Abstract A summary of the history of electric ironmaking furnaces, including open-bath types, electric shaft furnaces, and low-shaft electric furnaces, this article also describes industrial installations. Economic comparisons are made between blast furnaces and electric-furnace practices using ore, agglomerates, and preheated and prereduced charging materials.

Abstract Liquid metals and their properties, as applied to space electric-power systems, are discussed as possible heat-transfer and thermodynamic working fluids. Representative liquid metals—lithium, sodium, potassium, NaK-78, lead, and bismuth — tare discussed and compared. Space power requirements are listed and used as a basis for evaluating the potentialities of the liquid metals.

Abstract The potential of vanadium alloys for applications above 2000°F is described. Mechanical properties are tabulated and reviewed, with major emphasis on the vanadium-columbium alloys. Evaluations of fabricability are considered, and investigations of several oxidation-protection systems, particularly pack-siliconizing treatment, are detailed.

Abstract The present and future uses of the superalloys in aerospace are outlined. The properties of super-alloys in the 1000° to 1900°F range are listed, including fabrication methods and oxidation protection. Compositions of various superalloys are tabulated, and oxidation-resistance coatings are illustrated.

Abstract A procedure developed by the US Bureau of Mines to recover rhenium in the form of electrolytic flakes by electrowinning the metal from a solvent-extraction strip solution is described. The recovered rhenium contains only about 0.1 % Mo and spectrograph traces of other impurities, such as copper, aluminum, calcium, chromium, iron, platinum, and silicon. The uses and properties of rhenium are discussed, and conventional recovery methods are reviewed.

Abstract The overall conditions which are necessary for rapid and economical steelmaking are reviewed. The advantages and disadvantages of the LD, Kaldo, Rotor, and open-hearth practice with and without oxygen utilization are discussed. A method of continuous steelmaking is described, and the advantages of such a process are discussed in detail.
