Single crystals of zone-refined lead were deformed in tension at 4.2 to 273K, and at strain-rates ranging over 4 orders of magnitude at 77K. The three stages of deformation typical of a face-centered-cubic metal were observed. The characteristics of these stages were normal, except for the observation that stage-II was composed of two distinct regions of linear hardening. Stage-III was examined in order to determine the stacking-fault energy. A value of 25mJ/m2 was obtained.
