Titanium titanium alloys research at the institute for non-ferrous and rare metals, bucharest, romania

摘要

The research work performed within the Institute forNon-ferrous and Rare Metals of Bucharest, Romania was focusedon the development of technologies for obtaining titanium fromdomestic raw materials, producing different titanium alloys and,also, on turning of the titanium and titanium alloys in to semi-finished products. For the titanium industry, we have producedcomplete technologies to process titanium slags throughchlorination, purification and magnesiothermic reduction of thetitanium chloride.Titanium and titanium alloys ingots were obtained by electronbeam melting and by consumable electrode arc melting of thetitanium sponge and pre-alloyed materials. Our research hascontinued with the processing of these ingots in rods, sheets, tubes,wires, and cast products.According to the Romanian industry needs, the research work inthe field of titanium and titanium alloys was directed to theapplications for medical use, chemical industry, naval applicationsand aircraft buildings. At the same time, we have developedtitanium metal scrap processing technologies through molten saltelectrolysis and we have obtained titanium metal powders. Wehave, also, obtained titanium metal powders via a hydrogenation-dehydrogenation process. Recently, our Institute has developedresearch programs in the areas of new corrosion resistant titaniumalloys, intermetallic compounds and titanium-matrix composites.
