In the process of cutting titanium, the precautions are

In the process of cutting titanium, the precautions are:
(1) Due to the small elastic modulus of titanium investment casting, the deformation of the workpiece clamped in the processing of large deformation and stress, will reduce the machining accuracy of the workpiece; workpiece clamping force installation should not be too large, increase aid support when necessary.
(2) If using liquid hydrogen cutting, the cutting process will decompose at high temperatures to release hydrogen embrittlement caused by absorption of titanium; it may cause high temperature titanium stress corrosion cracking.
(3) the use of cutting fluid chlorides are also likely to break down or volatile toxic gases, the use of security measures should be taken, otherwise it should not be used; after cutting should be timely and chlorine-free cleaning agent thoroughly cleaned parts, remove residual chlorine thereof.
(4) prohibits the use of lead or zinc-based alloy production workers, fixture and titanium contact, copper, tin, cadmium and its alloys are also prohibited.
(5) All workers, fixtures or other devices must be in contact with the titanium tubing clean; titanium parts cleaned off, to prevent contamination of grease or fingerprints, or after the salt may cause stress corrosion.

Titanium uses editor：
Titanium has a high strength and density and small, good mechanical properties, good toughness and corrosion resistance. In addition, poor process performance. Titanium tubing, machining difficulties in thermal processing, and very easy to absorb carbon hydrogen nitrogen and other impurities. There are poor abrasion resistance, complex production process. Titanium industrial production was started in 1948. Require the development of the aviation industry, the titanium industry with an average annual growth rate of about 8% of the development. World titanium alloy production reached 40,000 tons, nearly 30 kinds of titanium alloys. The most widely used titanium alloy is Ti-6Al-4V, Ti-5Al-2.5Sn and commercially pure titanium.
Titanium is mainly used for the production of aircraft engine compressor components, followed by structure rockets, missiles and high-speed aircraft. The mid-1960s, titanium and its alloys have been in general industrial applications, electrodes for electrolysis industry production, power plant condensers, oil refining and desalination heater and environmental pollution control devices. Titanium wire mesh  have become a corrosion resistant structural materials. In addition, for the production of hydrogen storage materials and shape memory alloys.
