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.

Presented is the state-of-the-art of production of semi-products and products of titanium and its alloys in Ukraine. The rod of titanium and its alloy is one of the mostly demanded semi-products. In Ukraine the titanium rods are not manufactured in principle. For its mass production it is necessary to reduce the cost of technology for their production. The production of rod semi-products by using methods of powder metallurgy in applying of powders with the developed surface and welding was grounded. Peculiarities of application of different methods of welding were considered, the application of pressure welding was shown as challenging. The optimum one is the rotation friction welding for production of rod semi-products. The main problems, which may occur in friction welding of sintered semi-products, were considered, the need in further investigations of weldability of the given semi-products was shown. 51 Ref.
