Toughness of Confined Auxetic Foams

open access: yesAdvanced Engineering Materials, EarlyView.
Auxetic (negative Poisson's ratio) materials offer benefits such as impact mitigation, thermal insulation, vibration damping, and reduced shear strain, although their fracture mechanics are largely unexplored. This study investigates damage initiation and propagation in confined re‐entrant auxetic foams from polyurethane via experimental ...

Trade-off between grain weight and grain number and key traits for increasing potential grain weight in CIMCOG population

open access: yes, 2014
To increase breeding efficiency and the grain yield potential of wheat, the trade-off between grain number and grain weight should be minimized by: i) improving the balance between the two main yield components or by ii) increasing grain weight potential. This study aimed to evaluate the trade-off between grain weight and grain number and to assess key

Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

open access: yesAdvanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

open access: yesAdvanced Engineering Materials, EarlyView.
In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for
