The properties of deformed titanium pseudo-alpha-alloys of type PT3V with boron additives are investigated. It is shown that boron produces a positive action on the toughness and ductility of the alloys. The anisotropy of the impact toughness of the alloys is lowered due to a considerable decrease in the size of the colonies of α + β phases in the structure. Determination of the crystallographic orientation of the α-phase plates and of the metallographic orientation of the β-phase layers in flat preforms of titanium alloys has made it possible to index the habit planes between the α- and β-phases.
