The above discussion of the spread of fresh slip in ionic crystals where the grown-in dislocations do not move in the process of deformation would appear to apply also to the generation of a Liiders band in the yield phenomenon of low carbon steel where the unpinning stress for aged dislocations is
Assuming a Debye frequency spectrum for beryllium and without making use of the incoherent approximation, the elastic and the one-phonon inelastic scattering and transport crosssections have been calculated as functions of neutron energy. The total calculated scattering crosssection is in good agree
## Abstract The thermal decomposition and etching of GaP have been investigated. The {111} GaP surfaces were treated in 10^โ2^โ10^โ5^ torr vacuum, and in hydrogen and argon atmosphere, in a temperature range of 900โ1300 K. Under the different experimental conditions the etched surfaces show differe
