Позорная война рф против Украины
Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The integrated works were carried out on investigation of feasibility for producing ingots of high-strength complex-alloyed titanium alloy VT22 of a primary charge.. Using technology of an electron beam cold hearth remelting and a portion supply of metal into a water-cooled mould the ingots of 400 mm diameter and up to 3 m length were produced, from which the semi-products in the form of plates and hot-pressed rods of 60 mm diameter were manufactured. Results of investigations of structure and mechanical properties of semi-products, made of titanium alloy VT22 ingots. are presented. It was found that the metal of produced ingots and semi-products is in compliance with requirements of standards both by the chemical composition and also by the structure and mechanical properties. Moreover, the material is characterized by a good ductility at high strength characteristics. It is shown that the electron beam technology is an effective method for producing the complex-alloyed alloys of titanium. 12 Ref, 4 Tabl., 11 Fig.
