Physical metallurgy in steels

The strength of steel has surprisingly wide span.For example, a steel bottle-can has strength around 200MPa, but its strength can be increased to around 2000MPa by proper addition of alloy elements and heat treatment. Difference of strength by an order of magnitude is a unique feature of steel and that is why it has been used as major material in various industries. Actually, the wide span of strength in steel originates from the flexibility of microstructure. Steel may be the only material which has five distinctive microstructural constituent with characteristic properties. We are trying to control the microstructure of steels for unexplored properties by taking full advantage of microstructure flexibility. Thermo-mechanical treatment is a powerful tool for manipulating the microstructure, but a precise control of the microstructure usually requires deeper understanding on thermodynamics and kinetics of phase transformation.

Next generation higher-performance steels

There are diverse requirements for higher-performance steel products, in particular, from the transportation and energy industries. To cope with the demand, a concept of performance-oriented alloy and microstructure design will be essential. In steel research, the application of computational metallurgy for development of new steel product seems to go in rather slower manner compared with other fields. One of the reasons is that steel has a complicated microstructural hierarchy with various aspects of application properties. The materials design in steel is tricky without an insight on the microstructure scale critical to obtain the desired properties. We are trying to tackle the problem by combining the traditional view of physical metallurgy principles with the computational approach, which is expected to provides a synergetic effect for the successful development of next generation higher-performance steels.
