| Popis: |
A waste of composite material (CM), containing boron-tungsten fibre and aluminium matrix (CM Al-W-B) is investigated. A method of grinding has been used for processing of Al-W-B CM waste. This method has been carried out in several stages in order to obtain a powder with determined particle size. The milled material contains aluminium matrix alloy, boron and tungsten. The morphology of CM Al-W-B particles is described. The mechanism of disintegration and relationship between energy spent for disintegration, and a degree of milling of CM Al-W-B powder, are described. Possible applications of Al-W-B composite powder as a source material for obtaining a new composite ceramics by self-propagating high-temperature synthesis (SHS) are noted. |
