Abstract: Apparatus for making butt-welded tube from a strip includes a pair of grooved weld rolls for aligning the longitudinal edges of the strip bent into a tubular shape. To insure that the inside seam of the tube is flush regardless of variations in thickness between strip edges, each roll is made in two sections. In a horizontal mill the seam is on top and each bottom roll section is fixed in horizontal position while the top roll section has limited axial movement. Resilient means bias the roll sections apart and against a top stop so that the top of one edge of the strip is higher than the other when the edges are of different thicknesses. If desired, the rolls may also be adjusted to insure that the outside seam of the tube is flush.

Abstract: The invention relates to a novel alloy consisting essentially of 13-18% nickel, 7-11% aluminum, 0.5 to 10% cobalt, 0.1 to 2% silicon and the remainder substantially all iron, as is produced by heating the alloy composition to a temperature of about 1650.degree. C. or above to form a melt and then casting the melt in a suitable mold. After solidification, the casting is heated to approximately 1150.degree. C., held at that temperature for a sufficient time to insure that the whole mass is heated uniformly, and then cooled at the rate of about 300.degree. C. per minute. Parts are then given an aging for the purpose of producing uniform magnetic properties throughout the casting. Magnets thus cast, heat-treated and aged as aforesaid produce very stable magnetic properties with typical values of Br = 10,000, Hc = 150 and BH max = .85.A further improvement in properties can be achieved by a second stage heat treatment wherein castings are heated to about 900.degree. C.

Abstract: A process for preparing metal having a substantially uniform dispersion of hard filler particles. The process includes the steps of: admixing metal powder and oxide particles having a negative free energy of formation at 1000.degree. C of at least as great as that of aluminum oxide; and of milling the mixture for a period of time sufficient to effect a substantially uniform dispersion of said oxide particles in said metallic powder. Milling is performed in an atmosphere containing sufficient oxygen to substantially preclude welding of particles of said metallic powder to other such particles. After milling, the dispersion strengthened powder is heat treated to remove excess oxygen therefrom.
