Precursor, foamed metallic molding, and processes for producing these |
| abstract |
A precursor for a foamed metallic molding is provided which is obtained by compacting a powder mixture obtained by mixing a metallic powder and a blowing-agent powder. The blowing-agent powder is a powder of a carbonate blowing agent. The additive particles to be added besides the metallic powder in forming the precursor have an average particle diameter (d) of 1-20 µm. The volume proportion of the additive particles (f) is 0.003 to 0.100. The content of a hydrogen ingredient in the precursor (X) is 60 ppm or lower. In particular, the precursor satisfies the relationship 15X+?=900 between the hydrogen ingredient content (X) and that average particle-to-particle distance (?) of the additive particles in the precursor which is represented using the average particle diameter (d) and the volume proportion (f) (?=2d(1/f-1)/3). By foam-molding the precursor, first cells which are fine cells having an oxide film on the inner wall surface are evenly formed due to the carbonate blowing agent. This oxide film can inhibit the first cells from uniting with each other or growing. Furthermore, since the hydrogen ingredient content (X) is 60 ppm or lower, second cells, which are coarse cells caused by a hydrogen ingredient, can be inhibited from being formed during the foam molding. Therefore, it is possible to stably obtain a foamed metallic molding evenly having a fine cellular structure. |
