The present invention relates to a cable using cold-drawn shape memory alloy wires, which facilitates concrete prestressing or other operations, and has excellent adhesion to concrete and manufacturability. The cable using cold-drawn shape memory alloy wires includes: a core wire configured by a cold-drawn shape memory alloy deformed by cold drawing to have an increased length; and a plurality of peripheral wires configured by cold-drawn shape memory alloy wires which are deformed by cold drawing to have an increased length and are couple to the core wire while being wound in a same direction along the circumference of the core wire.

A plurality of wire elements for use in an energy recovery device comprising Shape Memory Alloy or other Negative Thermal Expansion (NTE) material, wherein at least one wire element is fixed at one end and free to move at a second end, such that the wire elements are arranged adjacently and are in friction or interference contact with each other and are secured at the outer perimeter of wires utilising a securing means. In such arrangement, during the operation of the bundle arrangement in a heat engine system, the plate elements act to transmit the aggregated force generation of the wire grouping and thus usefully recover and transmit power.

Ultra-High-Strength (UHS) wires are suited to high strength wire, strands, cables and rope applications including robotics force transmission and other high-performance mono- and multifilament wire applications. The wires exhibit high strength, low stretch and fatigue durability. Exemplary UHS materials include binary molybdenum-rhenium or tungsten-rhenium alloys with between 20 and 50 wt. % rhenium. These alloys are processed from a moderate strength (<2 GPa) warm-drawn rod to drawn monofilament wire with extreme nanocrystalline grain refinement, high apparent fatigue durability, and ultimate strength levels exceeding 5 GPa in all cases, and up to 6.8 GPa at monofilament diameters ranging from 7 to 100 μm.

A wire cable construct including a plurality of strands each made of a plurality of wire filaments, the strands and wire filaments arranged in a 37×7 configuration of 37 strands of 7 wire filaments each, with the strands arranged in four layers including a first, central layer of a single strand, a second layer of six strands, a third layer of twelve strands and a fourth, outermost layer of eighteen strands. The cable may have a small diameter for use in medical device applications, and the strand and wire element configuration allows the cable to carry high axial loads, minimizes bending stress when the cable is routed around a tight turn such as a small pulley, and minimizes torsion in the cable due to axial loading.

A threadlike metallic or metallized reinforcer, for example a thread, film, tape or cord made of carbon steel, at the periphery of which is positioned a layer of metal referred to as surface metal chosen from copper, nickel and copper/nickel alloys, is characterized in that this surface metal layer is itself coated, at least in part, with at least one layer of graphene; preferably, there is grafted, to this graphene, at least one functional group which can crosslink to a polymer matrix. This reinforcer of the invention is effectively protected from corrosion by virtue of the graphene present at the surface; advantageously, it can be adhesively bonded directly, without adhesion primer or addition of metal salt, to an unsaturated rubber matrix, such as natural rubber, by virtue of the possible functionalization of this graphene.
