摘要： A steel sheet with excellent bendability in which the main structure is composed of retained austenite (5-30 area %) and ferrite (no less than 50 area %) such that there exist no more than 40 carbide grains per 2000 nullm2 between the retained austenite and the ferrite. The steel sheet is suitable for automobiles which exhibits bending properties (bendability and tight bendability) even though its strength is as high as 600 to 1400 MPa.

摘要： Chevrel phase materials are used as thermoelectric materials. The Chevrel phase materials are formed as units, and the units include voids between the units. Those voids may be filled with filling elements. The filling elements can be large elements such as lead, or smaller elements such as metals. Exemplary metals may include Cu, Ti, and/or Fe. Different Chevrel phase materials are discussed, including Mo based Chevrel phase materials and Re based Chevrel phase materials.

摘要： A silicon steel sheet having low iron loss of high frequency has a surface layer of the steel sheet which has Si concentration higher than Si concentration of a center portion of the steel sheet. Si concentration of sheet thickness center is 3.4 wt. % or more and Si concentration of the surface layer of the steel sheet is 5 wt. % or more. Si concentration in a surface layer portion is 5 to 8 wt. %. The production method comprises siliconizing treatment and diffusing treatment. Velocity of siliconizing and diffusing are controlled, and Si concentration distribution in the sheet thickness direction of the steel sheet is controlled.
