PURPOSE:To form the titled granular material on an industrial scale by using an unsealed tube having specific shape as a metallic container incorporating the granular material in the method of rolling said container at the temp. retaining the characteristics of the incorporated material. CONSTITUTION:The amorphous granular material 2 is packed into a metallic tube 1 having the strength enough to resist forming and having >=10 L/D ratio which is the ratio of length L and internal size D and are roll rolled at the retaining temp. characteristics of the granular material 2 without sealing the metallic tube 1. Said internal size D denotes the internal diameter in the case of the metallic tube having a ring shaped cross section and denotes the diameter of the contacted circle of the internal face in the case of the metallic tube having a polygonal cross section. The incorporated granular material is pushed back against the unmeshed part of the tube when the ratio of L/D is too small, but the material is not pushed back in the ratio of >=10 L/D and are therefore subjected to large pressure, by which solid formed articles having high density can be obtd.
