    Abstract

    A simple constant stress tensile creep machine is described for use at very low stress levels. The initial mechanical advantage of the machine is 3:8 and the minimum feasible load is about 1.8 N. Some typical creep results are presented for an aluminum-5% magnesium alloy with measured steady-state strain rates down to about 10−9 s−1. It is demonstrated that the results obtained from this machine coincide with data from a normal creep machine at high stress levels, but the stress marking the experimental lower limit is reduced by more than one order of magnitude.
