Impact of Iron Contamination on Liquid Properties and Microstructural Evolution in AlSi20
Advanced Engineering Materials, EarlyView.Recycled aluminum is much more energy conservative and sustainable than primary aluminum. However, the iron contamination in secondary aluminum is vastly responsible for the degradation of the material properties. Herein, it is aimed to evaluate the influence of iron contamination in hypereutectic Al–Si alloy through thermodynamic as well as ...

Advanced Engineering Materials, EarlyView.Al–Si alloys are particularly in demand for automotive and electronic applications, thanks to their excellent wear and thermal properties. Nevertheless, when processed by conventional methods with low cooling rates, the coarse primary Si phases are responsible for increasing brittleness and inducing crack propagation.

Advanced Engineering Materials, EarlyView.In this study, how friction‐welding parameters (rotational speed, etc.) affect the morphology, distribution, and local thickness of the intermetallic compound layer (IMC‐layer) in friction‐welded steel‐aluminum hybrid components is investigated. In the results, it is shown that lower speeds (700 rpm) lead to a more uniform, thinner IMC‐layer (<0.5 μm),

Sprayer testing in the UK – an overview of the National Sprayer Testing Scheme
Julius-Kühn-Archiv, 2015 Sprayer testing commenced in the UK in 1997 when the Agricultural Engineers Association (AEA) launched their industry led testing scheme. AEA members from the sprayer manufacturing and importers sector highlighted the need for such a test, ensuring that application machinery was fit for purpose.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.
