There are several facets of aluminum when it comes to sustainability. While it helps to save
fuel due to its low density, producing it from ores is very energy-intensive. Recycling it shifts …

This is the first of three overviews on failure of metals. Here, brittle and ductile failure under
monotonic loadings are addressed within the context of the local approach to fracture. In this …

Hydrogen pores in laser additive manufacturing (LAM) aluminum alloys have long been a
major challenge for its application. In this study, the formation mechanisms of hydrogen …

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 …

The application of wire+ arc additively manufactured (WAAM) aluminum alloys has been
restricted by the porosity defect, which is generally detrimental to the mechanical properties …

Given its detrimental influence on mechanical properties, porosity defect is a major problem
for wire+ arc additively manufactured (WAAM) Al components. We performed X-ray …

We reported the precipitation phenomena and strengthening mechanism of Al–Cu alloys
deposited by in-situ rolled wire-arc additive manufacture (WAAM) technology. The results …

Hydrogen repartitioning and the related embrittlement behavior were characterized by
studying Al–Zn–Mg–Cu aluminum alloys with different intermetallic particle contents. Using …

Damage in metallic materials usually originates at grain boundaries where deformation
leads to local strain incompatibility and stress concentration. Characteristics of a grain …

We directly captured, classified, and evaluated 3D particle debonding and fracture behavior
in a H-charged 7075 Al alloy throughout the entire tensile deformation using synchrotron X …
