Application field and characteristics of Grade 5 titanium rod,Grade 5 plate

1. Grade5  titanium rod (TI-6AL-4V) belongs to α+β alloy with large dosage.

2. Grade5 titanium rod has good process performance. Its conventional thermal deformation is carried out in the two-phase region, and the deformation amount must be more than 50% to transform the coarse original weihterite structure into isometric structure.

3, Grade 5 titanium bar after deformation processing, according to different needs, can use stress annealing (9oo℃ heat preservation, air cooling), common annealing (700 ℃ heat preservation, air cooling), recrystallization annealing (940℃ heat preservation furnace cooling to 480℃ air cooling) and double annealing (940℃ heat preservation air cooling +700℃ heat preservation air cooling) heat treatment process.The microstructure obtained by stress relieving annealing and ordinary annealing is non-recrystallization or partial recrystallization with high strength.After recrystallization annealing the isometric axes are obtained.A + intercrystalline beta structure, good plasticity;Double shaft such as α+β organization after annealing, close to the binary organization form, has good comprehensive performance (Qb about 900 an 1000 mpa, ¢for 10%, bits of about 35% 45%).

GR5 titanium plate

4. Grade5 titanium rod can be strengthened by 20% to 30% by heat treatment.It is generally believed that aging at 850℃- 950℃ can obtain the proper amount of primary alpha microstructure and better comprehensive properties.Grade5 alloy has a poor quenching permeability, and the cross section of parts with enhanced heat treatment is generally no more than 40 mm.

5. Grade titanium alloy has good weldability, and the temperature of the weld zone is not lower than 90% of the matrix;The plasticity is also similar to that of tsuen metal.

6, Grade5 alloy corrosion resistance close to pure titanium, can work for a long time below 400℃, short time :L temperature can reach 700℃ to 750℃ when the content of oxygen and nitrogen in the alloy at a low level, Gr23 alloy can also maintain a good plasticity at- I 96℃, can be used to make low temperature and high pressure vessels.
