Effect of Laser Shock Peening Parameters on Residual Stresses and Corrosion Fatigue of AA5083 (open access)

Effect of Laser Shock Peening Parameters on Residual Stresses and Corrosion Fatigue of AA5083

Article examining Aluminium alloy 5083 subjected to Laser Shock Peening both with (LSP) and without protective coating (LPwC) at multiple pulse densities. A second LPwC treatment was conducted fully submersed under water, in addition to the standard laminar water flow condition. Results show that compressive residual stresses were generated in all cases, although their character varied depending on the peening strategy and method of confinement.

Ordering-mediated local nano-clustering results in unusually large Hall-Petch strengthening coefficients in high entropy alloys (open access)

Ordering-mediated local nano-clustering results in unusually large Hall-Petch strengthening coefficients in high entropy alloys

This article reports a dramatic increase in the grain boundary strengthening or Hall-Petch coefficient, K, by systematically investigating the effect of Al addition on tensile yield strength in CoFeNi and CoCrFeNi high entropy alloys (HEAs) or complex concentrated alloys (CCAs). Such a trend is attributed to the ordering mediated nano-clustering in Al containing HEA/CCAs.

Effect of Polymer Removal on the Morphology and Phase of the Nanoparticles in All-Inorganic Heterostructures Synthesized via Two-Step Polymer Infiltration

This article uses iron oxide/alumina heterostructures formed by two-step infiltration of polystyrene-block-polyvinyl pyridine block copolymer with iron and aluminum precursors from the solution and vapor-phases, respectively, to show that the phase and morphology of iron oxide nanoparticles dramatically depend on the approach used to remove the polymer. The article extends the boundaries of structure manipulations in multicomponent heterostructures synthesized using polymer infiltration synthesis and their properties.

Bioresorbable stent to manage congenital heart defects in children

This article assembles large, pediatric-sized stents (Ø10 - Ø20 mm) from poly(L-lactide) fibers (DH-BDS) at two thicknesses, 250 µm and 300 µm. DH-BDS exhibiting hoop strength similar to metal stents and demonstrating minimal degradation and strength loss over the first year before completely disappearing within 3 to 4.5 years show promise as a pediatric interventional alternative to current strategies.

First principles computation of composition dependent elastic constants of omega in titanium alloys: implications on mechanical behavior

Article on the poor mechanical properties of Ti alloys. The study shows that the elastic properties of the ω-phase can be systematically varied as a function of its composition to enhance both the ductility and strength of the Ti-alloy. Furthermore, that ω precipitates are not intrinsically embrittling and detrimental and that Ti-alloys can be created with both good ductility and strength by tailoring ω precipitates' composition instead of completely eliminating them.
