High-purity aluminum is often considered and sometimes used as the stabilizing material for practical composite superconductors. Such material has a residual resistivity ratio (RRR) in the range 1000-5000 when fully annealed. The authors investigated the effects of cyclic plastic strain at 4. 2 K. They also investigate the effects of annealing to room temperature on the RRR and magnetoresistance of aluminum covering a wide purity range. Measurements of mechanical hysteresis energy loss, anisotropic resistivity, and strain-induced magnetoresistance are reported. Selected experiments are described, and the implications of results on conductor operation are discussed.
