A temperature change in elastic and acoustic properties of auricupride

Changes in acoustic and elastic properties of auricupride approach within the high temperature interval and close to an order-disorder phase transition have been discussed. Calculations of the phase velocities of purely transverse and longitudinal elastic waves, elastic moduli and Poisson's ratios based on elastic constants cij(T) of the crystal have been executed. Temperature changes of Grüneisen parameter along crystallographic directions [100], [110] and [111] have been defined

Influence of boric anhydride upon the physical and chemical properties of ferrosilicon slag

The authors study the influence of boric anhydride upon the physical and chemical properties of slag in the manufacture of ferrosilicon. It is established that adding boric anhydride to the slag changes its refractory quality and its viscosity and eases pouring slag and metal. Slags with optimal composition and properties are described

Thermodeformational Behavior of Cubic Crystals of Sodium Cyanide

In the paper the authors provide results of the study of anisotropic and isotropic acoustic (elastic waves propagation velocities), dimensional (elastic moduli) and nondimensional (Poisson's ratios) elastic characteristics of mono- and polycrystals of sodium cyanide within the temperature range 283.7±473 K

Three-Stage Character Of Molten Metal Drop And A Hard Substrate Contact Interaction

The paper presents the results of theoretical and experimental studies of the interaction between a molten metal drop and a solid metal substrate and justifies measures to avoid or to weaken this interaction
