The present invention relates to a shape memory alloy comprising the composition consisting of: - 30 to 53 wt.% of cobalt; - 18 to 35 wt.% of aluminum, and - 22 to 40 wt.% of iron and optionally unavoidable impurities.PATBERG, Lothar...
Ti-Ni basedshape memory alloyis the most useful of all kinds of shape memory alloys. But some principal problems of the alloys are exist in process of production working and heat treatment. Especially, it is expensive and difficult for forming[1], because of composition of alloy, heat treatme...
ThThis video demonstrates how shape memory alloys such as Nitonol, a nickel-titanium alloy work, returning to their original shape after having been deformed. This shape memory behaviour is thanks to the two possible crystal stuctures that they posssess.
Transformation temperatures of Ti-Ni shape memory alloys are highly sensitive to alloy composition. Therefore, it is essential to avoid composition variation or contamination during fabrication process of shape memory alloys. One of the key issues in the fabrication process is to control the ...
Workable high strength shape memory alloy A workable high strength shape memory alloys comprising:< P>< P>Al: 11.5-13.5%,Ni: 2-6%,< P>Mn: 1-5%, Ti: 0.1-5%,each on the weight basis, and the balance of Cu and inevitable impurities. In the modified alloy composition, the workabilit....
The shape memory alloy component76(FIG. 6) of the actuator32may be selected and configured, as by annealing and/or selection of metal composition of the SMA, such that at ambient temperature at or near sea level, or at relatively low altitudes (e.g., under 10,000 feet), the SMA actua...
The basis of the nickel-titanium shape memory alloy (SMA) class is the intermetallic equiatomic binary alloy NiTi. Thanks to its moderate solubility range, its composition can be changed, and it can be alloyed with other elements to alter both mechanical and shape memory properties. ...
the Advancement of Shape Memory Alloy Research and Technology is to compile the collective design experiences of our member organizations into a single medium that researchers and engineers may use to make efficient and effective decisions when developing shape memory alloy (SMA) components and systems...
Iron-based shape memory alloys are promising candidates for large-scale structural applications due to their cost efficiency and the possibility of using conventional processing routes from the steel industry. However, recently developed alloy systems li
