The precipitation of topologically close-packed (TCP) phases is the result of microstructure
instabilities of Ni-based superalloys. This review seeks to comprehensively collate all the …

Recent years have seen an increased application of small-scale uniaxial testing—
microcompression—to the study of plasticity in macroscopically brittle materials. By …

To investigate influences of Ta content on microstructural stability during thermal exposure
at 900° C (up to 3000 h) and creep properties at 980° C/163 MPa in Ni-based SX superalloy …

Based on crystal slip theory, the rafting of γ′ precipitate phases, the atomic diffusion of Re,
the growth mechanism of topologically close-packed (TCP) phases and the microcrack …

This study explores the effects of Re and Ta interactions on TCP (topologically close-
packed) phase precipitation in experimental alloys under long-term thermal exposure. TCP …

Precipitation behavior of a topologically close packed (TCP) μ phase as well as its role
during the creep deformation in single crystal superalloy CMSX-4 have been investigated …

The role of topologically close packed (TCP) phases in deformation of superalloys and
steels is still not fully resolved. In particular, the intrinsic deformation mechanisms of these …

Creep damage by void nucleation and growth limits the lifetime of components subjected to
mechanical loads at high temperatures. For the first time, the porosity of a Ni-based single …

Oxidation and interdiffusion behaviors of Ni-based single crystal superalloy DD98M with
nominal compositions Ni–5.0 Co–6.0 Cr–6.3 Al–6.0 W–2.0 Mo–6.0 Ta–1.0 Ti (in wt.%) and …

Topologically close packed phases, among them the μ-phase studied here, are commonly
considered as being hard and brittle due to their close packed and complex structure …
