The difference between titanium and titanium alloy plates

Titanium is a refractory metal of a light metal, a density of 4.5 g / cm3, 57% only of iron. Strength titanium alloy with high strength comparable to steel, but also has good heat resistance and low temperature performance, long-term work at certain alloy between 450 ℃ ~ 550 ℃ and minus 250 ℃. Titanium has good salt tolerance classes, the ability to seawater and nitric acid corrosion, Ti-30M alloy is resistant to high concentrations of hydrochloric acid and sulfuric acid corrosion. These advantages of titanium, grade 2 titanium wire deserved to be called a "space" metal, "Ocean" and the following metal steel, aluminum metal after the third and so on.
Titanium and titanium alloy material at room temperature forming plant, due to the forming force, a small amount of deformation limit and great resilience, which gave the manufacturing process brings a lot of difficulties, especially resilient, so that the hand injury the entire amount of labor large batch production can not meet the requirements.
The hot press forming is generally used in the manufacture of seamless titanium tube metal pieces and effective process methods, this method can be at room temperature (or heated state F) molded item, reheat Shaping: pull the materials can be directly used to form a heat and Hot school shape. Whether it is hot forming and heat were collapsed to form the school principle creep and relaxation of effort.
Thermoforming mainly take advantage of the softening and creep properties of the material in a heated state, and to improve the plastic to reduce and improve the molding forming force than to avoid cracking, but also reduce some rebound. Thermal Shaping mainly using the principle of stress relaxation in the heated state, in order to eliminate the springback, solve the problem of the precision of the parts due to the problems caused by springback.
In order to understand the mechanism of heat and hot forming shaped school must master creep and stress relaxation of principle. Month away, but this rationale Mrs perish only the right to development, but more with ten design chemical, atomic, gas and gas turbine boil, supersonic aircraft, spacecraft and other buildings of the structure of the product.
Titanium and its alloys as popular as the reason for the absence of aluminum, mainly due to high prices. To reduce costs, the new process for anyone conducting research abroad titanium alloys, such as electrolysis and direct reduction method, once the breakthrough will significantly decrease the cost of titanium sponge, will greatly stimulate the development of titanium grade 2 industry, we can only trace of such studies , can ensure China's titanium industry invincible. Besides the lack of significant capital investment in the processing of titanium and its alloys and titanium forming technology processing technology and applications, thus limiting the vigorous development of titanium industry.
