Abstract
The invention relates to a moderate-heat treatment method for controlling TiNi base memorial alloy phase transition temperature, which is characterized in that the alloy is respectively subjected to moderate-heat treatment at the temperature of 400 DEG C, 430 DEG C, 460 DEG C, 490 DEG C and 520 DEG C for 5-25 min. When the temperature of the moderate-heat treatment is 430 DEG C and the treatment time is 15 min, the phase transition temperature and the original phase transition temperature of the TiNi base memorial alloy have a minimum difference.
Description
Technical field
The present invention relates to the shape memory alloy technical field, particularly a kind of control the TiNi base memorial alloy phase transition temperature in warm treatment process.
Background technology
Warm processing during the TiNi base memorial alloy will pass through in process of production, thereby guarantee that this alloy has shape memory effect, yet, the TiNi base memorial alloy through in after the warm processing, the transformation temperature of memorial alloy can change, this just causes TiNi base memorial alloy transformation temperature instability in application process, and the relation of warm processing and transformation temperature is most important in therefore finding out.
The present invention is directed to this problem, develop a kind of TiNi of control base memorial alloy phase transition temperature in warm treatment process.Through inquiry, not seeing has relevant patent to deliver.
Summary of the invention
The present invention relates to a kind of TiNi of control base memorial alloy phase transition temperature in warm treatment process.It is characterized in that: respectively through warm processing in 400 ℃, 430 ℃, 460 ℃, 490 ℃, 520 ℃, the treatment time is 5 minutes-25 minutes with alloy.
Warm treatment temp is 430 ℃ in above-mentioned, and the treatment time is 15 minutes, and it is minimum that TiNi base memorial alloy phase transition temperature and original transformation temperature differ.
Description of drawings
The relation of warm treatment temp and TiNi base memorial alloy phase transition temperature among Fig. 1
Embodiment
Comparative Examples:
During warm processing, the original transformation temperature of TiNi base memorial alloy did not see Table 1 during the TiNi base memorial alloy had
Embodiment 1:
When warm treatment temp is 400 ℃ in the TiNi base memorial alloy, the TiNi base memorial alloy phase transition temperature with in the rising of warm treatment temp, transformation temperature and original transformation temperature differ increase, see Table 1.
Embodiment 2:
When warm treatment temp was 430 ℃ in the TiNi base memorial alloy, it is minimum that TiNi base memorial alloy phase transition temperature and original transformation temperature differ, and sees Table 1.
Embodiment 3:
When warm treatment temp was 460 ℃ in the TiNi base memorial alloy, TiNi base memorial alloy phase transition temperature and original transformation temperature differed and begin and increase, and see Table 1.
Embodiment 4:
When warm treatment temp was 520 ℃ in the TiNi base memorial alloy, TiNi base memorial alloy phase transition temperature and original transformation temperature differed same increase, see Table 1.
Table 1TiNi base memorial alloy is through warm processing back transformation temperature in the difference
