(Southern African Institute of Mining and Metallurgy, 2017-10)The current study is intended to characterise the complex microstructure that results from autogenous welding of Zr-2.5Nb and its influence on mechanical properties. Laser beam welding (LBW) and gas tungsten arc welding ...
-
(Elsevier, 2018-10)Structure-property relationship of the as-cast γ-Ti-45Al-2Nb-0.7Cr-0.3Si based intermetallic alloy was examined. The phases stable at room temperature in the alloy were γ/α2/Ti5Si3, respectively; while their crystal ...
-
(Iron and Steel Institute of Japan, 2018-02-15)Please read abstract in the article.
-
(Southern African Institute of Mining and Metallurgy, 2017-07)Extraction of nickel from either laterite or sulphide ores involves various complex hydrometallurgical processes, the final step of which is often electrowinning to produce pure nickel metal. Methods to investigate, monitor, ...
-
(Elsevier, 2018-08)The γ-TiAl intermetallic alloy doped with Nb, Cr, and Si metals has been developed. It has emerged that the ternary Ti-48Al-2Nb and quinary Ti-48Al-2Nb-0.7Cr-0.3Si alloys yielded the best mechanical and cyclic oxidation ...
-
(Elsevier, 2018-08)The γ-Ti-45Al-2Nb-0.7Cr-0.3Si based intermetallic alloy was developed. Microstructure evolution of the as-cast and heat-treated alloy yielded the spheriodised and Widmanstätten laths. High temperature differential thermal ...
-
(Taylor and Francis, 2018)Kimberlite is the host rock of diamonds and varies widely in geological and mineralogical features as well as color, processing capability, and dewatering characteristics. This study investigated the dewatering behavior ...
-
(Taylor and Francis, 2018)This study focus on the upgrading of SLon concentrates, of a complex African iron ore, with the aid of flotation. Mineralogical studies indicated that the +38µm material was not liberated and required milling prior to ...
-
(Taylor and Francis, 2018-04)The SAF (submerged arc furnace) process is most widely used for industrial production of high carbon ferromanganese. Most plants use ore feed in the form of lump ore (−75 mm +6 mm), but long term supply is limited, and ...
-
The effect of processing parameters on ferromanganese alloy carbon content in Mamatwan ore reduction (Taylor and Francis, 2017-01)Industrial production of medium carbon ferromanganese is accomplished by decarburization of high carbon ferromanganese in an oxygen blown converter. In this study, the possible in situ refinement of high carbon ferromanganese ...
-
(Springer, 2017-11)This work extends the application of the well-established Estrin and Mecking (EM) work-hardening model in unstable low temperature austenite region. The interaction between work hardening, recovery and softening attributed ...
-
(Mineralogical Society of America, 2017-10)The sustainability of a mineral resource depends, among other aspects, on what the mineral in question will be used for, price fluctuations, future resource requirements, and downstream manufacturing. A balance must be ...
-
(Iron and Steel Institute of Japan, 2017)The roughing conditions required to avoid local heterogeneous regions in the final microstructure of high temperature processing (HTP) Nb linepipe steels have been investigated for quasi-compact strip production (CSP) ...
-
(Springer, 2017-11)Please read abstract in the article.
-
Influence of a carboxymethyl cellulose (CMC) binder on the mechanical properties of iron ore pellets (Southern African Institute of Mining and Metallurgy, 2017-04)Carboxymethyl cellulose is an organic binder used in the iron ore pelletizing industry. The basic principles of how carboxymethyl cellulose (CMC) solutions behave during the pelletizing process and how these principles ...
-
(American Nuclear Society, 2013-04)The crushing strength (load at fracture) of coated particles was measured by compression between soft metal anvils. The method requires no sample preparation and can be used as a quality control method as well as a valuable ...
-
(Springer, 2017-06)Plain carbon steels that are in service at elevated temperatures (typically 400-450 °C) for prolonged periods of time (typically in excess of 20 years) may experience graphitization, often in the heat affected zone (HAZ). ...
-
(Springer, 2016-02)Crystals of a silico-ferrite of calcium and aluminium (SFCA) and an Al-free SFC were prepared from the melt by slow cooling of synthetically prepared mixtures and examined by single-crystal diffraction methods. Both ...
-
(Elsevier, 2016-06)The Holland-Batt spline is well known when it comes to plotting spiral separation performance. The spline, which consists of a linear curve and power curve, has been successfully used to fit test work data that is presented ...
-
(Elsevier Science Limited, 2016-12)A major obstacle to the hydrometallurgical treatment of ferromanganese slags is the way in which silica polymerisation is controlled during sulphuric acid digestion and water leaching. In an acidic medium, silica enters ...
