Advanced Engineering Materials, EarlyView.Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

A Degradation Function Consistent with Cocks–Ashby Porosity Kinetics [PDF]
, 2018 The load carrying capacity of ductile materials degrades as a function of porosity, stress state and strain-rate. The effect of these variables on porosity kinetics is captured by the Cocks–Ashby model; however, the Cocks–Ashby model does not account for

Simple Model of Capillary Condensation in porous media
, 2002 We employ a simple model to describe the phase behavior of 4He and Ar in a hypothetical porous material consisting of a regular array of infinitely long, solid, parallel cylinders. We find that high porosity geometries exhibit two transitions: from vapor

The Influence of Porosity on Fatigue Crack Initiation in Additively Manufactured Titanium Components
Scientific Reports, 2017 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 amounts of scatter.

Cortical Porosity in Bone [PDF]
, 2014 Osteoporosis (porous bones) is a disease that is characterized by decreased bone strength and increased risk of fracture due to loss of bone strength from decreased bone mass and deterioration of bone micro-architecture. In particular, cortical porosity (CtPo) significantly impacts bone strength and has been associated with the progression of the ...

Advanced Engineering Materials, EarlyView.Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

Advanced Engineering Materials, EarlyView.Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...
