Cyclic-Strain Resistivity in Pure Aluminum at 20 K
- Additional Document Info

Strain induced resistivity increases are examined in nominal 99.99 and 99.999% pure aluminum under conditions of cyclic strain at 20 K. Samples having residual resistivity ratios (RRR = (273 K)/(4.2 K)) of 1000, 2420 and 9440 were prepared by cold working and annealing bars originally 25.4 mm in diameter. Constant strain range (r) tests were performed for 0.05%
