Effect of Aging on Corrosion Behavior of Martensite Phase in Cu-Al-Be Shape Memory Alloy

Al-Haidary JT, Mastafa AM and Hamza AZ

The corrosion behavior of martensite phase in Cu-Al-Be shape memory alloy with aging at 150°C at different time and quenching media study by open circuit potential, tafal polarization and cyclic polarization. The microstructure of martensite study by optical microscope and x-ray diffraction (XRD) and transformation temperature was determined by Differential Scanning Calorimeter (DSC). The result show aging martensite at 150°C at 2 and 4 h have high open circuit potential, low corrosion current density, high corrosion potential and pitting potential than martensite without aging.
