-
(MDPI, 2021-02-03)This study presents the investigation on how heat treatment parameters, which are temperature, cooling method, and residence time, influence the microstructural and hardness properties of Ti6Al4V components produced on ...
-
Effect of solution aggressiveness on the crack growth resistance and cracking mechanism of AA2024-T3 (NACE International, 2021-09)Aluminum alloy 2024-T3 was examined using a range of microscopy techniques at the early stages of corrosion attack to investigate the corrosion-induced cracking mechanism. Two different corrosive environments—exfoliation ...
-
(MDPI, 2021-10-15)Improving the strength of grey cast iron wheel hubs will improve the safety of automobiles and have a great significance for energy saving and environmental protection. This paper systematically compares the calculation ...
-
(Southern African Institute of Mining and Metallurgy, 2021-09)Advanced high-strength steels (AHSS) are sophisticated materials being developed by the steel industry to mitigate challenges related to the performance of motor vehicles. To meet the requirements of AHSS, the ferromanganese ...
-
(Southern African Institute of Mining and Metallurgy, 2021-04)The study investigates the effect of prior corrosive exposure on crack growth resistance behaviour of thin sheet (3 mm thick) aluminium alloy 2024-T3 at slow strain rates. Compact tension specimens were exposed to standard ...
-
(Southern African Institute of Mining and Metallurgy, 2021-02)Accretions often form in furnaces when slag and charge materials attach to the refractory wall and build up over time. Accretion formation is usually unwanted because it reduces the working volume of the reactor and ...
-
(Southern African Institute of Mining and Metallurgy, 2021-04)Additive manufacturing can be used to produce complex and custom geometries, consolidating different parts into one, which in turn reduces the required number of assemblies and allows distributed manufacturing with short ...
-
(Southern African Institute of Mining and Metallurgy, 2021-04)The b-solidifying g-TiAl intermetallic alloys of nominal composition Ti-48Al (binary alloy), Ti-48Al-2Nb (ternary alloy), Ti-48Al-2Nb-0.7Cr (quaternary alloy), and Ti-48Al-2Nb-0.7Cr-0.3Si (quinary alloy) (in at.%) were ...
-
(Southern African Institute of Mining and Metallurgy, 2021-07)Wire-arc additive manufacturing (WAAM) is a directed-energy deposition technology that uses arc welding procedures to produce computer-aided designed parts, such as three-dimensional printed metal components. A challenge ...
-
(Elsevier, 2021-03)Post-weld slag and weld metal analyses were used to interpret the effects of different commercial flux compositions on element transfer between molten flux (slag) and weld metal in Submerged Arc Welding (SAW). Selected ...
-
(Universidad Nacional de Colombia, 2021-04)Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along ...
-
(Elsevier, 2021)Titanium aluminides are considered the choice material for next generation propulsion systems due to their high specific strength and high temperature performance coupled with good oxidation resistance. They are considered ...
-
(University of Pretoria, 2021)A low-cost titanium production process, the CSIR-Ti powder process, which aims to produce titanium powder directly by metallothermic reduction of titanium tetrachloride with lithium, has been under development at the ...
-
(Elsevier, 2021-01)A fifty litre seamless gas cylinder manufactured from a 34CrMo4 low carbon alloy steel which was in service for five years failed in an unexpected manner, causing severe damage. The cylinder was filled with a mixture of ...
-
(Elsevier, 2021-09)Please read abstract in the article.
-
(Springer, 2022-02)Ever-leaner compositions are targeted for nominal type 16–8-2 weld metals in attempts to limit sigma-phase formation during elevated temperature operation. Three variants of type 16–8-2 weld metals were exposed to aging ...
-
(Springer, 2021-08)Please read abstract in the article.
-
(MDPI, 2020-03)Please read abstract in the article.
-
(University of Pretoria, 2021)Additive manufacturing can be used to produce complex, custom geometries, consolidating different parts into one. This reduces the required number of assemblies and allows distributed manufacturing with short lead times. ...
-
(Springer, 2021-07)Alloy development opens the way to create new materials for specialized processes, and attain materials that are usually difficult to acquire. Property enhancements and part performance is achievable in an exciting new way ...
