Abstract

1466342 Altering physical properties of wire, strip &c. BRUNSWICK CORP 18 Feb 1974 [21 Feb 1973] 7359/74 Headings B3A and B3V The torsional strength of metal wire, rod, strip, tube, I-section &c. is increased by a cold reduction operation combined with a twisting operation, substantially all twisting taking place within the reducing portion of a die. An anistropic two-phase metal is used in which at least 15% of the harder phase is present and the metal has a uniformly fiberized structure produced in at least one of the phases by cold working, heat treatment or controlled directional solidification which may be adapted to produce a helical fiberized structure. Suitable metals are beta titanium, beta zirconium, 18-8 stainless steel, gamma uranium, medium and high carbon steel, silver-copper alloys, silver-nickel alloys and aluminium-beryllium alloys. Two compositions of 18-8 stainless steel and one of high carbon steel are given in the Specification. In the example, wire 40 on reel 54 is drawn through a die 70 on to a take-up reel 84. The reel 54 is mounted in a yoke 52 which is rotated by a variable-speed motor 50 so that the wire is twisted in the reduction zone of the die, Fig. 2 (not shown). An adjustable clutch 62 provides back-tension, and twist is arrested by spring-pressed rolls 82. Reduction in the die may be from ¢ to 25% or 30% in one or more passes, preferably of 10-20% per pass. Twist angles range from 5 to 60 degrees. An 18-8 stainless steel may be cold worked, twist drawn and possibly further reduced by 5-10% to improve fatigue life and fracture strength. The torsioned yield strength of wires was up to 50% greater in the directional of pre-staining than in the opposite direction, and in the examples the volume of martensite exceeded 50%.
