Low-Temperature Deformation of Copper Single Crystals

T. H. Blewitt、R. R. Coltman、J. K. Redman1957-06-01OpenAlex

Single crystals of copper were deformed at 4.2°K and 77.3°K. At 4.2°K, after a large strain produced by normal slip, jerky flow (discontinuous slip) occurs. From the study of reactor irradiated crystals, it was deduced that a packet of 30 slip lines, each containing 104 dislocations, was released to form each jerk of…

Scattering by an Inhomogeneous Solid. II. The Correlation Function and Its Application

P. Debye、H. R. Anderson、H. Brumberger1957-06-01OpenAlex

Experiments on the angular intensity distribution of x-rays scattered by porous materials (hole structures) in the range of small angles are described. It is shown that the scattering can be characterized by an exponential correlation function in the case of a distribution of holes of random shape and size in solid; a…
