Electron microscopy analyses were used to unambiguously identify the crystallographic nature of the largely speculated about Mo-based and carbon-rich intergranular precipitates in a newer c¢ precipitation strengthened ...

Roads form an integral part of our lives and provide means of safe and economic transport of goods and people for various purposes. Presently, majority of our roads both in rural areas and urban centre are in a deplorable ...

This chapter reports on the learning experience in a six-week Medical Device Design course in the Division of Biomedical Engineering at the University of Cape Town (UCT). The six participants were academics from the ...

Gleeble thermomechanical simulation and microstrucutural analyses of laser beam weldability of a newly developed precipitation-hardened nickel-base HAYNES alloy 282 were performed to better understand the fundamental ...

The paper examines the solution heat treatment of an extruded 6063 aluminum alloy. The study shows that the strength and fracture resistance of this metal alloy can be influenced to an appreciable extent by the solution ...

Engineering education in Africa is faced with formidable challenges, ranging from poor funding to inadequate facilities, poor staff training, and weak linkages to the international engineering community, insufficient ICT ...

This study investigates numerically the effect of increasing heat load on thermal performance of six different heat sinks. The heat sinks examined were the single-layered microchannel, two-layered microchannel with parallel ...

In this paper, the philosophy of engineering and technology education curricula in Nigerian Universities is presented. The paper notes that in formulating the curricula, industrial training is incorporated into the programme ...

In the current study, the influence of delta (δ) ferrite on the corrosion susceptibility of AISI 304 austenitic stainless steel was evaluated in 1Molar concentration of sulphuric acid (H2SO4) and 1Molar concentration of ...

A study of the cause of heat affected zone (HAZ) cracking and its dependence on heat input during laser beam welding of a newly developed c9 precipitation strengthened nickel based superalloy Haynes 282 was performed. ...

Reliable technical methods for wax build up control in pipelines are critical to the production of crude oil in deep cold water environments. The effectiveness of groups of acrylate ester copolymers of varying alkyl side ...

The effects of 1.8-2.6% Magnesium addition on the mechanical and corrosion responses of 7249 aluminum alloy have been studied. Samples of the alloy in as-cast, T6 and RRA forms were made and subjected to tensile and hardness ...

This this paper, the influence of six curing methods (water, air, moist soil, jute bag, air/water and water/air) on the compressive strength of concrete cube specimens that contain laterite fine aggregate is investigated. ...

The mechanical and physicochemical properties of polyester reinforced with untreated palm kernel shell (PKS), sugarcane bagasse (SB), and pineapple chaffs (P) are investigated. A simple hand-lay method was used to produce ...

Utilisation of waste materials such as crumb rubber for construction purposes is still in the formative stage in Africa. Experimental evaluation is required to encourage the use of crumb rubber for concrete production. The ...

The influence of solid-state diffusion-controlled soluteloss into additive powder particles (APPs), as determined by particles size, during the equilibration stage of wide-gap brazing, on microstructure and fatigue behavior ...
