HEAT TREATMENT

• When high hardness, tensile strength, and fatigue strength are required, annealing can be performed at 1,700-1,900°F (927 – 1,038°C).
  DAXUN 6-4™ Grade 5 alloy can be heat treated in a variety of ways.
• 1. Anneal: 1,275 -1,400°F; (691 – 760°C), ½ to 2 hours, air or furnace cool
• 2. Stress Relief Anneal: 1,000 -1,200°F; (538 – 649°C), 1 to 8 hours, air or furnace cool
• 3. Solution Heat Treat: 1,675 -1,750°F; (913 – 954°C), 1 hour, water quench
• 4. Aging: 975 -1,025°F; (524 – 552°C), 4 to 8 hours – air cool

In the solution treated and aged condition, rapid quenching of small sections yields optimum properties. Larger section sizes and/or delayed quenching may result in less than optimum properties.

HARDNESS

Typical hardness in the annealed condition is Rockwell C 30-34, and about Rockwell C 35-39 in the solution and aged condition.

Forgeability/Formability

• Ti-6Al-4V, Grade 5 alloy bar is forged at 1,750°F; (954°C) with a final forging temperature of 1,450°F; (788°C). A minimum of 35% reduction is recommended for optimum properties.
• Ti-6Al-4V, Grade 5 alloy bar is difficult to form at room temperature, even in the annealed condition. Therefore, severe forming operations such as bending or stretching can be performed on annealed material at temperatures up to 1,200°F; (649°C) without affecting mechanical properties. Hot sizing or forming can be accomplished by creep forming in the range of 1,000 – 1,200°F; (538 – 649°C).

Machinability

Ti-6Al-4V, Grade 5 alloy bar can be machined using austenitic stainless steel machining methods with slow machining speeds, high feeds, rigid tools, and the use of large amounts of non-chlorinated cutting fluids.

Weldability

Ti-6Al-4V, Grade 5 alloy rod is readily weldable in the annealed condition or in the solution and partially aged condition, with aging being accomplished during post weld heat treatment. Precautions must be taken to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding may be performed in an inert gas filled chamber or with inert gas to weld the molten metal and adjacent heated zones, with a tail shield. Spot, seam, and flash welding may be performed without the aid of a protective atmosphere.

Special Considerations

Ti-6Al-4V, Grade 5 titanium alloy rod may be contaminated with hydrogen from improper pickling, and with oxygen, nitrogen, and carbon during forging, heat treating, brazing, etc. This contamination may result in a loss of ductility, which may adversely affect notch sensitivity and forming characteristics.
