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 results of studying the influence of the modifier of the Al–Ti–C system, obtained by high-voltage electric discharge treatment in a hydrocarbon liquid, on the structure and properties of the cast AK7pch (A357) alloy are presented. The prospects for the use of a modifier produced by the method of a high-voltage electric discharge treatment of metal powders to improve the structure of cast alloys and weld metal are shown. 25 Ref., 1 Table, 4 Figures.
Keywords: welded joint, weld metal, high-voltage electric discharge, modifier of the structure of cast alloys, metallurgy, dispersion, carbidization
