Titanium Aluminum Alloy Preparation & Applications

As early as the 1970s, titanium aluminum alloy was known as a promising high-temperature resistant material. It has high strength and good high-temperature resistance, but due to its low ductility and poor workability, it has not been mass-produced and used in the industry.

In order to improve the high-temperature resistance of Ti-Al alloys, a third element is usually added to form a ternary alloy. The influence of the third alloy on material properties is very obvious. It can make the titanium aluminum alloy have good ductility at lower working temperatures. The third commonly used alloy element is chromium, molybdenum, manganese, niobium, vanadium, and copper. 

In recent years, research and experiment on the titanium-aluminum alloy have achieved good results, and there have been titanium-aluminum alloy varieties that can be mass-produced.

Preparation and Processing Technology of the Titanium Aluminum Alloy

The preparation and processing technology of Ti-Al alloy mainly includes the following:

1. Ingot Metallurgy Technology

The titanium-aluminum alloy prepared by this method has problems such as segregation of ingot composition and uneven structure.

2. Rapid Condensation Technology

The Ti-Al alloy powder prepared by this method has a stable chemical composition and good process performance, but with the change in heat treatment temperature, the microstructure and hardness of the powder will change accordingly.

3. Composite Material Technology

The titanium-aluminum alloy prepared by this method shows good strengthening performance, but problems such as lateral performance and environmental resistance still need to be resolved.

4. Powder Metallurgy Technology

This method can prepare evenly structured and fine parts, and can realize the near-net shape of the parts, and can effectively solve the problem of difficult processing and forming of Ti-Al intermetallic compound alloys.

The Applications of the Titanium Aluminum Alloy

It can be said that the automobile manufacturing field began to use Ti-Al alloy materials in large quantities at the earliest. For example, Japan’s Mitsubishi Automobile Company had used Ti-Al alloy materials to produce superchargers for automobile engines since 2000. 

A large number of practical applications, field tests, and engine performance tests show that the use of Ti-Al alloy parts optimizes the performance of automobile engines and has the advantage of energy-saving.

The application of Ti-Al alloy in the aerospace industry also has broad development prospects and has now become the material of choice for advanced military aircraft engine high-pressure compressors and low-pressure turbine blades.
