Grain boundaries (GBs) are central defects for describing polycrystalline materials, and
playing major role in a wide-range of physical properties of polycrystals. Control over GB …

Grain boundaries influence mechanical, functional, and kinetic properties of metallic alloys.
They can be manipulated via solute decoration enabling changes in energy, mobility …

Fatigue performances of critical structures are strongly affected by the microstructural (eg
grain, defect, inclusion, etc.) size effect, and it is thus important to quantify their detrimental …

The fatigue life of a component can be expressed as the sum of two segments of life:(a) the
number of loading cycles required to initiate a crack and (b) the number of cycles it takes that …

Abstract Laser Melting Deposition (LMD) of Inconel 738 (IN738) superalloy is a promising
process for the remanufacturing of gas turbines and aerospace engines, but the cracking …

High-resolution digital image correlation was employed to analyze the occurrence of slip
transfer across grain boundaries in pure Ti. The microstructure was characterized in 3D …

The interaction between slip bands and grain boundaries in commercial-purity titanium was
examined using cross-correlation-based electron backscatter diffraction. At a low strain …

Irreversible deformation in relation to the microstructure was investigated for a
polycrystalline Ni-based superalloy (Alloy 718) from room temperature to 650° C using high …

Powder metallurgy (PM) Ni-based superalloys are widely used for aeroengine turbine disc
