Abstract

Mechanical properties, phase composition, and structure of test melts of high-strength pseudo-β-titanium alloyed with yttrium and gadolinium are studied. Special features of the morphology of REM oxide particles and their distribution within the alloy structure are considered. Quantitative metallographic analysis of the structural components is conducted. Sizes of primary β-grains, volume fraction of secondary α-phase precipitates, secondary precipitate particle content, and α-phase shell thickness are determined. Test specimen fracture surfaces are analyzed, and presence of a ductile pitted relief is detected in fractures.
