Abstract

Mechanical properties of nanostructure (NS) and microcrystalline (MS) VT6 titanium alloy specimens after pressure welding at the range temperature from 600 oС to 900 oС are studied.  It is shown, that temperature raise of pressure welding results in increasing of the solid-phase joint impact toughness. The tests performed reveal apparent interrelationship between impact microstrength and fracture pattern and structure in the bond zone.
