WebResistivity of pure, metals at low temperatures. II 527 The only other case in metals where the resistance rises with falling temperature is in certain metals under the influence of a constant magnetic field, for instance in cadmium (cf. Milner I937). The explanation there is that the magneto-resistive effect WebCertain metals (e.g., iron, titanium, and nickel) are more susceptible to HE than others (e.g., copper, aluminum, and austenitic stainless steel). Removal of the metal from the source of hydrogen and heat treatment (to about 200°C) restores its mechanical properties.
