Advanced Engineering Materials, EarlyView.High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

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.
