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 …

This is the first of three overviews on failure of metals. Here, brittle and ductile failure under
monotonic loadings are addressed within the context of the local approach to fracture. In this …

Aluminum alloys play an important role in circular metallurgy due to their good recyclability
and 95% energy gain when made from scrap. Their low density and high strength translate …

The crystallographic orientation, tensile behavior, fracture mechanism, hardness, and elastic
modulus of a single-crystal CoCrFeNiAl 0.3 high-entropy alloy (HEA) successfully …

The creep tests for Ni-based single-crystal superalloy are carried out under 980° C, and the
microstructure at the crack tip is characterized at micro-and nano-scales. Numerous γ'phase …

Weight reduction and advanced cooling schemes to improve aircraft engine efficiency drive
the design of turbine blades toward thin-walled structures. The decrease of wall thickness …

Early stages of high-temperature oxidation and hot corrosion of Ni-based single-crystal
superalloy were studied at 900° C by introducing sulfate coating. Detailed elemental and …

Amorphous Al 2 O 3 coating was prepared on Ni-based single crystal superalloy via atomic
layer deposition (ALD) for high temperature oxidation protection. The oxygen inward …

An elastoviscoplastic model is formulated at finite strains for porous single crystals. The
model extends the yield function developed by Han et al.(2013) for porous single crystals at …

A rate-(in) dependent constitutive model for porous single crystals with arbitrary crystal
anisotropy (eg, FCC, BCC, HCP, etc.) containing general ellipsoidal voids is developed. The …
