Oxidation-free granulation of metals
- 20 Downloads
It was demonstrated that it is possible to obtain high-quality spherical granules from different alloys with different densities.
The strength characteristics at room and elevated temperatures increase considerable as the result of granulation.
A relationship was found between the granulometric composition and the physical properties of alloys and the parameters of the melting process.
Preliminary analysis of the microstructure of granules of different alloys indicates a fine dendritic structure and the absence of large precipitates of second phase.
The granules obtained by the given method are promising original materials for producing semifinished products with excellent properties, composite materials, and porous parts such as filters.
