Abstract Metal 3D printing (3DP), a state-of-the-art manufacturing technology that brings the
potential to fabricate complex structures at low cost and reduced energy consumption, has …

X-ray computer tomography (CT) is fast becoming an accepted tool within the materials
science community for the acquisition of 3D images. Here the authors review the current …

Without post-manufacture HIPing the fatigue life of electron beam melting (EBM) additively
manufactured parts is currently dominated by the presence of porosity, exhibiting large …

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

Hybrid in situ rolled wire+ arc additive manufacturing (HRAM) is a potential 3D printing
method that combines traditional wire and arc additive manufacturing (WAAM) with in situ …

Ti-based alloys are finding ever-increasing applications in biomaterials due to their excellent
mechanical, physical and biological performance. Nowdays, low modulus β-type Ti-based …

The initiation and propagation of short cracks are critical to the detailed understanding of the
failure mechanisms of engineering materials and structures. Therefore, for a safety critical …

Industrial tomography (XCT) is a nondestructive test method that provides information about
spatial distribution of X-ray absorption in the analyzed structures. The aim of this paper was …

The reliability and quality of additively manufactured parts are questionable. The present
study aimed to improve the surface quality and mechanical and tribological properties of a …

This third part of the review on defects as root cause of fatigue failure addresses cavities
(pores, micro-shrinkages, unmelted regions), defective microstructures and microcracks as …
