在不远的将来,钛有可能取代钢铁,成为继铜、铁、铝之后,使用最广泛的金属。钛是一种白色金属,具有比重小、强度高、抗腐蚀等优良性能。钛合金在-100℃～540℃的环境下,各项性能保持不变。这种优良的耐冷耐热特性是其它金属材料望尘莫及的。目前钛产量的70％左右用于制造飞机、火箭、导弹、坦克、潜艇等现代化武器。由于超音速喷气式飞机的铝合金只能承受一定的温度,当飞行速度大于2～3倍音速时便不能胜任,这就是所谓的“热障”,由于钛合金的出现,人类克服“热
In the near future, titanium may replace steel and become the most widely used metal after copper, iron and aluminum. Titanium is a white metal with excellent properties such as small specific gravity, high strength, and corrosion resistance. Titanium alloys maintain their properties at -100°C to 540°C. This excellent resistance to cold and heat is beyond the reach of other metal materials. At present, about 70% of titanium production is used to manufacture modern weapons such as aircrafts, rockets, missiles, tanks, and submarines. Because the supersonic jet aircraft’s aluminum alloy can only withstand a certain temperature, when the flying speed is greater than 2 to 3 times the speed of sound, it is incompetent. This is the so-called “thermal barrier”. Due to the appearance of titanium alloy, humans overcome the “heat.”
