| 中文摘要 | The tensile properties of ultra-fine grained ordered FeCo-2V have been investigated as a function of testing temperature. Samples with grain sizes of 100, 150 and 290 nm have been tested at temperatures ranging from 25 to 500 degreesC. Extremely high yield strengths (up to 2.1 GPa) were measured at room temperature with appreciable ductility of between 3 and 13%. These strengths were found to decline only gradually as the testing temperature was increased to 400 degreesC, while ductility was generally enhanced, up to 22%. The high strengths are attributed to grain boundary strengthening that is particularly effective due to ordering. Measured ductility was dependent on the relative values of yield strength, fracture strength and work hardening rate. Discontinuous yielding and appreciable Luders strain (3-6%) were observed and were dependent on the initial structure and on the testing temperature. (C) 2003 Acta Materialia Inc.
