Additive manufacturing (AM) of metallic components offers many advantages over
conventional manufacturing methods, most notably design freedom at little material waste …

Metallic materials have enabled technological progress over thousands of years. The
accelerated demand for structural (that is, load-bearing) alloys in key sectors such as …

The manufacturing defects introduced by selective laser melting typically lead to lower
fatigue strength and a larger variation in fatigue life compared to conventionally …

Microstructural features and defects arising from selective laser melting (SLM) determine the
in-service performance of additively manufactured near-net-shape components. Here the …

Under external loadings, notched components always show varying degrees of stress
concentration. Accordingly, different kinds of approaches have been presented to …

The effects of environment (in air and 3.5 wt% NaCl solution) and artificially-induced surface
scratches are investigated on the fatigue properties of railway EA4T (also called 25CrMo4) …

CrCoNi-based high-entropy alloys have demonstrated outstanding mechanical properties,
particularly at cryogenic temperatures. Here we investigate the fatigue-crack propagation …

Damage-tolerant models for fatigue life estimation rely on fracture mechanics principles to
model fatigue crack initiation and growth. In Laser-Based Powder Bed Fusion (LPBF) …

Fatigue in metals involves gradual failure through incremental propagation of cracks under
repetitive mechanical load. In structural applications, fatigue accounts for up to 90% of in …

Very-high-cycle fatigue (VHCF) is the fatigue damage and failure beyond 10 7 loading
cycles. Crack initiation of VHCF for metallic materials is commonly from the interior of …
