Abstract: A method of thermo-mechanically processing a preform composed of tool steel and a tool to modify a workpiece. The preform has a region containing austenite. The method comprises establishing the region at a process temperature between a martensitic start temperature and a stable austenitic temperature. While at the process temperature, the region is deformed to change an outer dimension and to modify the microstructure to a depth of 1 millimeter or more. The tool comprises a member composed of tool steel. The member includes a first region that extends from the outer surface to a depth of greater than 1 millimeter and a second region. The first region includes a plurality of grains having an average misorientation angle greater than about 34°, an average grain size that is at least 10% smaller than the second region, and has a different grain orientation than the second region.

Abstract: Orientation degree and smoothness of a substrate surface better than those of conventional ones are provided in a textured substrate for epitaxial thin film growth. The present invention is a textured substrate for epitaxial film formation, including a crystal orientation improving layer made of a metal thin film of 1 to 5000 nm in thickness on the surface of the textured substrate for epitaxial film formation having a textured metal layer at least on one surface, wherein differences between orientation degrees (Δφ and Δω) in the textured metal layer surface and orientation degrees (Δφ and Δω) in the crystal orientation improving layer surface are both 0.1 to 3.0°. Further, when another metal different from the metal constituting this textured substrate crystal orientation improving layer is added equivalent to a thin film which is 30 nm or less, and subsequently is subjected to heat treatment, the smoothness of that surface can be improved. At this time, the surface roughness of the substrate surface becomes 20 nm or less.

Abstract: In a grain-oriented electrical steel sheet having phosphate-based coatings, which contain no chromium and which impart a tension, on the surfaces of a steel sheet with ceramic underlying films therebetween, the coating amount of oxygen in the underlying film is 2.0 g/m2 or more and 3.5 g/m2 or less relative to both surfaces of the steel sheet. Consequently, a grain-oriented electrical steel sheet with a chromium-less coating is provided. The resulting steel sheet has coating properties at the same level as those of a steel sheet with chromium-containing coatings and realizes high hygroscopicity resistance and a low iron loss without variations.
