-scale (M3). It is also to form the prototype technologies for manufacturing high performance steels such as the third generation high strength low alloy steel, the third generation auto sheet steel, and the third generation heat resistant martensitic steels. It will provide the fundamentals for improving safety of steels in service for infrastructures, automobiles and fossil power station.
