Titanium Grade 5, also known as Ti6Al4VTi-6Al-4V or Ti 6-4, it is one of the most popular alloys in the titanium industry and accounts for almost half of the titanium used in the world today. 

Commonly referred to as Ti-6AL-4V (or Ti 6-4), this designation refers to its chemical composition of almost 90% titanium, 6% aluminum, 4% vanadium, 0.25% (max) iron  and 0.2% (max) oxygen. 

It features excellent strength, low modulus of elasticity, high corrosion resistance, good weldability and it is heat treatable.  The addition of aluminum and vanadium increases the hardness of the material in the alloy matrix, improving its physical and mechanical properties.

Weldability of Grade 5 Titanium : 

Grade 5 Alloy is easily welded in the annealed condition, or in the solution and partially aged condition, with aging being completed during the post weld heat treatment.

Precautions must be taken to prevent oxygen, nitrogen, and hydrogen contamination. Fusion welding can be done in inert gas filled chambers, or using inert gas welding of the molten metal and the adjacent heated zones using a trailing shield.

Spot, seam, and flash welding can be performed without resorting to protective atmospheres.

 

MACHINABILITY of Titanium Alloy Grade 5 

The alloy can be machined using practices for austenitic steels with slow speeds, heavy feeds, rigid tooling and large amounts of non-chlorinated cutting fluid

Heat Treatment 

  • Solution treat at 904-954 C(1660-1750 F) for 2 hours followed by water quench.

Forging 

  • Rough forge at 982 C(1800 F), finish at @ 968 C (1750 C).

Hot Working 

  • Hot forming will reduce both the springback and required forming forces, and will increase the overall ductility of the material.

Cold Working 

  • The cold working characteristics of this material are similar to those of austenitic stainless steels. In multiple forming operations, intermediate stress relieving is recommended to offset the alloy’s tendency to work harden. Post-work annealing is required to re-attain optimum performance characteristics.

Annealing 

  • Hold at 732 C(1350 F) between 1/4 and 4 hours, Furnace cool to 566 C(1050 F) then air cool. Furnace cooling is not required for forgings and bars.

Aging 

  • Age at 538 C (1000 F) for 4 hours, air cool.
