Methods of Compaction of the Al–B–W Powder Composition in a Metal Shell

Resumo

The compaction of powder of the Al–B–W in a copper shell is considered in this article. This material is supposed to fabricate, for example, grinding tool components or radiation protection elements. For this purpose, it is necessary to fabricate both short and long semifinished products, which requires the development and testing of various process flowsheets (methods) based on using static and dynamic loads, as well as their combinations. An analysis of experimental results shows the reality and possibility to implement the proposed flowsheets for fabricating tubular semifinished products of various sizes. The entire chain of their manufacture is considered from the production of powders to their compaction and sintering. To assess the quality of the sintered powder composition, metallographic investigations are performed. Their results show an almost complete absence of pores. Technology is developed that ensures the fabrication of new products, including long ones, from the Al–B–W powder composition.
