-
(Springer, 2021-09)Selective laser melting is one of the additive manufacturing technologies that have been known for building various and complicated shapes. Despite numerous advantages of additive manufacturing technologies, they strongly ...
-
(Southern African Institute of Mining and Metallurgy, 2020-06)Denel Dynamics, a South African armaments development and manufacturing company, is interested in introducing additive manufacturing (AM) in the fabrication of missile components. The practicality of using AM for industrial ...
-
(Southern African Institute of Mining and Metallurgy, 2020-06)Sulphur driven off from the sulphides in the black top of PGM smelters has in past years caused failure of copper coolers. When the magnesia-chromite bricks in the smelter were replaced with graphite blocks, however, ...
-
(Elsevier, 2020-09)Please read abstract in the article.
-
(Springer, 2020-10)A series of fused CaF2-SiO2-CaO-based fluxes geared towards submerged arc welding has been prepared with incremental TiO2 additions. Through systematic investigation on physical properties, quantitative relationship between ...
-
(University of Pretoria, 2020)Among many shape memory alloys, Ti-Pt alloys have potential as a high temperature shape memory alloy. The alloy undergoes a reversible martensitic transformation at temperatures above 1000 oC. However, the alloy’s negligible ...
-
(University of Pretoria, 2020)Surface transverse cracking is still one of the main problems in the continuous casting of steel. The cooling rate at the corners of the slab and strand is usually the highest. Therefore, depending on the cooling regime, ...
-
Investigating the Effect of Adding a Disc Liner to the Mill Shell of a Vertical Stirred Media Mill (University of Pretoria, 2020)Comminution processes are used in the metallurgical industry to reduce the particle size of mined ores in order to liberate valuable minerals for downstream separation and extraction. Comminution is a very energy intensive ...
-
(Elsevier, 2021-01)A comparative testwork programme was conducted using a laboratory scale vertical fluidised stirred media mill. The mill was operated with and without the presence of a disc liner on the shell. Results showed that when the ...
-
(Taylor and Francis, 2022)Please read abstract in the article.
-
(University of Pretoria, 2019)Ferritic stainless steel is typically used in the automotive industry to fabricate welded tube that is plastically deformed for flanging, bending and necking. The effect of welding parameters during autogenous gastungsten arc ...
-
(University of Pretoria, 2019)Laser-powder bed fusion (L-PBF) processing finds its application in various metal forming industries such as aerospace, automotive and medical industries. Ti6Al4V alloy is widely used in aerospace applications. The main ...
-
(University of Pretoria, 2020)The focus of the current study was to investigate dephosphorization of ferromanganese to produce a low P containing alloy that could effectively be used for the production of AHSS. The study involved conducting laboratory ...
-
The development of a risk-based model to predict corrosion fatigue failures in subcritical boilers (University of Pretoria, 2020)The increased energy demand within South Africa has led to continued periods of load shedding. This has had an adverse impact on industry, quality of life and the economy as a whole. A larger requirement for production ...
-
(Springer, 2020-07)The properties of steel parts after carburizing in low-pressure acetylene are studied. The thickness of the carburized layer, its hardness, the microstructure, and the hardness of the core are determined after carburizing ...
-
(University of Pretoria, 2021)This report investigates the cause of the reduction in workability and increased ageing of a blast furnace taphole clay. The taphole clay contains 60 mass% alumina, with a phenol-formaldehyde resole resin (PFR) and liquid ...
-
(University of Pretoria, 2020)Preg-robbing gold ores reduce the gold recovered with conventional aqueous cyanide processing by adsorption of the leached gold onto the ore which is then lost to the residue. Many ore constituents adsorb gold in the ...
-
(Southern African Institute of Mining and Metallurgy, 2019-03)Coal fines produced during processing are difficult to dewater and result in a lower quality product and consequent lower value. A South African coal mine experiences severe difficulties with belt filter dewatering ...
-
(University of Pretoria, 2021)The use of magnetite as a medium in the wet processing of coal has been used since the early days of dense medium separation. The high magnetic susceptibility and density of magnetite make it an ideal medium to use in wet ...
