TİTANYUM GR5 (6Al-4V, Ti 6-4, UNS R56400, GR.5)

Ti 6Al-4V, Titanium Gr5 alloy (UNS R56400) is the most widely used titanium alloy. Alpha is a two-phase α + β titanium alloy containing vanadium as the stabilizer and aluminum as the beta stabilizer. This high strength alloy can be used in temperatures from 427 ° C (800 ° F) to freezing cold environments.

Ti 6Al-4V, Titanium Gr5 alloy, in annealed condition and solution hardened and aged. This alloy is produced by primary melting using vacuum (VAR), electron beam (EB) or plasma arc furnace melting (PAM). Re-melting is carried out by one or two vacuum arc steps.

Ti 6Al-4V, Titanium Gr5 Heat Treatment

Tempering at 1,700-1,900 ° F (927 – 1,038 ° C), high hardness, tensile and fatigue strength is required.

Ti 6Al-4V, Titanium Gr5 alloy can be subjected to heat treatment in various ways.

1. Annealing: 1,275 -1,400 ° F; (691 – 760 ° C), ½ – 2 hours, cooling in air or oven environment
2. Stress relief annealing: 1,000 – 1,200 ° F; (538 – 649 ° C), 1 – 8 hours, cooling in air or oven environment
3. Solution heat treatment: 1,675 -1,750 ° F; (913 – 954 ° C), 1 hour quenching
4. Aging heat treatment: 975 -1.025 ° F; (524 – 552 ° C), 4-8 hours – air cooling

The best possible properties in solution and aging applications are in parts with small cross sections which are rapidly watered. Large cross-section parts and / or a delay in water supply can lead to loss of the highest achievable levels.

Typical hardness in the annealed state for Ti 6Al-4V, Titanium Gr5 is Rockwell C 30-34 and Rockwell C 35-39 for solution and aging and solution hardening.
