Abstract

Titanium is the material of choice for high performances components, due to the combination of physical and mechanical properties. Nevertheless, it is also characterized by very high production costs. One way to reduce the cost of titanium is to use cheaper alloying elements instead of vanadium or niobium to stabilize the body-centered-cubic β-phase. TIG-welding of low-cost titanium alloys is complicated due to the high content of alloying elements, as well as the use of oxygen as an alloying element.
