A comprehensive method is proposed for predicting the deformation of ceramic products under their own weight (the force of gravity) during sintering. The method is based on the torsion of thin-walled tubes, finite-element modeling, a calibration process that includes tests of specimens of the material in cantilever bending, and validation of the numerical solution. The method can be used to predict the deformation of thin-walled and solid products made of materials whose rheology is based on the mechanisms of viscous and/or diffusion flow. © 2014 Springer Science+Business Media New York.

This article examines the processes that take place during the cutting of Bakor with a diamond tool in which the diamond-bearing layer has a clustered structure. Such a structure ensures more uniform loading of the cutting granules, which improves the cutting ability of the segments and increases the service life of the tool. © 2011 Springer Science+Business Media, Inc.

Analysis of published data was performed on the basis of solvation energies of a number of "transition" and "soft" cations. A dependence of the solvation energy of cations on the donor and acceptor numbers of the solvent was derived. Donor and acceptor ability parameters of Mn 2+, Co2+, Ni2+, Cu2+, Zn 2+, Ag+, Cd2+, and Tl+ were calculated. The resultant parameters were used to calculate the extraction constants of the specified cations with di-2-ethylhexyl-phosphoric acid (DEHPA) solution in neutral solvents; the model represented has a good predictive power. © Pleiades Publishing, Ltd., 2010.
