Abstract (en)

[origin: EP2690185A1] Provided is an industrially advantageous molybdenum material which is capable of causing secondary recrystallization to occur at a temperature lower than conventional and which, after the secondary recrystallization, can have a structure that comprises giant crystal grains with less grain boundaries and thus is excellent in creep resistance. The molybdenum material has, in at least a part thereof, a portion having a region where the peak intensities of the (110) and (220) diffraction planes are each less than the peak intensity of the (211) diffraction plane, as measured by X-ray diffraction, in a region at a depth of one-fifth of the entire thickness in a plate thickness direction from a surface.
