DYNAMICS OF RESIDUAL STRESS FORMATION IN GLASS AND ITS MODELING

For the purpose of mathematical modeling of the process ofstressformation in glass, 6x25x100 mmfloat glasssampleswere tempered. During thetemperingthe change ofstresses and thetemperature ofinner and outer layers of glasswerefilmed witha digital camera.Obtainedresults almost completely coincided with the results obtained by R. Gardon.

Regulation of the phase-structural composition and metastability of austenite by alloying elements and parameters of tempering for increase wear-resistance of Fe-Cr-Mn deposited steel

It is shown that under the influence of alloying (Cr, Mn, C, Si, Ti, N, V) during electric arc hardfacing with a flux cored wire, as well as technological tempering parameters at temperatures of 300...700°C, the phase-structural composition of the cost-saving alloyed deposited steel (from 0 to 75 % quenching martensite and austenite), the degree of metastability of austenite are regulated.
