Problems solved by technology

Due to the high melting point of some β-phase stable elements, it is difficult to melt, such as vanadium (melting point 1890 ° C), molybdenum (melting point 2610 ° C), chromium (melting point 1907 ° C), tantalum (melting point 2996 ° C), tungsten (melting point 3380 ° C), these The use of high melting point raw materials will inevitably increase the manufacturing cost of titanium alloys
In addition, according to a rough market survey, the prices of commonly used alloying elements are high, for example, vanadium (about 3,000 yuan / KG), molybdenum (about 500 yuan / KG), chromium (about 650 yuan / KG), tantalum (about 4,800 yuan / KG) KG), tungsten (about 500 yuan / KG)
Combining the above factors, it is not conducive to the large-scale application of titanium alloys

example 1

[0017] 88.5 grams of pure titanium wire and 11.5 grams of iron-carbon alloy with a carbon content of 0.45% are used for smelting in a non-consumable vacuum electric arc furnace. The background vacuum of the electric arc furnace during smelting is higher than 2.0×10 -2 Pa, the working current of the arc welding power supply is 400A, and the working voltage is 20V. After the alloy is smelted into a whole for the first time, it is turned over in the crucible for the second smelting, and this is repeated for a total of 8 times. After the alloy is smelted, an alloy sample with a size of φ5×10mm is cut from the alloy ingot by wire electric discharge cutting, and the mechanical properties are tested by a compression mechanical testing machine with an extensometer. The structure is shown in Table 1. The microstructure of the alloy was observed by optical microscope and scanning electron microscope. From figure 1 The compressive mechanical performance test of the as-cast alloy shows...

example 2

[0019] 88.5 grams of pure titanium wire and 11.5 grams of iron-carbon alloy with a carbon content of 0.56% are used for smelting in a non-consumable vacuum electric arc furnace. The background vacuum of the electric arc furnace during smelting is higher than 2.0×10 -2 Pa, the working current of the arc welding power supply is 420A, and the working voltage is 30V. After the alloy is smelted into a whole for the first time, it is turned over in the crucible for the second smelting, and this is repeated for a total of 8 times.

[0020] After the alloy has been repeatedly smelted evenly, alloy samples with length, width and height of 40, 40, and 15 are cut from the alloy ingot by wire electric discharge cutting, and rolled at 900 °C for multiple passes, and the deformation of each pass is controlled at Within 10%, the total deformation is more than 60%. After rolling, the alloy is cooled to room temperature by water quenching or air cooling. The alloy plate was cut into tensile ...

Abstract

Disclosed is titanium-iron-carbon alloy with low cost and high strength. The titanium-iron-carbon alloy is characterized by comprising, by mass, 11%-12% of Fe, 0.03%-0.07% of C, the balance Ti and inevitable impurities. According to the titanium-iron-carbon alloy, a titanium alloy system serves as an object; the two elements of titanium and iron serve as a main alloy body; the titanium alloy with high strength and ductility is obtained by adding trace carbon element. The titanium alloy adopting the matching ratio is not only easy to smelt, but also low in cost.

Description

technical field [0001] The invention relates to the fields of material science and non-ferrous metals and their alloys, especially titanium alloys. Background technique [0002] Titanium is a medium-low density metal (its density is 4.5), has high specific strength, good medium temperature performance, non-magnetic, strong corrosion resistance, good welding performance, and is an excellent metal structure material. 100 Over the past years, it has increasingly occupied a leading position in high-tech fields such as aviation, aerospace, ships, nuclear power, weaponry, oil exploration and biomedical materials, and its main development trend is high performance and low cost.
