摘要： PROBLEM TO BE SOLVED: To enable a cost reduction through a long life and weight reduction/downsizing of a machine, by a decrease of reduction load.
SOLUTION: The thickness press machine 11 comprises metal dies 13 installed to pinch a slab 12 to be transferred from the top and bottom sides, sliders 14A, 14B which are attached to each of the dies 13 and move the dies 13 applying reduction on the slab 12, and a driving mechanism to drive the sliders 14A, 14B. The sliders 14A, 14B are equipped with cranks 17 that comprise a first shaft 17a arranged rotatably in a round opening in the width direction of the main body 16 and a second narrower shaft 17b having a central axis B eccentric to a central axis A of the first shaft 17a. The central axes A, B of the first shaft 17a and the second shaft 17b respectively are skewed in the plane parallel to the slab in the rectangular direction to the transfer direction of the slab 12. While the second shaft 17b is driven to rotate by the driving mechanism, the slider 14A and 14B apply reduction moving along lines α and β which are skewed to the transfer direction of the slab 12 oppositely each other in the plane parallel to the slab.

摘要： PROBLEM TO BE SOLVED: To provide a metallic material having fine crystal grains with sizes of 2μm or smaller, on an industrial scale.
SOLUTION: This manufacturing method comprises: sandwiching a plastic metal material between dies, at a lower temperature than a recrystallization temperature; and press-forming the metallic material under a high pressure while gradually transporting it. Thereby, the metallic material stores grid distortion which becomes a driving force of recrystallization, forms large-angle boundaries, and consequently forms the fine crystal grains therein.
