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.

Explosion treatment of metals in the modern sense is represented by different technological processes based on application of the energy of explosion, and allowing improvement of certain service properties of the metals or welded structures. PWI developed technologies of explosion treatment to improve the corrosion resistance, dimensional stability, cyclic fatigue life of welded structures, lower the residual stresses, eliminate defects of tank shape, and increase the strength, ductility, and cold resistance of low-carbon steels. The above technologies have high mobility and responsiveness, and are independent of the external energy sources. Their disadvantage is limited applicability of explosion in settlements and long-term process of obtaining permits. However, there is extensive experience of application of explosion treatment under the conditions of operating industrial production. 15 Ref., 6 Fig.
