| 内容記述 | High-purity molybdenum single crystals of mid-orientation, doped with carbon, are hardness and tensile tested after various heat-treatments. Two-stage age-hardening is observed on isochronal aging. The two stages correspond to the two stages in resistivity change and are considered to be due to the formation of carbon clusters. The age-hardened crystals containing more than 10 at. ppm carbon are brittle and cleaved along approximately {100} in a tensile test at 77 K. Above 179 K, an aged specimen containing 300 at. ppm carbon is ductile. Work-softening is observed in as-quenched specimens tested at 77 K and in aged crystals with more than 300 at. ppm carbon tested at the ductile temperature range. The yield stresses of brittle crystals and those showing work-softening are larger than 1100 MN m^<-2>, which is approximately the maximum flow stress of a pure molybdenum crystal. Aged specimens with less than 10 at. ppm carbon show lower yield and flow stresses than the pure crystal. | |||||||||||
