Key words：material science; Advanced alloy material; super alloy; applications fields；

With the development of science and technology and the progress of human society, the rapid development of material science and technology has become an important support for social and economic development. Advanced alloy material is an important achievement in material science and technology, and its application field is very wide, it is one of the indispensable materials for modern industrial production.

Development history of advanced alloy materials:

Advanced alloy materials refer to metal materials with high strength, high-temperature stability, and high corrosion resistance. Its development can be traced back to the early 20th century when scientists in the United Kingdom and the United States began working on a superalloy, that is, a nickel-based alloy containing alloying elements such as chromium and molybdenum. This alloy material has excellent oxidation resistance in the thermal oxidation environment, so it is widely used in aviation, petroleum, chemical, and other high-temperature fields.

At the beginning of the 21st century, advanced alloy materials experienced a comprehensive reform and upgrade. The new advanced alloy materials use some new elements and preparation processes to make their comprehensive properties more excellent. For example, the new cast tungsten alloy material, its macro and microstructure is more uniform, has better corrosion resistance, and can meet the needs of aerospace, missiles, and other high-tech fields.

Advanced alloy materials have a wide range of applications in industrial production：

1. Aerospace: Aerospace is the main application field of advanced alloy materials. Advanced alloy materials can withstand high temperatures and high-pressure environments, improve the performance of aerospace engines and turbine engines, and reduce the weight of equipment.

2. Petroleum and chemicals: Petroleum and chemical production is another important area. High-temperature, high-pressure petroleum and chemical equipment requires the use of advanced alloy materials to resist corrosion and high-temperature gas erosion, making the equipment life longer, and reducing the cost of maintenance and replacement.

3. Medical: Advanced alloy materials are also used in medical device manufacturing. For example, titanium alloy materials can be used as artificial bone and tooth implant materials, have corrosion resistance, and good bio-compatibility, and human tissue is easy to fuse.

In short, the application field of advanced alloy materials is more and more extensive, and the application of the material is constantly promoted and improved, becoming an important support for modern industrial production.
