Deformation micro-twinning arising at high temperatures in a Ni-Co-based superalloy

文献摘要：

Deformation twinning is an important deformation mechanism in nickel-based superalloys.For super-alloys,deformation twins are generally observed at low or intermediate temperatures and high strain rates;however,the appearance of microtwins(MTs)at high temperatures has rarely been reported.In this study,transmission electron microscopy(TEM)was used to study MT formation in Ni-Co-based su-peralloys following compression at 1120℃/1 s-1.The deformation behavior was discussed in detail to reveal the mechanism of MT formation.The twinning mechanism at elevated temperatures was theoret-ically attributed to the low stacking fault energy(SFE)and poor dislocation-driven deformations caused by the high strain rate in specific directions.
