Abstract

The results of a study of industrially melted orthorhombic titanium alloy VIT1 showed that these alloys are prone to hydrogen embrittlement, formation of surface and internal intergranular cracks, embrittlement of grain boundaries during deformation due to microsegregation of alloying elements to grain boundaries, and low-ductility or brittle fracture of blade forgings.
