A Vacancy Model of Pore Annihilation During Hot Isostatic Pressing of Single Crystals of Nickel-Base Superalloys
An improved diffusion model of pore annihilation during hot isostatic pressing of single crystals of nickel-base superalloys is proposed. The model considers dissolution of pores by emission of vacancies and t...

Growth kinetics of particles of nitrides in process of high-temperature volume nitriding of wrought alloy of Ni-Co-Cr-W-Ti system
The laws of nitride phase formation are studied for the Ni-Co-Cr-W-Ti new class heat-resistant alloy, strengthened by volume nitriding. The data on kinetic features of behavior of the alloy during thermochemic...

Apparently complete grain boundary wetting in Cu–In alloys
The transition from incomplete to complete grain boundary (GB) wetting has been studied in the (Cu) + L region of the Cu–In phase diagram in the broad interval of In concentrations from 4 to 22 wt% In. The num...

Grain-boundary diffusion of germanium in copper and Cu-Ge and Cu-Fe alloys
The grain-boundary diffusion (GBD) of germanium in copper and its alloys Cu-2% Ge and Cu-0.5% Fe is investigated in the temperature range of 500–590°C by means of electron-probe microanalysis. The GBD paramete...

Segregation Effect and its Influence on Grain Boundary Diffusion in Thin Metallic Films
The diffusion in Au-Cu and Pt-Cu thin films has been studied by Rutherford backscattering spectrometry (RBS) under the kinetic regime “B” (within the temperature interval of 175–290°C) and “C” (room temperatur...
