Originally published as Titanium alloy! Why do people think titanium alloy is awesome when they hear it? What kind of material is it? In some TV programs or on the Internet, we can often see how expensive it is to build an aircraft carrier. This is because the construction of an aircraft carrier involves many technical fields and related materials. Therefore, it is not enough to build an aircraft carrier with money, but also with a strong industrial base and material research and development capabilities. Photo: pixabay It has been reported that a rivet on the deck of an aircraft carrier can be exchanged for a car, which shows how expensive it is. This kind of rivet is not an ordinary rivet. It is a rivet made of titanium alloy material. This kind of expensive titanium alloy rivet is not all over the deck, and only in the place where fighter planes take off and land. Because fighter planes will spray high temperatures of more than 1000 degrees Celsius when taking off, which requires high temperature resistance of the deck, and the welding technology of high temperature resistant materials is not mature, so the assembly between decks needs to be completed by titanium alloy rivets. Titanium alloy is an alloy based on titanium with other elements as plasticity. What makes titanium so appealing is the quality it possesses. As a lightweight metal, titanium has the highest ratio of weight to strength of any element. It weighs 44% less than steel, but its mechanical strength is similar to that of steel and three times stronger than that of aluminum. Titanium is highly resistant to corrosion. Like aluminum, titanium is covered with a dense oxide film at room temperature. The non-toxic and non-magnetic titanium alloy is also suitable for industrial production; the liquid titanium can be dissolved with almost all metals, so that the liquid titanium can be alloyeis so valuable when titanium is not rare and there are so many reserves? This will involve metal smelting technology, titanium alloy smelting environment is extremely harsh, titanium in high temperature conditions, titanium plate gr7 , chemical activity is small, so smelting titanium alloy must be carried out at high temperature, in general, titanium alloy smelting temperature should be above 800 degrees Celsius, and also in a vacuum environment, this smelting environment is much higher tha Youtube "Titanium The STRONGEST METAL On Earth!"
