Dezvoltare Istorie Titan Aliaje

Titanium is an important structural metal developed in the 1950s, and titanium alloys are widely used in various fields due to their high strength, good corrosion resistance, and high heat resistance. Many countries around the world have recognized the importance of titanium alloy materials and have conducted research and development on them, which have been applied in practice.
The first practical titan alloy was the Ti-6Al-4V alloy develop in the United States in 1954. Due to its good heat resistance, strength, plasticity, durity, formability, weldability, corrosion resistance, and biocompatibility, it has become the flagship alloy in the titanium alloy industry, accounting for 75 percent to 85 percent of all titanium alloys. Multe altele titan aliaje poate fi văzut as modificări of Ti-6Al{-4V aliaj.
In the anii 1950 și anii 1960, the main focus was on dezvoltare temperatură înaltă titan aliaje pentru aviație motoare și structural titan aliaje pentru aeronave corpuri. In the anii 1970, a lot de rezistent la coroziune titan aliaje was dezvoltat, and since the 1980s, rezistent la coroziune titan aliaje și high-resistance titanium alloys and high-strength titanium alloys have been further developat. Utilizarea temperatura de rezistent la căldură titan aliaje has crescut de la 400 grad in the anii 1950 la 600-650} grad in the anii 1990. The emergence of A2 (Ti3Al) and r (TiAl) based alloys has led to the advancement of titanium from the cold end (ventilator and compresor) of the engine to the hot end (turbine) of the engine in its usage area. Structural titan aliaje sunt în curs de dezvoltare spre înalt rezistență, ridicat plasticitate, ridicat rezistență, ridicat duritate, înalt modul și ridicat deteriorare toleranță.
In addition, since the 1970s, shape memory alloys such as Ti Ni, Ti Ni Fe, and Ti Ni Nb have also emerged and have been increasingly widely used in engineering.
There are sute de titan aliaje dezvoltate în the world, with 20-30} most famous alloys, such as Ti-6Al-4V, Ti-5Al{-2.5Sn, Ti-2Al{-2.5Zr, Ti-32Mo, Ti Mo Ni, Ti Pd, SP-700, Ti{{11}% 7d, Ti-10-5-3, Ti-1023, BT9, BT20, IMI829, IMI834, etc. [2,4].
According to relevant statistical data, the amount of titanium used in China's chemical industry reached 25000 tons in 2012, a decrease from 2011. This is the first time since 2009 that China's chemical titanium market has experienced negative growth. In recent years, the chemical industry has always been the largest user of titanium processing materials, with its usage accounting for over 50 percent of the total usage of titanium materials, reaching a high of 55 percent in 2011. However, as the economy enters a downturn, the chemical industry not only significantly reduces new projects, but also faces industrial restructuring, with some new production capacity for products being controlled and outdated production capacity gradually being phased out. Due to this impact, the decline in the usage of titanium processing materials has become a natural trend. Prior to this, industry insiders predicted that the amount of titanium used in the chemical industry would peak between 2013 and 2015. From the current market performance, the overall economic weakness in 2012 may have led to an earlier recession period for chemical titanium.
