Abstract A brief survey is given of recent applications of electrode potential measurements for the study of the corrosion of metals and alloys in the presence of aqueous solutions, molten salts and gaseous atmospheres. Particularly considered are: (1) cathodic and anodic protection of passivable metals and alloys in the presence of chloride containing solutions; (2) pitting corrosion of copper in the presence of cold water; (3) stress corrosion cracking of titanium alloys in the presence of aqueous solutions; (4) diagrams of electrochemical equilibria in the presence of molten carbonates, as a function of the electrode potential and of log PCO2 or log O−−; (5) diagrams of chemical and electrochemical equilibria in the presence of gaseous oxygen as a function of ΔG° or the electrode potential E, and of temperature T; (6) diagrams of electrochemical equilibria of semi-conductive oxides, as a function of the electrode potential E, and of log O−−. Mention is made of the possible usefulness of these three last types of diagrams for studying problems related to corrosion, fuel cells, and high temperature electrochemistry.

A variety of materials containing many different microstructures have been examined with the USS MVEM. Three topics have been selected to illustrate some of the more recent studies of diffraction phenomena and defect, grain and multi-phase structures of metals and minerals.(1) Critical Voltage Effects in Metals and Alloys - This many-beam dynamical diffraction phenomenon, in which some Bragg resonances vanish at certain accelerating voltages, Vc, depends sensitively on the spacing of diffracting planes, Debye temperature θD and structure factors. Vc values can be measured to ± 0.5% in the HVEM ana used to obtain improved extinction distances and θD values appropriate to electron diffraction, as well as to probe local bonding effects and composition variations in alloys.
