Abstract Gas porosity is a major factor in the quality and reliability of castings. The major cause of gas porosity in castings is the evolution of dissolved gases from melting and dross or slag containing gas porosity. Degassing is the process of removing these gases.

The discovery of 3He in basaltic glasses and in seawater that has cycled through mid-ocean ridges has confirmed the reality of the release of juvenile gases from the mantle today. The rate of 3He loss from the mantle is now reasonably well-known. Since the ratio of the concentration of this nuclide to that of 20Ne, 36Ar, 84Kr, 132Xe has been measured ...

Previously reported experimental data show that argon injection is effective for deoxidizing steel in 10-lb induction furnace heats. Present tests, conducted in a covered ladle with argon injected either through a lance or a bottom-mounted device, indicate that it is possible on a 1-ton scale to closely approach the results of the smaller experimental ...

Plasmonic nanoheater for formaldehyde degassing
Chemical Engineering JournalFormaldehyde, a harmful indoor air pollutant with carcinogenic and irritative effects, poses significant health risks and economic burdens. However, formaldehyde is commonly utilized as an adhesive in wood and wood composites, with aldehyde-based resins frequently found in paints, flooring, and furniture.

Degassing properties of nickel
British Journal of Applied Physics, 1962The grades of nickel used in the electronic valve industry, containing magnesium, silicon and carbon among other impurities, have been found to have gas contents in the range 1.5 to 16 ml. torr g-1, the average value being about 5.0 ml. torr g-1. The total quantity of gas evolved is limited by the amount of oxygen present in the form of oxides of the ...

Overview of Ultrasonic Degassing Development
2017Ultrasonic degassing attracts industrial attention as an alternative to Ar-rotary and Ar-lancing degassing, offering environmentally friendly, economical and efficient technology. This paper gives a brief historical overview of ultrasonic degassing development in the 1960s–2010s, discusses basic principles of cavitation-induced degassing and ...

Earth’s CO2 degassing in Italy
2010Earth’s CO2 emission in Italy includes both volcanic and non-volcanic degassing, with measured CO2 fluxes of about 35 - 60 Mt/y. Zones of non-volcanic CO2 emission include Tuscany, Latium, Campania, the Apennines, Sicily, and Sardinia. Volcanic emissions are particularly abundant at Mt.
