    摘要： Magnesium-based alloy wire excelling in strength and toughness, its method of manufacture, and springs in which the magnesium-based alloy wire is utilized are made available. The magnesium-based alloy wire contains, in mass %, 0.1 to 12.0% Al, and 0.1 to 1.0% Mn, and is provided with the following constitution. Diameter d that is 0.1 mm or more and 10.0 mm or less; length L that is 1000d or more; tensile strength that is 250 MPa or more; necking-down rate that is 15% or more; and elongation that is 6% or more. Such wire is produced by draw-forming it at a working temperature of 50° C. or more, and by heating it to a temperature of 100° C. or more and 300° C. or less after the drawing process has been performed.

    摘要： There is provided a strand that can reduce the trouble in constructing an object to which compression force is applied by the strand and that can keep the construction cost down.A strand 1 is placed in a bore hole provided in a wall or roof surface, and is gripped by a wedge in a tensioned state so as to apply a tensile force to the wall or roof surface. The strand 1 of the present invention includes a pipe-shaped member (corrugated tube 11) made of metal, and a plurality of metal wires 12 arranged on the outer periphery of the corrugated tube 11. The metal wires 12 are arranged to surround the corrugated tube 11 on the cross section of the corrugated tube 11.

    摘要： In one aspect, the present disclosure relates to a high-strength prestressing strand having a seven-wire structure in which one core wire and six outer wires are stranded. An external diameter of the strand is from 15.0 mm to 16.1 mm, a total cross-sectional area of the strand is 135 mm2 or more, and a load at 0.2% permanent elongation is 266 kN or more. A relaxation value measured after a 1000-hour relaxation test is 2.5% or lower and a diameter of the core wire is 5.35±0.3 mm and a diameter of the outer wires is 5.15±0.25 mm. The core wire and the outer wires each have a composition of at least 0.90% carbon. The prestressing strand is manufactured by stranding the core wire and outer wires, giving a stretching treatment, and giving a bluing treatment at a temperature of 380° C. or more and 430° C. or less after or at the same time with the stretching treatment.
