Aluminum Nitride (A1N) - Carbon Nanotube (CNT) composites were prepared to increase the fracture toughness, flexural strength and thermal conductivity of A1N based ceramics by direct in-situ growth of CNTs on the mixtures using Chemical Vapor Deposition (CVD) technique. The A1N- 3 wt% Yttria (Y2O3) base mixtures with in-situ grown CNTs were then spark plasma sintered at 1950°C in vacuum under a pressure of 60MPa. The Vickers Hardness decreased ...

De aanwezigheid van niet-metallische insluitsels is zeer belangrijk tijd ens de productie van hoge kwaliteitstaal, aangezien zij de microstructuu r en de structurele eigenschappen sterk kunnen beïnvloeden. Zij worden v aak beschouwd als schadelijk voor de eindproductkwaliteit en voor de pro ductiviteit van het staalproces, zodat vele industriële inspanningen naa r het verbeteren van insluitselverwijdering worden geleverd. Een andere, positievere ...

Solid state recycling techniques allow the manufacture of high density aluminium alloy parts directly from production scrap. In this paper the environmental impacts associated with ‘meltless’ scrap processing routes based on three different techniques, namely hot extrusion, screw extrusion and spark plasma sintering (SPS), are compared with the corresponding remelting route as reference. Analysis of the obtained results allows clear conclusions ...

Primair aluminium wordt inmiddels reeds meer dan 120 jaar industrieel geproduceerd via het Hall-Héroult proces. Door het gebrek aan duurzame en betaalbare beschermingsmaterialen voor de thermokoppels, is een continue temperatuurmeting vooralsnog onmogelijk. De voornaamste drijvende kracht om wel zon meting mogelijk te maken, bestaat in een betere procescontrole in de Hall-Héroult cel. Het belangrijkste technologische probleem is dat er vandaag ...

The probable emergence of a global aluminium scrap surplus in the coming decade is one of the main incentives for the aluminium recycling industry to invest in new methods and technologies to collect, sort and recycle aluminium scrap. However, due to the considerable uncertainty in the evolution of the global scrap surplus, it is difficult for policymakers and the recycling industry to accurately estimate the economic and environmental ...

The most common accelerated corrosion test used for aluminum brazing sheet is the Sea Water Acidified Accelerated Test (SWAAT). However, still some ambiguity exists, indicating that the test suffers from significant scattering of the results.

Keeping the climatic parameters constant, this study elucidates how the variations of the test results are material dependent. Applying a new statistical reliability evaluation and interpretation ...

Microstructural engineering is at the core of a never ending quest for better performing materials. A key microstructural parameter which affects the physical, mechanical, chemical and biochemical properties of metals is their grain size. The grain size can be reduced considerably by imposing large plastic deformations. In this thesis, a static and dynamic setup, designed and realized within the framework of previous projects, was used to study ...

This paper deals with the non-linear dynamic behavior of thin Aluminium
plates subjected to blast loading. Aluminium plates with grade EN AW-1050A-H24
are studied. The square specimens have an area of interest of 300*300mm2 and
a thickness of 2.5mm. The blast loading is generated using free air blast (FAB)
and explosive driven shock tube (EDST). A numerical finite element model (FEM)
using the commercial software LS-DYNA ...
