Observations par microscopie electronique en transmission a 200 kV de defauts d'empilement aux precipites γ' pour l'alliage MA6000 apres deformation a 760 C et 790 C
Oxide d ispers ion s t r e n g t h e n i n g (ODS) has been success fu l ly combined with -f' precipi ta t ion ha rden ing in the superal loy MA 6000. The development of MA 6000 is s t rong ly… (More)
ABSTRACT The deformation mechanism of PM Astroloy in LFC experiments has been investigated. At low temperature (300 °C) and high strain rate (10-2s-1) planar character of slip is demonstrated by… (More)
ABSTRACT Cu2NiZn shows an anomalous temperature dependence of the workhardening due to severe (100) cross-slip. A maximum occurs near 375 K. The samples with cube-type domains do exhibit this effect… (More)
