Mechanism behind the Inhibiting Effect of CO2 on the Oxidation of Al−Mg Alloys
(Peer reviewed; Journal article, 2018)Al–Mg alloys are known to suffer from problematic oxidation during melting, refining, and casting. The use of a CO2/air cover gas is known to minimize this oxidation; however, a mechanistic understanding of the beneficial ... -
The Mechanism Behind the Oxidation Protection of High Mg Al Alloys with Beryllium
(Peer reviewed; Journal article, 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 ... -
Mechanisms and Thermochemistry of Reactions of SiO and Si2O2 with OH and H2O
(Peer reviewed; Journal article, 2023)This paper reports on computational studies of gas-phase reactions of SiO and Si2O2. The oxidation of SiO can initiate efficient formation of silica or silicate dust particles in a wide range of environments. Both OH ... -
Mechanisms of SiO oxidation: Implications for dust formation
(Peer reviewed; Journal article, 2023)Reactions of SiO molecules have been postulated to initiate efficient formation of silicate dust particles in outflows around dying (AGB) stars. Both OH radicals and H2O molecules can be present in these environments and ... -
