Abstract
The invention discloses a method for controlling the phase transition temperature of a TiNiV memory alloy by cold deformation, belonging to the technical field of shape memory alloys. The method is characterized in that the TiNiV memory alloy is subjected to cold deformation treatment to form a sheet or wire, wherein cold deformation degrees are 5 percent, 10 percent, 15 percent, 25 percent and 40 percent respectively; and the cold deformation treatment is realized by two modes: first mode: the TiNiV memory alloy is pressed to form a sheet; and second mode: the TiNiV memory alloy is subjected to cold drawing to form the wire; and the sizes of two specifications can be determined according to the requirement of the engineering.
Description
Technical field
The invention belongs to the shape memory alloy technical field, refer in particular to a kind of method through cold deformation control TiNiV memorial alloy phase transition temperature.
Background technology
As everyone knows; The TiNiV memorial alloy will pass through cold deformation in process of production and handle; Such as cold rolling, cold drawn processing be configured as sheet material or the silk material just can use; Yet after the TiNiV memorial alloy process cold deformation process, can remarkable influence be arranged, that is to say that the transformation temperature that the TiNiV memorial alloy is handled the back alloy through cold deformation can raise the transformation temperature of TiNiV memorial alloy; This just causes TiNiV memorial alloy transformation temperature in application process unstable, and the relation of therefore finding out cold deformation amount and transformation temperature is most important.
The present invention is directed to this problem, develop a kind of method through cold deformation control TiNiV memorial alloy phase transition temperature.Through inquiry, not seeing has related patent U.S. Patent No. to deliver.
Summary of the invention
The present invention relates to a kind of method through cold deformation control TiNiV memorial alloy phase transition temperature.It is characterized in that: the TiNiV memorial alloy is carried out cold deformation be treated to sheet material or silk material, the cold deformation amount is respectively 5%, 10%, and 15%, 25%, 40%.Cold deformation is treated to, and the one, the TiNiV memorial alloy is pressed into sheet material, the 2nd, the cold material that draws wire, the size of two kinds of specifications can be decided according to engine request.
In the above-mentioned cold deformation weight range, the cold deformation amount is in the 15%-40% scope, and TiNiV memorial alloy phase transition temperature and original transformation temperature differ little.
Description of drawings
Fig. 1 cold deformation amount is to the influence of TiNiV memorial alloy phase transition temperature
Can be found out that by Fig. 1 with the increase of cold deformation amount, the TiNiV memorial alloy phase transition temperature can raise, the cold deformation amount is that 15% o'clock transformation temperature reaches maximum.The cold deformation amount is after 15%, and the TiNiV memorial alloy phase transition temperature begins to descend, and reduces with the difference of original transformation temperature.The cold deformation amount is in the 15%-40% scope, and TiNiV memorial alloy phase transition temperature and original transformation temperature differ little.
Embodiment
Comparative Examples:
When the TiNiV memorial alloy was not handled through the cold deformation amount, the original transformation temperature of TiNiV memorial alloy was seen table 1.
Embodiment 1:
Processing reaches at 15% o'clock through the cold deformation amount with the TiNiV memorial alloy, and the TiNiV memorial alloy phase transition temperature is raised to vertex, sees table 1.
Embodiment 2:
The TiNiV memorial alloy is handled greater than after 25% through the cold deformation amount, and TiNiV memorial alloy phase transition temperature and original transformation temperature differ little, see table 1.
Table 1 is through the transformation temperature of the TiNiV memorial alloy of different cold deformation amounts processing
| Cold deformation amount (%) | As（℃） | Af（℃） | Ms（℃） | Mf（℃） |
| 0 | -1.0 | 4.9 | -10 | -11.3 |
| 5 | 3.8 | 7.0 | -8.5 | -10.2 |
| 10 | 3.5 | 6.8 | -8.7 | -10.3 |
| 15 | 2.8 | 6.0 | -9.2 | -10.6 |
| 25 | 0.0 | 5.5 | -9.5 | -11.0 |
| 40 | -1.8 | 4.5 | -10.5 | -11.8 |
Claims (2)
