Abstract
Laser interferometry is used to study micrometer-scale creep-strain nonuniformities (jumps) that occur during compression of metals (Ag, Al, Bi, Cu, Pb, Sn, Zn) and LiF: Mg crystals. The strain rate is found to vary periodically. The average magnitude of deformation L over one period and the variation of L with the total strain are determined. Correlations are found to exist between L and the Mg content in the LiF crystals, between L and the grain size in the metals, and between the magnitude of small jumps and the Burgers vector in the metals.
