The microstructure, thermal and mechanical stability of Ni-based single crystalline
superalloys depend strongly on the alloying elements and their concentrations. Alloying has …

Abstract Dynamic Strain Ageing (DSA) has reached widespread acceptance since its
proposal in the 1940's as the mechanism behind the Portevin-Le Chatelier effect in ferritic …

This article describes the development of a new multi-platform software program called
JMatPro for calculating the properties and behavior of multi-component alloys. These …

Most modern single crystal alloys are thermodynamically unstable with respect to the
formation of topologically close-packed (TCP) phases due to the addition of solid solution …

Creep tests at 900° C, 392 MPa and 1100° C, 137 MPa were performed on a third
generation Ni-base single-crystal superalloy TMS-75 and its γ/γ′ tie line alloys. These tie …

Owing to restrictions on forming dimensions, laser powder bed fusion (LPBF) components
will continue to require laser welding in the future. The post-weld thermal cracking of LPBF …

Nickel-based single crystal superalloys (Ni-SXs) are of great interests in aircraft industry due
to their excellent high temperature creep strength deriving from the rigid gamma/gamma …

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 …

Over the years, diffusion aluminide bond coats have been widely used for providing
oxidation resistance to Ni-base superalloy components of advanced gas turbine engines …

The formation of topologically close-packed (TCP) phases in nickel-base single crystal
superalloys causes considerable degradation of the mechanical properties. It has recently …
