Definitions
- the invention is based on a method for producing a material having a two-way memory effect according to the preamble of claims 1, 2 and 5.
- the invention has for its object to provide a method for producing a technically usable reversible two-way memory effect material based on Cu / Al / Ni and Cu / Al alloys, which can be used both for the production of semi-finished products in rod, Profile and sheet shape as suitable for components that can be used in practice.
- Fig. 1 the longitudinal section through an embodiment of the material as a semi-finished product is shown in rod form. 1a relates to the state after the first method step, FIG. 1 to the finished product. 1 is the component that shows the one-way memory effect (core material), 2 is a metallic coating. The final result is that the additional component 3 is formed as an edge zone (inactive zone) of the material in the form of a rod by diffusion annealing.
- core material the component that shows the one-way memory effect
- 2 is a metallic coating.
- the additional component 3 is formed as an edge zone (inactive zone) of the material in the form of a rod by diffusion annealing.
- 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 the 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 effect) component of the pressed body.
- 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.
- 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 FIGS. 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 I (Cu / Al / Ni and Cr / Ni steel).
- 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 a round rod made of 5 mm diameter Cr / Ni steel was placed coaxially in the middle. Then the free space of the capsule was 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. After the hot-isostatic pressing, the casing made of soft steel was removed by mechanical processing and the pressed body made of composite material was hammered at a temperature of 850 ° C in several steps to the desired finished size (rod shape).
- 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, into 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%.
- Round hammering produced a solid, compact composite material that had a significant two-way memory effect. It should be emphasized that only the highly elastic properties of the second, inactive component forming the edge zone were used, but not the memory effects that are also inherently present (they are not in the temperature range of interest).
- soldering, welding, roll cladding, extrusion or other metallurgical processes as well as gluing can be used as the manufacturing process for connecting the components with different physical properties.
- u. a. 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 subsequent rotary hammering.
- an additional corrosion protection layer e.g. B. 5 to 100 microns thickness applied or generated 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 can be made up of various components (including reinforcement materials). 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.
