A theory of transient creep in L12 intermetallic alloys which exhibited a yield-strength anomaly was presented. The theory was based upon the hypothesis that mobile a<101>  super-dislocations underwent a pinning-depinning transition and exhibited a critical behavior at a critical stress. An areal-velocity scaling function was introduced, which described the average time-dependent velocity profile of a dislocation as it propagated through the crystal. It was suggested that the measurement of transient creep permitted the determination of information concerning the deformation history of the sample.
