Powder metallurgy (PM) Ni-based superalloys are widely used for aeroengine turbine disc
applications due to their excellent mechanical properties and good corrosion resistance at …

In this review, the role of oxidation of chromia-forming Ni-based superalloys used for rotor
disc applications in gas turbines is examined. A detailed review of the oxidation …

The loss of ductility in the high strength polycrystalline superalloy 720Li is studied in air
between room temperature and 1000° C. Tensile ductility is influenced profoundly by the …

Many high-temperature rotating components are always subjected to complex loading
waveforms, arising the concerns for various damage modes simultaneously. The aim of the …

Cyclic deformation of polycrystalline Ni-based superalloys leads to cyclic hardening
followed by softening, in terms of the mechanical response. A micromechanical constitutive …

Characterizing the transition from a crack-free to a cracked state remains a challenging topic
in fatigue. Mg-rare earth alloys, containing the long-period stacking ordered (LPSO) phase …

The objective of this study was to investigate the cyclic deformation mechanisms at the
microstructural level and their correlation with the initiation and early propagation of small …

Fatigue failure processes in metallic materials are closely related to the evolution of strain
localisation under cyclic loading. Characterisation of this strain localisation is important in …

A crystal plasticity modeling framework is developed and used in combination with
experiments for studying the deformation behavior of a polycrystalline Ni-based superalloy …

Transition from internal to surface crack initiation is controlled by oxidation assisted fatigue-
crack process in the very-high-cycle fatigue regime. Between 760 and 1000° C, single crack …
