Effect of the zone of plastic deformation of the fractal properties of a fracture surface

In order to determine the effect of the plastic zone on the fractal properties of a fracture surface, specimens of medium-carbon steels are studied after tough and brittle fracture. A fractal analysis is conducted for each specimen by the method of vertical sections. The sizes of the determining parameters of the fractures and plastic zones under the fracture surfaces are determined by measuring the Knoop microhardness.

Remelting of Iron Shavings with the Synergistic Effect of Minimum Metal Loss

Metallurgist - The well-known technologies of remelting iron shavings lead to significant (30%) losses of metal. An electroslag smelting furnace with graphite electrodes is proposed for remelting...     

Andreev Spectroscopy for Superconducting Phase Qubits

We propose a new method to measure the coherence time ofsuperconducting phase qubits based on the analysis of themagnetic-field dependent dc nonlinear Andreev current across ahigh-resistance tunnel contact between the qubit and a dirtymetal wire and derive a quantitative relation between thesubgap I–V characteristic and the internal correlationfunction of the qubit.
