Effect of Ta Additions on the Microstructure, Damping, and Shape Memory Behaviour of Prealloyed Cu-Al-Ni Shape Memory Alloys
The influence of Ta additions on the microstructure and properties of Cu-Al-Ni shape memory alloys was investigated in this paper. The addition of Ta significantly affects the green and porosity densities; the minimum percentage of porosity was observed with the modified prealloyed Cu-Al-Ni-2.0 wt.% Ta. The phase transformation temperatures were shifted towards the highest values after Ta was a...
متن کاملElectrodeposition of Thin Film Cu-Zn Shape Memory Alloys
Cu-Zn alloys have been electrodeposited from a pyrophosphate electrolyte containing Cu2P207> Zn2P207 salts and an excess of K4P2O7 and KN03. Current-potential data for both copper and zinc, as well their plating current efficiencies were determined from electrochemical polarisation experiments. Copper deposition commenced at potentials below -0.208 V whereas zinc was deposited only below -1.157...
متن کاملShape Memory Properties in Cu-Zn-Al Alloy
In this research a Cu-Zn-Al alloy is produced by melting the raw materials in an electric resistance furnace and then pouring it into a steel mould. The optimum way to achieve the final analysis in the hypo-eutectoid range is determined and the influence of the alloying element, Ti on the grain size and the shape memory properties of the samples are investigated. Solution treatment (done at 850...

متن کاملShape Memory Effect in Diffusion Bonded Cu Base Shape Memory Alloys/Steel Interfaces
In many applications, Cu base Shape Memory Alloys (SMA S) are a more economical alternative to other systems showing Shape Memory Effect (SME). However, bearing in mind the potential use of these SMA it is becoming increasingly important to develop suitable techniques to join them satisfactorily to themselves and to another material. In that sense, a liquid phase diffusion bonding process with ...
