Heat Treatment

Types of titanium alloys:
At room temperature, titanium alloys have three matrix structures, and titanium can be divided into the following three categories: α alloys, (α+β) alloys and β alloys. In China, they are represented by TA, TC and TB respectively.

1. α alloy

It is a single-phase alloy composed of α-phase solid solution. Whether it is at normal temperature or at a higher practical application temperature, it is α-phase, with stable structure, higher wear resistance than pure titanium, and strong oxidation resistance. At a temperature of 500°C to 600°C, it still maintains its strength and creep resistance, but it cannot be strengthened by heat treatment, and its strength at room temperature is not high.

2. β alloy

It is a single-phase alloy composed of β-phase solid solution. It has high strength without heat treatment. After quenching and aging, the alloy is further strengthened, and the strength at room temperature can reach 1372-1666 MPa; but its thermal stability is poor, so it is not suitable for use at high temperatures. .

3. α+β alloy

It is a dual-phase alloy with good comprehensive properties, good structural stability, good toughness, plasticity and high-temperature deformation properties, and can be well processed by hot pressure, and can be quenched and aged to strengthen the alloy. The strength after heat treatment is about 50% to 100% higher than that of the annealed state; the high temperature strength is high, and it can work for a long time at a temperature of 400°C to 500°C, and its thermal stability is inferior to that of α alloy.
