摘要: Abstract Creep fracture of a composite based on an aluminum matrix reinforced by 4 vol.% Al 4 C 3 was studied at temperatures 623 and 723 K small punch testing with constant force. The tested in state after equal channel angular pressing (ECAP) two passes route as final operation. It found that the time to inversely proportional minimum deflection rate similar manner corresponding quantities conventional creep tests. fractured surfaces materials had largely intercrystalline character.
