This is the first investigation on the micromorphology and kinetics evolution of Cr-rich α′
precipitates under Cr composition, irradiation and dislocation with the three-dimensional …

The preferable thermodynamic stability of L1 2 γ'-Co 3 (Al, V) phase and wide γ+ γ'two-
phase region endow the Co-Al-V alloy with great application potential. By introducing the …

The precipitation strengthened Co-based superalloys show the great potential for the next
generation superalloys of aerospace engine, their mechanical properties are associated …

Cobalt-based superalloys with two phase γ/γ′ microstructures offer great promise as
candidates for next-generation high-temperature alloys for applications, such as turbine …

Abstract Fe-Cr-Ni-Al-Ti ferritic superalloy was fabricated by hot isostatic pressing (HIP) of Fe-
Cr-Ni-Al-Ti gas-atomized powders. Three types of precipitates with difference in particle size …

Because the microstructure characteristics of γʹ strengthened cobalt-based superalloys are
critical for anticipated next generation superalloys, the morphological evolution and …

Servicing as the blade of aircraft engine, Ni-based superalloys suffer the axis stress in
working. Driven by the creep strain energy, the γ′-Ni3Al precipitates will be rafted via the …

Cu-rich precipitation ensures high strength and satisfactory ductility of steels at low carbon
content. Although in an over-aged state, it leads to the degradation of mechanical properties …

Abstract The L1 2-γ′-Co 3 (Al, W) phase in Co-based superalloys substantially improves
the creep properties and oxidation resistance. However, the cubic γ′ phase in Co-Al-W …

The volume fraction and rafting degree of the γʹ-Ni 3 Al phase under stress and high
temperature are the key characteristics of mechanical properties in Ni-based superalloys …
