The density of titanium alloys is generally around (4.51 g/cm3) and is
only 60% of steel.
The density of titanium material is generally calculated according to the
density of 4.51g/cm3. However, titanium alloy because of different grades, the
material element content is different, different grades of titanium alloy
density will be slightly different.
First, the type of titanium alloy:
At room temperature, titanium alloy has three substrate tissues, titanium
can be divided into the following three categories: α alloy, (α plus β) alloy
and β alloy. Ta, TC and TB are represented in China.
1, α alloy
It is a single-phase alloy composed of α phase-solids, whether at general
temperature or at higher actual application temperature, is α phase, stable
tissue, wear resistance is higher than pure titanium, strong antioxidant
capacity. At a temperature of 500 degrees C to 600 degrees C, its strength and
creep resistance are still maintained, but heat treatment cannot be
strengthened, and room temperature strength is not high.
2, β alloy
It is a single-phase alloy composed of β phase-solid solubles, which has
a high strength without heat treatment, is further strengthened after quenching
and aging, and the room temperature strength can reach 1372 to 1666 MPa;
However, the thermal stability is poor and should not be used at high
3, α and β alloy
It is a two-phase alloy, with good comprehensive performance, good
organizational stability, good toughness, plasticity and high temperature
deformation performance, can be better heat pressure processing, quenching,
aging to strengthen the alloy. The intensity after heat treatment is about 50%
to 100% higher than the annealing state. High temperature strength, can be in
400 degrees C to 500 degrees C temperature for long-term operation, its thermal
stability is lower than α alloy.
