Effects of 2 ppm Beryllium on the Oxidation of a 5XXX Aluminum Alloy at Temperatures Between 500 and 750 °C
Smith, Nicholas (Chapter, 2017)The oxidation of molten aluminum has been thoroughly studied, and it is established empirically that beryllium has an inhibiting effect on the oxidation behavior. The aim of this work was to increase the fundamental ... -
Methods of Oxidation Inhibition for Al-Mg Alloys
Smith, Nicholas (Doctoral theses at NTNU;2019:29, Doctoral thesis, 2019)The oxidation of aluminum will occur at any notable oxygen partial pressure. This oxidation can be favorable as it forms a protective layer on the metal surface which prevents further oxidation. However, the addition of a ... -
Oxidation of Liquid Silicon in a Medium Scale Induction Furnace: Examination of the Fuming Rate and Fume Composition
Smith, Nicholas (Master thesis, 2012)The aim of this work was to study the effect of flow rate on the fuming rate/silica flux of liquid silicon in order to gain a better understanding of the silica fuming during industrial ladle refining during silicon ... -
The Mechanism Behind the Oxidation Protection of High Mg Al Alloys with Beryllium
Smith, Nicholas; Kvithyld, Anne; Tranell, Gabriella (Journal article; Peer reviewed, 2018)The addition of beryllium to Al-Mg alloys is known to cause a dramatic decrease in oxidation; however, the mechanism behind this protective effect is not yet fully understood. To aid in finding an alternative to the toxic ... -
XPS Examination of the Oxide-Metal Interface of an Aluminum-Magnesium Alloy Containing Beryllium
Smith, Nicholas; Kvithyld, Anne; Tranell, Gabriella (Chapter, 2018)The addition of beryllium to high magnesium aluminum alloys has long been known to cause a significant decrease in the rate of alloy oxidation. A clear understanding of the fundamental mechanism behind this effect is still ...
