[Technical Field] The present invention relates to a Ni--Ti base alloy material with excellent superelasticity and irreversible shape memory properties (hereinafter abbreviated as shape memory properties), and a method for producing the same. [Prior art and its problems] Ni and Ti are mixed in an atomic ratio of 1:1 or close to that.
Ni-Ti alloy containing Ti and V, Cr, Mn,
Ni-Ti base alloys containing Fe, Co, Cu, Zr, Nb, Mo, Ta, or noble metals undergo martensitic transformation at a specific temperature around room temperature, resulting in superelasticity and shape memory properties. It is known to exhibit a unique phenomenon. This superelasticity is used as a high-performance spring material,
The practical use of shape memory as a temperature sensor, actuator, or an element that also serves as both is progressing, but materials with sufficient performance, such as low residual strain and long life, are required for this purpose. 〓〓〓〓〓
Metallurgically, it can be predicted that promoting stress-induced martensitic transformation while minimizing dislocation slippage is effective in improving the superelasticity and shape memory of Ni-Ti-based alloy materials. To achieve this, the Ni-Ti base alloy is cold-worked to work harden it, and then subjected to shape memory treatment at a temperature and time that does not cause recrystallization, for example at 400°C for 30 minutes. A method is proposed. In the Ni-Ti base alloy material obtained by this method, the texture formed by cold working does not disappear by shape memory treatment, so it is difficult for dislocation slip to occur and it is resistant to external stress. The stress-induced transformation proceeds without much influence. As a result, good superelasticity can be obtained above the transformation temperature, and good shape memory properties can be obtained beyond the transformation temperature. However, since such a method requires sufficient cold working, it is effective for thin wires and thin plates where processing can be easily applied to the inside, but it is effective for thick wires, thick plates, etc. Items that are not uniformly processed inside, such as bulk shapes,
If the Ni content exceeds 51.0 at%, it becomes hard and difficult to cold work due to its composition, there is a drawback that sufficient cold working is impossible and cannot be performed. [Means for solving the problems and their effects] In view of this, the present invention has been developed as a result of various studies, and has been developed by dispersing and precipitating fine Ni 3 Ti phases in the matrix of the alloy and by making the internal stress uniform. We discovered that good superelasticity and shape memory can be obtained without the need for processing, and developed a superelastic and shape memory Ni-Ti base alloy material and its manufacturing method. That is, the Ni-Ti base alloy material of the first invention of the present application is
It is characterized by having a fine Ni 3 Ti phase dispersed and precipitated in the matrix of an alloy consisting of 50.0 to 52.0 at% Ni and the balance Ti, and having uniform internal stress. Moreover, the Ni-Ti base alloy material of the second invention of the present application has Ni50.0~
V, Cr, Mn, Fe, Co, Cu, Cr, Mn, Fe, Co, Cu,
Fine Ni 3 Ti phase is dispersed and precipitated in the matrix of the alloy substituted with one or more elements selected from Zr, Nb, Mo, Ta, and noble metals, and the internal stress is uniform. It is characterized by: In addition, the Ni-Ti according to the first invention and the second invention of the present application
The method for producing the base alloy materials includes solution treatment of alloys having the above composition ranges at a temperature of 700 to 1100°C, and then
It is characterized by aging treatment at a temperature of 300 to 600°C. However, the Ni-Ti of the first invention and the second invention of the present application
The reason why the composition range of the alloy in the base alloy material is limited as described above is as follows. The reason why the Ni content in the first invention was limited to 50.0 to 52.0 at% is that if the Ni content is less than 50.0 at%, sufficient superelasticity and shape memory properties cannot be obtained, and if it exceeds 52.0 at%, the workability becomes difficult. This was determined to be of no practical value because it significantly lowers the temperature and causes cracks even during hot forging. Regarding the alloy of the second invention, 1.0 at% or less of the Ni or Ti content of the first invention alloy is replaced by V, Cr, Mn, Fe, Co, Cu, Zr, Nb, Mo, Ta.
Replacement with one or more of the noble metals is V, Cr, Mn, Fe, Co, and Cu, without significantly changing the superelasticity and shape memory properties of the alloy. It has the effect of lowering the temperature and controlling the transformation temperature to the low temperature side.
Substitution with Zr, Nb, Mo, Ta, and noble metals has the effect of improving corrosion resistance without significantly changing the superelasticity and shape memory of the alloy. This is because if the content exceeds 1 at%, not only processability is impaired, but also superelasticity and shape memory properties are deteriorated. In addition, in the first and second invention alloys, the fine Ni 3 Ti phase is dispersed and precipitated in the matrix of the alloy and the internal stress is uniform, which deteriorates superelasticity and shape memory. This is to make it difficult for dislocation slip to occur and to reduce residual strain. In addition, Ni-
In the method for producing a Ti-based alloy material, after solution-treating the Ni-Ti-based alloy at a temperature of 700 to 1100°C,
The reason why the aging treatment is carried out at a temperature of 300 to 600°C is to disperse and precipitate a fine Ni 3 Ti phase in the matrix of the alloy and to make the internal stress uniform. However, the reason why the solution treatment temperature was limited to 700 to 1100℃ is that if the treatment temperature is less than 700℃, solution treatment will not be performed sufficiently, and if it exceeds 1100℃, some parts will melt.
Or, it may cause deformation. Solution treatment involves heating to a temperature of 700 to 1100°C in an inert gas atmosphere, such as argon. Similar results can be obtained within this temperature range, and the heating time can also be reduced.
Similar results can be obtained within the range of 0.5 to 10 hours〓〓〓〓〓
It can be done. Predetermined properties can be obtained by air quenching, but water quenching is preferable in order to ensure reproducibility. In addition, the aging treatment temperature after solution treatment is 300 to 600℃.
The reason for this limitation is that at temperatures below 300°C, aging precipitation is insufficient and good properties cannot be obtained, and at temperatures above 600°C, the Ni 3 Ti single phase enters the region, making it difficult to obtain good properties. This is because there is no The processing time depends on the size of the treated material, but the processing time is 1 to 10 minutes at a temperature of 400℃.
Similar results can be obtained within the range of time, and practically good results can be obtained at a temperature of 350 to 450°C for 1 to 2 hours. [Example] Hereinafter, the present invention will be described in detail with reference to Examples. The alloy having the composition shown in Table 1 was heated to a temperature of 1000℃ and water quenched, and then aged at a temperature of 500℃ for 1 hour. The sex was measured. The results are also listed in Table 1. For reference, the superelasticity and shape memory properties after solution treatment were measured, and the results are also listed in Table 1. Each alloy is melted in a vacuum high-frequency melting furnace using a graphite crucible using a conventional method, and the ingot is cast into a water-cooled mold and subjected to hot forging and hot rolling, followed by repeated intermediate annealing and cold wire drawing. Finished with a 1.0mm line. However, since it was difficult to wire-draw the invention alloy No. 5, it was rolled to a thickness of 1 mm.
Finished to a board with a width of 3 by cutting with a whetstone.
mm, and the length was cut to 150 mm to obtain a plate-shaped sample. After removing scale on the surface of these wire rods and plate materials, they were solution-treated at a temperature of 1000℃ for 1 hour in an argon atmosphere, quenched in ice water, placed in a quartz tube, and heated at a temperature of 500℃ for 1 hour. Time-aged. Shape memory is defined by winding a wire or plate material around a 10mm diameter iron rod at a temperature 20℃ or more below the transformation temperature, removing it from the rod in that state, heating it in hot water, and forming a straight line when the temperature reaches the transformation temperature or higher. The degree of recovery is measured by angle, and if the angle is 175° or more, ◎
If the angle is 135° or more and less than 175°, mark ○, 135
Those less than ° are marked with △. In addition, for those whose transformation temperature was below room temperature, winding was performed in a mixed solution of dry ice and alcohol. In addition, superelasticity is measured by winding a wire or plate material around a 10 mm diameter iron rod at a temperature higher than the transformation temperature, removing the winding force, and measuring the angle after recovery due to spring back. It was shown as follows.
