Industry Practice

Alloy scrap metal is increasingly being used in electric arc furnace (EAF) steelmaking and the alloying elements are also found in the resulting dust. A comprehensive characterization program of EAF dust has been undertaken in collaboration with the steel industry and AISI. Samples have been collected from the furnaces of 28 steel companies representing the broad spectrum of industry practice. The program aims to develop an understanding of the mechanisms of formation so that procedures to recover residual elements or recycle the dust can be established. The multi-phase, multi-component dust particles are amenable to individual particle analysis using modern analytical electron microscopy (AEM) methods.Particles are ultrasonically dispersed and subsequently supported on carbon coated formvar films on berylium grids for microscopy. The specimens require careful treatment to prevent agglomeration during preparation which occurs as a result of the combined effects of the fine particle size and particle magnetism. A number of approaches to inhibit agglomeration are currently being evaluated including dispersal in easily sublimable organic solids and size fractioning by centrifugation.

High Magnetic Permeability

Abstract HP magnet steel is designed for use wherever high magnetic permeability or high saturation values are required. Its magnetic qualities result from careful control of sulfur and residual elements plus the special deoxidization practice, which minimizes nonmetallic inclusions. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: CS-144.

Effect Of Copper

Because of the increase in the levels of residual elements in steel, a programme of work was initiated to determine the limits of copper and tin impurities that were tolerable in steel castings. A 1.5 % Mn—Mo steel was chosen as a base, since any effect of trace elements would be readily apparent in terms of mechanical performance in this medium—high strength steel. The effect of copper was investigated within the range < 0.01-0.5 %, and tin within the range < 0.01-0.26%. The results were analysed by using factorial analysis in the first instance and later, as the amount of experimental work expanded and more results became available, a regression analysis was used.

This article reflects upon themes and foundations of the contemporary legalism attending the resolution of aboriginal claims. It opens with a broad description of the historical foundation of that legalism in the imperial prerogative of the Crown and its continuance in the national constitutional systems of Canada and New Zealand. It then considers how that legalism, with its origination in the imperial prerogative and the ongoing comparative dimension associated with that origin, inhabits a recent local example, namely New Zealand’s Marine and Coastal Area (Takutai Moana) Act 2011. The article shows how this provision reflects the general features of indigenous rights' jurisprudence as it has emerged over the past 30 years: it carries residual elements of the imperial prerogative and it has a comparative element, yet it is also a peculiarly New Zealand instance that marks a new step in the jurisprudence.
