Romashkin V.N., Nuraliyev F.A., Stepashkin Y.A., Valisovsky I.V. Introduction to the Thermomechanics of Disintegration of Molding Sands
Presented concept of the mechanism and especially the destruction of cold-forming mixtures, as well as their influence on the formation of various kinds of defects (assignment over, uzhiminy, burnt, polluting). As a result, studies of real thermal conditions mold examined the factors causing the destruction of the mold. The proposed theoretical scheme to destroy the surface layers of thermal stresses can form an idea of the nature of formed surface defects.
Key words: mold, destruction, defects, durability, heat resistance

Sharikov P.V. New Methods of Eliminating Bell Defects
The article describes a new method of repairing cracked bronze bells by sealing a through crack from environment and heating the product in a gas-static unit in a neutral gas medium at a pressure of 1000…2000 atm to plastic deformation temperature followed by dwelling, cooling and pressure relief to initial parameters according to a special schedule. As a result, diffusion welding of the crack and material densification to "pseudowrought" occurs. At the same time, in this method, internal defects in the form of various discontinuities are eliminated, material elasticity and strength are increased, and the bell's sounding is improved. This method has limitations by crack width and because of the size of the loading basket of the gas-static unit. The process has been patented.
Key words: bell, crack, repair, heat treatment, diffusion welding, gas-static unit, correction, internal casting defects, discontinuities, pseudowrought.
