    摘要: Improved technology for the melting and casting of a particular class of true beta-type titanium alloys is described. A typical alloy is titanium--35% vanadium--15% chromium. By providing carbon surfaces for contacting molten beta titanium alloys of this type improved melting and casting procedures are effectuated.

    摘要: A composition for the preparation of articles of calcium oxide, comprising calcined calcium oxide and an organic phase consisting of at least one polyol in an anhydrous medium. The composition may be used to form linings for molds and crucibles intended to come into contact with molten metals of groups IV and V of the periodic table.
