On the ductile-to-brittle transition in ice under compression
Abstract Evidence is presented which supports a recent model [Schulson, Acta metall. mater.38, 1963 (1990)] of the ductile-brittle transition in ice under uniaxial compression. Observations onExpand

The influence of columnar defects on the vortex array in Bi2Sr2CaCu2O8+x single crystals
Abstract Using a decoration technique, the influence of artificial columnar defects on the vortex lattice in BSCCO single crystals was investigated. A transition from a fully disordered to aExpand
Defect states in Si containing dislocation nets
Dc conductivity, Hall effect, and photoluminescence spectra are studied in heavily deformed samples containing a connected system of dislocation cell walls. The conclusion is made that, in deformedExpand
