The impact of forensic laser scanning technology on incident investigations in the mining industry (Southern African Institute of Mining and Metallurgy, 2019-10)Risk assessments have been conducted in the South African mining industry over the past 20 years, but still we do not always correctly identify the root cause of an incident. An incident investigation is not only about ...
-
(Southern African Institute of Mining and Metallurgy, 2019-10)The mining industry of the 21st century needs a new kind of leader as certain leadership styles and most leadership models currently employed in the world, and also in South Africa, are not sustainable. This article ...
-
(IOP Publishing, 2019-11-09)Electron backscattered diffraction (EBSD) has been conducted to determine the orientation relationship of the remnant B2 phase in an -solidified -Ti-45Al-2Nb-0.3Si (at. %) based intermetallic alloy. The morphology and ...
-
(IOP Publishing, 2019-11-09)The present study focused on preparation and characterization of 60Al-40V master alloy which was produced via aluminothermic process. The study assessed the production in order to provide the optimum Al requirement for ...
-
(IOP Publishing, 2019-11-09)The influence of the individual equiaxed and columnar cast structure on the evolution of texture during thermo-mechanical processes (TMP) was investigated using the electron backscatter diffraction (EBSD) technique. The ...
-
(IOP Publishing, 2019-09-09)In South Africa, forged wheels for rail cars are imported but cast wheels are manufactured locally, although recent developments indicate that forged wheels will in future be manufactured locally. The forged wheels are ...
-
(IOP Publishing, 2019-09-09)A homogeneous microstructure is required for consistent mechanical properties in normalised Nb-Ti-V microalloyed plate steels. Frequently, as-hot rolled microalloyed plate steels have a banded microstructure that is ...
-
(IOP Publishing, 2019-11-09)Metallic biomedical implants such as titanium-based alloys are very useful for orthopaedic applications due to their excellent properties which responds to changes in temperature and other conditions. However, biological ...
-
(IOP Publishing, 2019)The strain hardening behaviour of AISI 301 metastable austenite steel was analysed by evaluating tensile data against the empirical mathematical equations of Hollomon, Ludwik and Ludwigson. It was found that these equations ...
-
(IOP Publishing, 2019-11-09)Vanadium produces the hardest carbides and can influence wear properties positively. However, due to the minerals’ price fluctuations as a result of the current economic climate, vanadium is currently expensive and ...
-
(IOP Publishing, 2019-11-09)A steel of composition Fe-0.2C-3Mn-2Si-0.5Al was fully austenized followed by a quench and partitioning heat treatment process (Q&P). The quench temperature was varied, which resulted in different volume fractions of ...
-
(Springer, 2020-01)A simple mathematical model has been developed which describes the flow curve behavior up to the peak true stress or a true strain of 0.6 in unstable austenite. The hot working behavior was analyzed by compression tests ...
-
(Universidade Federal do Rio de Janeiro, 2019)The use of copper slag as a partial substitute for cement in mortar preparation was studied. Copper slag samples were collected from three dumps in the Atacama Region (Northern Chile). Mortars of 40x40x160 mm (width, ...
-
(Elsevier, 2019-06)Please read abstract in the article.
-
(Springer, 2019-08)Ti-6Al-4V produced by laser powder bed fusion can achieve mechanical properties similar to its wrought counterpart if an appropriate post-process heat treatment is applied. The response of the material to post-process heat ...
-
(Elsevier, 2019-08)Bonded repairs using composite patches over metallic structures have been evaluated as a cost effective method to increase the life of damaged structures. The J-integral is a widely applied fracture mechanics parameter ...
-
(Mary Ann Liebert, 2019-10)This article reports on an exceptional insight provided by nondestructive X-ray tomography of the same samples before and after laser shock peening (LSP). The porosity in two additively manufactured aluminum alloy (AlSi10Mg) ...
-
(Southern African Institute of Mining and Metallurgy, 2018-10)This work presents the potential for improving the flotation recovery of slow-floating sulphide minerals with the use of starvation dosages of a normal dodecyl (n-C12) trithiocarbonate (TTC) co-collector, together with a ...
-
(Southern African Institute of Mining and Metallurgy, 2018-12)Although oxygen is widely employed as the oxidant of choice in gold leaching by cyanide, its low aqueous solubility presents some drawbacks in practical application; hydrogen peroxide has therefore been considered as a ...
-
(Elsevier, 2019-12)Beta (β) solidifying γ-TiAl intermetallic alloys of nominal composition Ti-48Al, Ti-48Al-2Nb, Ti-48Al-2Nb-0.7Cr alloys have been cold pressed and vacuum arc melted. The Al loss was due to compaction method used prior to ...
