Description

Relative measurements of real and imaginary reluctances were made as a function of sample thickness on both rolled and cast 6061 aluminum samples using an ac magnetic bridge. Samples were both nonannealed and annealed. Evidence was developed that the imaginary reluctance (which is shown here to respond to the conductivity of samples) responds more to the bulk properties of the samples while real reluctance apparently responds more to surface conditions such as surface residual stress.

Comparisons of the Behavior of Real and Imaginary Reluctances Between Samples of 6061 Aluminum as a Function of Grain Size
