Effect of process control agent (PCA) on the characteristics of mechanically alloyed Ti-Mg powders [Journal article]

Author: Machio, Christopher N ; Chikwanda, HK ; Chikosha, S Date: Mar 2011 This paper reports the results of a study to determine the effect of process control agent (PCA) on the characteristics of Ti-Mg powders during milling. It has been shown that a 2% increase in PCA content leads to up to a 40% increase in yield ... Read more
Magnesium: origin and role in calcium-treated inclusions

Author: Pistorius, PC ; Presoly, P ; Tshilombo, G Date: Aug 2009 Steel was sampled after calcium treatment at an industrial steel plant, and the inclusions identified by energy-dispersive X-ray microanalysis (EDX) on polished sections of the samples analysing the samples in a scanning electron microscope. ...

Magnesium: Origin and role in calcium-treated inclusions

Author: Pistorius, CP ; Presoly, P ; Tshilombo, KG Date: Aug 2006 Calcium treatment of alumina inclusions, to convert the alumina to molten or partially molten calcium aluminates, is a well-established treatment for steel, to improve the castability of aluminium-killed steel. However, the role of magnesium ... Read more
Mechanical alloying and sitering of TI - 10WT.% MG powders

Author: Machio, Christopher N ; Nyabadza, D ; Chikwanda, HK ; Phasha, M ; Sibanda, VM Date: Jun 2009 A Ti-10wt.%Mg powder alloy has been produced by mechanical alloying. Elemental powders of Ti and Mg were ball milled in a Zoz-Simoloyer CM01 for 16 and 20 hours under argon. Mechanical alloying was followed by XRD, SEM and particle size ... Read more
Proposed aesthetic/physical and inorganic drinking-water criteria for the Republic of South Africa

Author: Kempster, PL ; Smith, R Date: 1985 Using existing criteria from other countries, in conjunction with data on element toxicities and normal dietary intakes, drinking-water criteria for 56 aesthetic/physical and inorganic chemical determinants were proposed for South Africa. Read more
Semi-solid casting of pure magnesium

Author: Curle, Ulyate A ; Wilkins, Jeremias D Date: Jan 2019 Semi-solid processing works on the principal of a solidification temperature interval of a substance. The substance is heated to a temperature within this interval so that there exists a related solid-liquid fraction ratio. The substance with ... Read more
Ti-Mg alloy powder synthesis via mechanochemical reduction of TiO2 by elemental magnesium

Author: Mushove, T ; Chikwanda, HK ; Machio, Christopher N ; Ndlovu, S Date: Apr 2009 This paper reports the preliminary results of an investigation on the synthesis of a Ti-Mg alloy powder through mechanochemical processing of TiO2 and Mg powders. TiO2 was mixed with elemental Mg according to a nominal stoichiometric composition ... Read more
