Effect of parameters of heat treatment of steel 20 microalloyed with vanadium on its microstructure and mechanical properties has been studied. It has been shown that the normalization performed before quenching from the ...

The effect of nitrogen, silicon, and aging modes on the structure, resistance to abrasive and adhesive wear, friction factor, and mechanical properties of nitrogen-bearing (0.27-0.83% N) chromium-manganese austenitic steels ...

Aim. To test the effect of the assisted training tools on the most important indicators affecting speed development and the results in 100 and 200 min junior sprinters. Particular tasks were chosen to test the effect of ...

Results are provided for a study of the effect of pitch additions of a different nature on binder properties and refractory material quality in the production of periclase-carbon refractories. The desirability is established ...

The authors construct the thermokinetic diagram describing the decomposition of supercooled austenite in steel 05G2MFB and analyze the effect of cooling rate on the structure of this steel. The mechanical properties of the ...

Aim. The article deals with establishing the features of changes in the morphological parameters of women aged 30-40 years involved in different fitness programs at the basic stage. Materials and methods. 85 women aged ...

Mechanical properties of pipe steel 07G2MFB are studied after cooling from the austenitic region at rates of 0.9-32°C/sec making it possible to obtain a ferrite-bainite structure with different ratios of structural components. ...

The most widespread procedure for the synthesis of oxyhydrate materials by the sol-gel method is fast alkaline hydrolysis of the soluble salts of heavy metals. Oversaturation of the mother solution during fast hydrolysis ...
