Shape memory alloy characterization with the TESCAN LYRA3 FIB-SEM
In the present study the corrosion behaviour of a β CuAlBe shape memory alloy containing stress-induced martensite in a 3.5% NaCl solution adjusted to pH 8 was analyzed, in view of its application as seismic dampers in bridges. This condition is intended to be a simple approximation for a sea water environment. The element distribution maps of samples were obtained using ToF-SIMS analysis while EBSD analysis was performed to investigate grain orientation and phases present in the studied samples. The TESCAN LYRA3 Focused Ion Beam Scanning Electron Microscope equipped with a ToF-SIMS analyzer and an EBSD camera was used for such analyses.
