摘要

Abstract

The yield strength of the [001]-orientated single-crystal nickel-based superalloy PWA1483 is investigated under tension/compression at 1000 and 1100 °C. We found that the compressive yield strength is larger than the tensile strength. Microstructural observations disclose that the dominant deformation modes are stacking fault shearing and microtwinning in compression at 1000 °C

whereas dislocation climb controls the plastic deformation under the other three deformation conditions

although the above two processes also occur. Based on these results

it is deemed that the frequent occurrence of 112{111} slip accounts for the tension/compression asymmetry in the yield strength of PWA1483 at high temperatures.
