Thermomechanical processing of an aluminium casting alloy for thixoforming

Journal of Alloys and Compounds, 2009
Abstract Thermomechanical processing of Al–Si casting alloys may be attractive when the material of choice for a large number of small parts to be thixoformed is a higher silicon grade aluminium alloy. With particle dispersion characteristics unique to hot-worked metals and a matrix no longer dendritic owing to extensive plastic flow and welding of α-

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

Evaluation of the Efficiency of a Biobased Reactive Plasticizer on the Morphology and Properties of Sustainable Flexible Films Based on Poly(Lactic Acid) (PLA) Produced by Blown Film Extrusion

Journal of Applied Polymer Science, EarlyView.
A comparative investigation of two epoxy additives derived from cardanol (NC513 and NC514s) for production of films based on poly (lactic acid) (PLA), acetyl tributyl citrate (ATBC), and poly (butylene adipate‐co‐terephthalate) (PBAT) clarified their distinct roles, with NC513 mainly acting as a plasticizer, reducing viscosity and enhancing ductility ...

Grain refinement through controlled thermomechanical processing

, 2005
The major challenge for thermomechanical processing is to extend grain refinement towards lower average grain sizes. However, there is also a need to provide a better understanding of the mechanisms through which the refinement processes proceed.

Transient thermal modelling of green anode cooling in the aluminium industry

The Canadian Journal of Chemical Engineering, EarlyView.
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before
