Fatigue performance in both traditional and additively manufactured materials is severely
affected by the presence of defects, which deserve special attention to ensure the in-service …

Powder metallurgy (PM) Ni-based superalloys are widely used for aeroengine turbine disc
applications due to their excellent mechanical properties and good corrosion resistance at …

A non weldable nickel-based superalloy was fabricated by powder bed-based selective
electron beam melting (S-EBM). The as-built samples exhibit a heterogeneous …

During deformation of aluminum (Al) alloys, there are three kinds of voids being formed by
distinct mechanisms, ie, matrix-cracking voids (MCVs), particle-cracking voids (PCVs), and …

Fatigue crack nucleation in a powder metallurgy produced nickel alloy containing a non-
metallic inclusion has been investigated through integrated small-scale bend testing …

The microstructural configurations that favor early strain localization and fatigue crack
initiation at intermediate and high temperature (400° C–650° C) have been investigated …

Traditional probabilistic fatigue life test requires long time, a large number of samples and
high cost due to dispersion, randomness and complexity. A new data-driven probabilistic …

Understanding the deformation, strengthening and failure mechanisms in polycrystalline
nickel-base superalloys is necessary to develop next generation alloys for application in …

Single crystal (CMSX4) and oligocrystal (MAR002) nickel have been studied using three-
point beam bending under conditions of cyclic loading. SEM images have enabled …

Crack initiation at inclusions is a dominant, unavoidable and life-limiting failure mechanism
of important structural materials. Fatigue progresses in a complex manner to find the …
