Products Description
The nominal composition of TC11 titanium alloy is Ti-6.5Al-3.5Mo-1.5Zr-0.3Si, which is an α-β type heat-resistant titanium alloy. TC11 titanium alloy rod is mainly used in dry aircraft engine compressor discs, blades, drums and aircraft structural parts. With the continuous development of aviation technology, the main materials for manufacturing aircraft engines, high-pressure compressor discs and blades are also used to manufacture important load-bearing parts on aircraft. It can also be made into special-shaped castings. The working conditions of the parts are that they can be used for 500 hours below 500℃, 100 hours below 550℃ and 1000 hours below 450℃ in the annealed state, and can be used for parts working for 100 hours below 500℃ and parts working once below 700℃ in the strengthened state.

TC11 titanium rod inspection method:
1. Ultrasonic flaw detection shall comply with the provisions of GB/T5193, and its acceptance level shall be agreed upon by both parties. Mainly detect whether there are cracks inside the titanium rod, etc.
2. Macrostructure: The transverse macrostructure of the rod should not have cracks, shrinkage tails, pores, metal or non-metal inclusions, and metallurgical defects that affect the use.
3. Microstructure: When the demander has requirements for the microstructure of the rod, it shall be determined by negotiation between the supply and demand parties and indicated in the contract
4. Appearance inspection: The surface of the rod is allowed to have minor scratches, indentations, pits and wrinkles that are not greater than half of the allowable deviation of the diameter or thickness.
The test methods of TC11 titanium bars include:
1. Chemical composition analysis: It is carried out in accordance with GB/T4698 standard.
2. Room temperature tensile test: in accordance with GB/T228 standard.
3. High temperature tensile test: in accordance with GB/T4338 standard.
4. High temperature endurance test: in accordance with GB/T2039 standard.
5. Ultrasonic flaw detection: in accordance with GB/T5193 standard.
