Shape 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 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 کاملDamping Characteristics of Inherent and Intrinsic Internal Friction of Cu-Zn-Al Shape Memory Alloys
Damping properties of the inherent and intrinsic internal friction peaks (IFPT + IFI) of Cu-xZn-11Al (x = 7.0, 7.5, 8.0, 8.5, and 9.0 wt. %) shape memory alloys (SMAs) were investigated by using dynamic mechanical analysis. The Cu-7.5Zn-11Al, Cu-8.0Zn-11Al, and Cu-8.5Zn-11Al SMAs with (IFPT + IFI)β3(L21)→γ′ 3(2H) peaks exhibit higher damping capacity than the Cu-7.0Zn-11Al SMA with a (IFPT + IF...
متن کاملMagnetoelasticity and Magnetoresistance in Cu–Al–Mn Shape-Memory Alloys
This paper is aimed at studying the effect of a magnetic field on the martensitic transition of a Cu–Al–Mn shape-memory alloy. The martensitic transition has been studied through resistance measurements under applied magnetic fields ranging from 0 to 50 kOe. Negative magnetoresistance showing an almost linear dependence with the square of the magnetization has been observed. This magnetoresisti...
