Microstructure Control of Steels through Dispersoid Metallurgy Using Novel Grain Refining Alloys
ISIJ International, 2006 This paper describes how small inclusions (designated dispersoids) can be used to control the microstructure of steels. The term "dispersoids" refers to oxides, sulphides, nitrides and carbides which are in the 1 μm size range and capable of promoting grain refinement during solidification by a process of epitaxial nucleation or in the solid state ...

Journal of Sustainable MetallurgyAbstractCarbon-rich sources, such as coal and carbon monoxide gas, have been extensively used in the metal industry as the reducing agent of metal oxides and as the energy source for metal production. Consequently, the extractive metal sector contributes to approximately 9.5% of global greenhouse gas emissions.

Determination of RTD Curves for Aluminium Refining Process Conducted in Batch Reactor – Physical Modelling [PDF]
Archives of Metallurgy and Materials, 2018 It is really hard to determine the phenomena occurring during aluminum refining process using argon blowing through the liquid metal in industrial conditions. The solution of such problem is physical modelling. This kind of modelling gives possibility to determine the level of dispersion of the refining gas in liquid metal.

A Treatise on Electro-Metallurgy: Embracing the Application of Electrolysis to the Plating, Depositing, Smelting, and Refining of Various Metals, and to the Reproduction of Printing Surfaces and Art-work, etc [PDF]
Nature, 1911 THE work of revising the excellent treatise of the late Mr. W. G. McMillan has, on the whole, been admirably done by Mr. Cooper, although there still remain a few slight errors in the body of the work which might have been corrected. For example, it is manifestly an error to recommend for nickel deposition a solution of 8 pounds of nickel ammonium ...

Production of refining alumina-containing fluxes by sintering from technogenic raw materials
Izvestiya. Ferrous Metallurgy, 2023 Modern Russian steelmaking plants use predominantly alumina-containing materials for liquefying lime in a ladle-furnace unit, which replaced fluorspar. Alumina-containing materials currently available on the market cannot be used directly in steelmaking ...

Grain Refinement of Ti-15Mo-3Al-2.7Nb-0.2Si Alloy with the Rotation of TiB Whiskers by Powder Metallurgy and Canned Hot Extrusion [PDF]
Metals, 2020 In situ synthesized TiB whiskers (TiBw) reinforced Ti-15Mo-3Al-2.7Nb-0.2Si alloys were successfully manufactured by pre-sintering and canned hot extrusion via adding TiB2 powders. During pre-sintering, most TiB2 were reacted with Ti atoms to produce TiB. During extrusion, the continuous dynamic recrystallization (CDRX) of β grains was promoted with the

Advances in Understanding of the Application of Unit Operations in Metallurgy of Rare Earth Elements
Metals, 2021 Unit operations (UO) are mostly used in non-ferrous extractive metallurgy (NFEM) and usually separated into three categories: (1) hydrometallurgy (leaching under atmospheric and high pressure conditions, mixing of solution with gas and mechanical parts ...
