Abstract

High-temperature creep has been studied in lead and tin in the stress range of 10−6 to 10−4G over a range of temperatures near the melting point. A composite plot of dimensionless parameter•/γkT/DGb vsτ/G revealed a transition from a high stress region (with slope ∼4.9 for lead and ∼6.6 for tin) to a low stress region (with slope ∼1 for both metals), at stresses of ∼2 × 10-5G for lead and ∼10−5G for tin. The creep behavior in the low stress region is identical to that attributed to creep of the Harper-Dorn type. In addition, earlier work on aluminum in the low stress region is confirmed using polycrystalline as well as single crystal samples.
