ABSTRACT:
Oxygen is incorporated into an FeTiMn granulate in an amount sufficient to form double oxides of titanium and manganese therein, but insufficient to form oxides containing iron. As the result, the granules are embrittled, favoring the formation of microcracks to such an extent that activation of the granules by hydrogen takes place, after initial evacuation, at room temperature, after which the granulate can be used in a pressure container for storage and discharge of hydrogen and/or deuterium over long periods of operation. The oxygen content is to be kept in an atomic ratio with reference to the manganese content of the alloy lying between 1:3 and 1:3.5 and the ratio of titanium not bound by formation of a metal oxide to the iron should be equal to or greater than 1:1 on an atomic basis, with the FeTi content of the alloy constituting 90 to 95% by weight of the alloy.
