The creep strength of battery grids, expanded from drum-cast low-antimony lead alloy tip, wa varied by heat-treatments at several temperature. Grid growth following potentiostatic corrosion was found to be highly anisotropic. In spite of an increase in length, there wa a decrease in width. A theoretical analysis indicated that growth of expanded grids consisted of two components: an increase in the wire length (wire elongation), and a change in the grid shape (grid shear). The rate of the wire elongation is the corrosion test was found to be inversely related to the grid creep strength, and the deformation mechanism was identified as power-law creep. It is shown that, in order to meaningfully compare grid growths, the geometrical environment of grid test samples must be carefully controlled.
