Nickel-based superalloys are used in gas turbines due to their mechanical properties at high
temperatures. Increasing demand for higher efficient engines has led to the development of …

Ni-based single crystal superalloys exhibit superb mechanical strength, particularly, creep
resistance at elevated temperature. The unique microstructure, which is consisted of γ γ and …

This paper summarises the regulation mechanism of the traditional and emerging surface
strengthening treatments–mechanical shot peening (SP) and laser shock processing (LSP) …

Designing of new alloys requires a detailed understanding of the roles played by each
alloying element, yet a systematic investigation of the solid-solution strengthening effects in …

In-situ high energy diffraction microscopy (HEDM) experiments are carried out to analyze the
state of combined bending and tension in a Ti-7Al alloy under room temperature creep …

The lattice misfit between γ and γ′ phase in Ni-based single crystal superalloys plays a
critical role for microstructural stability and high-temperature creep and fatigue resistance …

Aero-engine turbine blades may suffer overheating during service, which can result in
severe microstructural and mechanical degradation within tens of seconds. In this study, the …

Very high temperature creep properties of twelve different Ni-based single crystal
superalloys have been investigated at 1250° C and under different initial applied stresses …

Microstructural and chemical heterogeneities may exacerbate the high-temperature
mechanical properties of single crystal turbine blades. The evolution of microstructure and …

In this study, thermal cycling creep tests under (950° C/15 min+ 1100° C/1 min)/100 MPa
were performed to simulate the overheating service condition of a directionally solidified …
