Products Description

GR5 Overview

GR5 alloy is a medium-strength α-β two-phase titanium alloy containing 6% of the α-stabilizing element AI and 4% of the β-stabilizing element V. The alloy has an excellent combination of properties, and is most widely used in the aviation and aerospace industries. The alloy has a long working temperature of up to 400°C. In the aerospace industry, it is mainly used for the manufacture of engine fans and compressor disks and blades, as well as important load-bearing components such as beams, joints and spacer frames in the structure of aircraft.

The main semi-finished products of GR5 titanium alloy are bars, forgings, thick plates, thin plates, profiles and wires. The alloy is mainly used in the annealed condition and can also be strengthened to some extent by solid solution aging, however the hardened cross section is generally not more than 25mm.

The alloy has good process plasticity and superplasticity and is suitable for a wide range of pressure machining and forming. The alloy can also be welded and machined in various ways.

GR5 titanium alloy chemical composition.

GR5 containing titanium (Ti) balance, iron (Fe) ≤ 0.30, carbon (C) ≤ 0.10, nitrogen (N) ≤ 0.05, hydrogen (H) ≤ 0.015, oxygen (O) ≤ 0.20, aluminum (Al) 5.5 ~ 6.8, vanadium (V) 3.5 ~ 4.5.

GR5 heat treatment system

1) Annealing

Plate: 700-850 ℃, 0.5-2h, air cooling; bar and forgings: 700-800 ℃, 1-2h, air cooling.

(2) vacuum annealing

700-800 ℃, 0.5-2h, furnace cooling to 200 ° C or less allowed out of the air-cooled. Absolute pressure in the furnace should not be greater than 0.09Pa.

(3) solid solution treatment

910-940 ° C, 0.5-2h, water quenching.

4)Ageing

520-550°C, 2-4h, air cooling.

5)Stress-relief annealing

Complete stress relief annealing: 600-650°C, 1-4h, air cooling; incomplete stress relief annealing: 500-600°C, 0.5-3h, air cooling. Stress relief annealing can be carried out in the air furnace or vacuum furnace.
