一、引言 钛具有重量轻、强度高、高温性能和低温性能良好、优异的耐蚀性能等优点,最初用于飞机制造工业,后又用于火箭、导弹、造船、武器、冶金、化学和石油等工业。 但与钛的应用形成一对矛盾的不可忽视的另一方面是钛的价格目前太贵,并造成了互为因果的关系,即:为了扩大钛的应用必须降低钛材的价格,同时为了降低钛材的价格必须扩大其应用。
I. INTRODUCTION Titanium has the advantages of light weight, high strength, good high-temperature performance and low-temperature performance, excellent corrosion resistance and other advantages. It was initially used in the aircraft manufacturing industry and later used in rockets, missiles, shipbuilding, weapons, metallurgy, chemistry and petroleum Other industries. On the other hand, the price of titanium is too expensive at present because it forms a contradiction with the application of titanium, which leads to the mutual causality. In order to expand the application of titanium, the price of titanium must be reduced, meanwhile, in order to reduce the price of titanium, Titanium prices must expand its application.
