Compaction methods for Al—B—W powder composition in a metal shell

The article considers the compaction of Al-B-W system powder in a copper shell. Such material is supposed to be used, for example, to produce grinding tool components or radiation protection elements. For this purpose, it is necessary to obtain both short and long-length semi-finished products which required the development and testing of various technological schemes (technologies) based on the use of static, dynamic loads and their combinations. Analysis of the results of the experiments showed reality and the possibility of implementing the proposed schemes to obtain tubular semi-finished products of different sizes. The whole chain of their manufacturing from powder production to compaction and sintering is considered. Metallographic studies conducted to assess the quality of sintered powder composition demonstrated almost full absence of pores. The technology is developed to ensure making new products, including long-length ones, from powder composition.
