Inspection reliability of small-scale defects, targeting dimensions below 100 µm, is crucial for
structural safety of critical components in high-value applications. Early defects are often …

Since aviation sector equipment has evolved to very long-life application conditions, critical
components and structures are regularly subjected to complex environments and applied …

Welded structures in aero-engines commonly operate in high-temperature environments,
making them susceptible to reduced fatigue life and premature failure due to welding defects …

Tensile and fatigue behaviors of selective laser melted titanium alloy were investigated in
the as-built condition. The alloy has a high defect density, and its tensile properties are …

The very long life fatigue failure mechanism of welded joints for titanium alloy at 400℃ has
been investigated. The results show that the welded joint has a nonhomogeneous …

Very high cycle fatigue behavior of electron beam welded TC17 titanium alloy joints under
different stress ratios was investigated. The results revealed that the welded joints exhibited …

Electron beam welding (EBW) is suitable for joining titanium alloys. However, the utilization
of EBW leads to an uneven microstructure within the weldment due to the rapid solidification …

The design life of welded structures and components extends into the very high cycle fatigue
(VHCF) regime across various applications. However, the availability of data on the fatigue …

It is suspected early that the ultra-slow crack propagation in fine-granular-area (FGA) may be
sensitive to the internal vacuum-like environment. In other words, fatigue failure in the very …

The effects of pore size and position on the local stress are characterized by a parameter P
dH. This parameter is then introduced into the elastic fatigue damage model to equivalently …
