"A metal matrix dissolution technique has been improved to assess a breakage of short fibres during creep of Al-7Si-3Cu-1Mg alloy based metal matrix composite (MMC). Short reinforcing Saffil fibres (15vol%), originally embedded in the metal matrix (85vol%), were separated from the chemical solution using centrifugal forces and the evaluation of their length was assisted by a PC-based image analysis procedure. Results show unambiguously that short ceramic fibres do break during creep at 623 K. The distribution of the fibre length after 2% of creep strain peaks at the length value that is approximately half of the one observed before creep. This result has not only been found for the population of fibres originally situated close to the fracture surface but also for the fibre population extracted from the crept specimen gauge length far from fracture. Consequently, it is concluded that the fibre breakage process is rather uniform in the specimen gauge length during creep of the investigated MMC. It is al" . . . . . "The Institute of Materials" .
