The stress state of wire drawing is the three-way main stress state of bidirectional compressive stress and tensile stress. Compared with the three-way main stress state of compressive stress, the drawn wire is easier to reach the plastic deformation state. The deformation state of drawing is the three-way main deformation state of bidirectional compression deformation and tensile deformation, which is unfavorable to the plasticity of metal materials and is easy to produce and expose surface defects. In the process of wire drawing, the trace deformation is limited by its safety factor, and the smaller the trace deformation is, the more the trace will be drawn. Therefore, multi-channel continuous high-speed drawing is often used in the production of wire.
1. Classification of titanium wire
Titanium can be divided into pure titanium and titanium alloy by whether it contains alloying elements, and titanium alloy can be divided into alpha titanium alloy and nearly alpha alloy, (alpha + beta) type alloy, nearly beta alloy and beta alloy according to the different composition and temperature structure. Titanium and titanium alloy according to the different properties and can be prepared different requirements for the use of silk. Titanium and titanium alloy wire products are generally hard state (Y) and annealed state (M).
2. Application of titanium wire
Titanium and titanium alloy with good corrosion resistance, higher than strength, nonmagnetic, high biocompatibility, on the impedance of the ultrasonic wave is small, high coefficient of acoustic, hydrogen storage, and good shape memory function and a series of excellent characteristics of has important use value, thus in aerospace, petrochemical industry, medical, automotive, construction, and sports leisure products produced important to use and many other fields. Titanium and titanium alloy wire as an important variety of titanium material series, no matter from the output, specifications, and applications have now made great progress. Titanium bar and titanium alloy material as the leader of metal materials have a series of other metal material incomparable excellent performance, so in recent years, the development is very fast, and has been rapidly and widely used in aerospace, military, and other high-tech fields. The United States, Russia, Japan, China and other countries in the world attach great importance to the research and development of titanium alloys, constantly develop new titanium alloy materials, expand the application of titanium and titanium alloys. Due to the deepening of research and the increase of product series, many titanium products, such as titanium wire products, have been increasingly entered into the field of various civil consumer goods.
