The influence of microstructure on the corrosion resistance for some titanium-based alloys

This dataset contains scanning electron microscopy (SEM) micrographs revealing the microstructure of some Ti-based alloys, namely: Ti-6Al-4V (file name: TiV), Ti-6Al-7Nb (file name: TiNb) and TC21 (file name: TiAlSnZrMoCrNbSi) alloys and their localized corrosion as a result of passive layer breakdown in a corrosive environment, ie. 0.9% NaCl solution at temperature 37 deg.C. Two sets of micrographs were added, before and after a 7-day-long exposure to the above-mentioned environment. These micrographs were made on Hitachi S-3400N SEM in back-scattered electron mode, under an accelerating voltage of 20 kV.
