Abstract

The issues of development and research of prospective titanium alloys are in focus from the point of view of «economical» alloyage approach. The properties of low-cost titanium alloys developed in FSUE «VIAM» are shown in comparison with foreign analogues. The features of cast alloy VT40L (Ti–Al–V–Mo–Fe–Si) and new structural alloys VT44 (Ti–Al–REE) and VT45 (Ti–Al–V–Fe–REE) are considered, the two latter alloys are designed both for independent use in low- and medium-strained constructions and for titanium-polymer laminates which give opportunity to provide with 20 percent weight reduction comparing to that of bulk-metal constructions with the same load bearing capacity. It is shown that the new near-α and (α+β) REE-containing alloys have improved mechanical and service properties.
