Precipitate dissolution during deformation induced twin thickening in a CoNi-base superalloy subject to creep
Abstract
The tensile creep performance of a polycrystalline Co/Ni-base superalloy with a multimodal γ distribution has been examined at 800◦C and 300 MPa. The rupture life of the alloy is comparable to that of RR1000 tested under similar conditions. Microstructural examination of the alloy after testing revealed the presence of continuous γ precipitates and M23C6 carbides along the grain boundaries. Intragranularly, coarsening of the secondary γ precipitates occurred at the expense of the fine tertiary γ . Long planar deformation bands, free of γ , were also observed to traverse individual grains. Examination of the deformation bands confirmed that they were microtwins. Long sections of the microtwins examined were depleted of γ stabilising elements across their entire width, suggesting that certain alloy compositions are susceptible to precipitate dissolution during twin thickening. A mechanism for the dissolution of the precipitates is suggested based on the Kolbe reordering mechanism.
