Problems solved by technology

Once a titanium fire occurs, it develops fissionally in the environment of high temperature, high pressure and high speed airflow. The continuous burning time of compressor parts does not exceed 20s. It is difficult to take effective fire extinguishing measures, resulting in blade burnout, casing burnout, and even burnt out whole engine

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a titanium alloy. Background technique [0002] Titanium looks like steel, with a melting point of 1672°C, which is a refractory metal. The density of titanium is 4.51 grams / cm 3 , less than 60% of steel, is the metal with the lowest density among refractory metals. Among the commonly used metal elements, titanium is the fourth metal after iron, magnesium and aluminum. After alloying, titanium alloy has the characteristics of low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic and non-magnetic, weldable, good biocompatibility, and strong surface decoration. Titanium alloy is an important structural metal developed in the 1950s. It is widely used in aviation, aerospace, chemical industry, petroleum, electric power, medical treatment, construction, sporting goods and other fields. Obviously, titanium alloy has strong vitality as a ...
