  • Method of obtaining uranium from oxide using a chloride process
    Patent number: 5164050
    Abstract: A method of obtaining uranium metal from an oxidized uranium compound, characterized in that the oxidized compound is treated with chlorine and carbon at a first stage, to obtain a chloride which is reduced by electrolysis or metallothermy using a reducing metal at a second stage.

  • Process for producing dense machinable alloys from particulate scrap
    Patent number: 4077108
    Abstract: The invention relates to a process for obtaining steels having improved machinability. This process provides for the upgrading of divided metallurgical products, which are consolidated without fusion, with incorporation of a dispersed phase.This process is used in particular for scrap consisting of sheet metal or turnings, which is mixed in the desired proportion with an additive such as for example sulfur or lead. After it has been compressed the mixture is extruded in a press in the form of bars and the like.This process is particularly suitable for producing stainless steels containing sulfur or lead. The lead stainless steels thus prepared have an excellent corrosion resistance, in addition to their machinability characteristics.

  • Free machining steel
    Patent number: 4004922
    Abstract: Free machining low alloy steel compositions are prepared by addition of very small quantities of at least magnesium to previously deoxidized steel to provide a homogeneous distribution of globular sulfides and sulfurous inclusions of the additive.
