Definitions

  • the invention relates to a material according to the preamble of claim 1 and a method according to the preamble of claim 5.
  • the invention has for its object to provide a new material based on Cu / Al / Ni and Cu / Al alloys and a corresponding method for its production, which has a considerable reversible two-way memory effect and is both for the production of semi-finished products in the form of bars, profiles and sheets, as well as components that can be used in practice.
  • Fig. 1 the longitudinal section through an embodiment of the material as a semi-finished product in bar form is shown.
  • Fig. La refers to the state after the first process step, Fig. Lb to the finished product.
  • 1 is the component showing the one-way memory effect (core material)
  • 2 is a metallic coating.
  • diffusion annealing creates the further component 3 as an edge zone (inactive zone) of the material in the form of a rod.
  • Fig. 2 shows the process flow and the means in the manufacture of the material in rod or strip form as a tri-metal.
  • 4 is the press cylinder of an extrusion press, 5 the corresponding press plunger (punch), 6 the die.
  • the latter advantageously has a relatively narrow tightening angle (corresponding to a cone angle in the case of round cross sections) in the tapered part.
  • 7 are the outer layers of a component of the compact which shows the one-way memory effect.
  • 8 represents the inner layer of the further (no memory 9) are the outer layers of the component of the finished material showing the one-way memory effect in cross-section (flat bar).
  • 10 is the inner layer consisting of the further (inactive) component of the finished material in cross section.
  • a powder-metallurgically produced alloy of the following composition belonging to the ⁇ -brass type was selected:
  • the memory alloy was transferred to a band 2.5 mm thick by hot rolling. Then a test rod with a square cross section 2.5 x 2.5 mm and a length of 35 mm was cut out of this tape.
  • This component corresponding to 1, which shows the one-way effect (core material) was provided on two opposite sides (preferably rolling sides) with a metallic coating 2 - in the present case nickel.
  • the nickel plating was carried out according to the electroless chemical method by immersing in a bath heated to 80 ° C. for 6 hours. The bath had the trade name "Electroless Nickel" (manufacturer: Oxy Metal Industries Congress SA, Avenches).
  • the coated rod was then subjected to an annealing treatment at a temperature of 900 ° C. for 30 minutes and quenched in water.
  • the nickel diffused into the Cu / Al / Ni core material and formed the edge zone representing the further component 3 (inactive zone). This measure changed the metallurgical composition of the latter compared to the core and thus also the physical properties.
  • the edge zone lost the properties of the classic memory alloy or, if it still existed, it was not used, at least in the temperature range of interest. What remained, however, was the highly elastic behavior of the edge zone. Well-known reversible two-way memory effects could be achieved with this material.
  • Example II The same alloy as in Example I was used as the starting material for the component showing the one-way effect.
  • Prismatic bodies were cut out of this material and assembled with a flat rod made of corrosion-resistant steel (18 Cr / 8 Ni) in such a way that a laminated body (sandwich) according to 7 and 8 of FIG. 2 was formed.
  • This pressing body of rectangular cross section was inserted into an extrusion press and pressed at a temperature of 800 ° C. to form a composite material in the form of a flat bar.
  • This type of tri-metal can be produced in practically any cross-section and commercially available lengths. A well-known two-way memory effect was measured on him.
  • the starting materials for the two components had the same alloy composition as in Example II (Cu / Al / Ni and Cr / Ni steel).
  • a round rod made of Cr / Ni steel was coaxially placed in the middle of a capsule made of soft, low-carbon steel (St 35) with a height of 200 mm, an outer diameter of 80 mm and a wall thickness of 2 mm of 5 mm in diameter.
  • the free space of the capsule was then filled with Cu / Al / Ni powder and the capsule was evacuated, welded and hot-isostatically pressed at 950 ° C. for 3 hours under a pressure of 140 MPa.
  • the casing made of soft steel was removed by mechanical processing and the pressed body made of composite material was hammered in several steps to the desired finished size (rod shape) at a temperature of 850 ° C.
  • the following alloy was selected as the starting material for a composite material for the first component (one-way memory effect):
  • a sintered round rod of 20 mm diameter was first produced from the first component using powder metallurgical methods by pre-compressing and sintering the powder mixture.
  • a tube with an inner diameter of 20 mm and a wall thickness of 2 mm was made from the Ti / Ni / Cu / Fe alloy manufactured, in which the round bar just fit. The latter was inserted into the pipe in such a way that it was just stuck.
  • the composite material prepared in this way was then heated to a temperature of 850 ° C. and, at this temperature, reduced to a diameter of 10 mm in several passes by rotary hammering.
  • the cross-sectional decrease per stitch was approx. 20%.
  • the round hammering produced a solid, compact composite material that had a significant two-way memory effect.
  • the second, inactive component forming the edge zone only exploited its highly elastic properties, but not its memory effects, which are also inherently present (they are not in the temperature range of interest).
  • the material is basically made up of several layers (at least two), with at least one component showing a one-way memory effect and at least one further component which inhibits the one-way effect of the former by internal tension. This condition can already be in the normal state, but must be fulfilled at the latest in the operating state, ie taking temperature and external loads into account.
  • the material can be in the form of a bar, wire, tube, profile, sheet or strip in the form of a semi-finished product, so that it can be further processed into individual components at least when cold.
  • All materials exhibiting this property come as the starting material for the first component which shows the one-way memory effect.
  • Another way of building materials consists in the fact that the layers, based on the first (active) and the second (inactive) components, essentially belong to the same type of alloy (eg Cu / Al / Ni), whereby the transitions can be fluid.
  • their compositions must differ chemically and their physical properties, particularly with regard to memory effects, must also be qualitatively different.
  • soldering, welding, roll cladding, extrusion or other metallurgical processes and gluing can be used as the manufacturing process for connecting the components with different physical properties.
  • two-layer (bimetal) or three-layer (trimetal) materials can be produced.
  • the material can be produced from the individual components using powder metallurgy and further processed into semi-finished bimetallic or trimetal products. This can be done by cold compression, sintering and extrusion, or by hot isostatic pressing with possibly round hammers.
  • an additional corrosion protection layer of, for example, 5 to 100 .mu.m thick can be applied or produced in the edge zone. The latter of course also applies to all other manufacturing processes.
  • the composite material does not necessarily have to consist only of metallic components.
  • the inactive second component can be a high-strength, highly elastic, heat-resistant plastic, which in turn is made of various components (including reinforcement materials) can be constructed. The condition is that the plastic can withstand the elastic movements without damage and tolerates the temperatures that occur during operation.
  • the new material and the corresponding manufacturing process give the person skilled in the art a means of considerably expanding the area of application of the two-way memory effect, in particular in the temperature range between approximately 100 ° C. and 200 ° C. This applies above all to the construction of switches, relays and temperature triggers.
