METHOD FOR MAKING SHEETS OF MAGNESIUM-BASE ALLOY FOR ELECTROCHEMICAL ELECTRIC CURRENT SOURCES Russian patent published in 2005 - IPC

FIELD: plastic working of special magnesium base alloys alloyed with elements capable to easy evaporation or to generation at deformation oxides hazard for environment, possibly manufacture of rolled sheets used for making anodes of electrochemical current sources.

SUBSTANCE: method comprises steps of preliminarily deforming heated blank of magnesium base alloy and warm rolling of preliminarily deformed blank for producing sheet; before preliminary deformation placing magnesium alloy blank into envelope of aluminum (Al-Mg-Si system) alloy without sealing. Length of envelope exceeds length of blank at least by 10%. Preliminary deformation is realized by hot rolling or upsetting in die set according to configuration of blank.

EFFECT: production of sheets with electrochemical properties uniform along the whole cross section and with enhanced surface quality, safety labor condition due to preventing evaporation of mercury, toxic oxides and other compounds containing mercury, thallium, gallium, cadmium.
