Overview


Haynes 25 is a cobalt-based superalloy, also known as L605 alloy. It has high strength and corrosion resistance, and is widely used in aerospace, oil and gas industry, medical equipment and chemical industry.

L-605 / Alloy 25 has excellent forming properties, capable of forging, hot working, or cold working, although its work hardening rate is very rapid, so frequent intermediate annealing is recommended for complex forming operations.When exposed at moderate temperatures for long periods of time, Haynes 25 exhibits the same room-temperature ductility loss as other superalloys, such as Alloy X or Alloy 625.Due to its long and extensive use, this alloy has been the subject of much research to determine its performance under a wide range of conditions, thus making it a very good characterization material, alloy L-605 has many applications in military and commercial gas turbine engine components such as rings, blades, and combustion chamber components, although for many modern engines, It has been largely replaced by alloy 188 or alloy 230.

The chemical composition of the alloy mainly includes cobalt, nickel, chromium, tungsten, iron and manganese, among which the addition of cobalt and chromium improves its oxidation resistance and corrosion resistance, while tungsten enhances its hardness and wear resistance. The alloy has moderate durability and creep strength below 815℃, excellent oxidation resistance below 1090℃, and satisfactory forming and welding properties.

Heat Treatment


Haynes 25 is a cobalt-based superalloy with excellent high temperature strength, creep resistance and corrosion resistance. In order to give full play to its performance advantages, heat treatment plays a crucial role in the alloy preparation process.

First, solution treatment is an important step in the Haynes 25 alloy. This process is usually carried out in the temperature range of 1180-1240 ° C and maintained for a period of time, so that the various elements in the alloy can be fully dissolved to form a single-phase solid solution. The alloy is then quickly cooled to room temperature to maintain a solid solution state. Solution treatment helps improve the plasticity and toughness of the material and prepares it for subsequent aging treatment.

Aging treatment is another key step in the heat treatment of Haynes 25 alloy. During this process, the alloy is heated to a temperature range of 600-760 ° C and kept there for several hours. By controlling the aging time and temperature, the microstructure and morphology of the precipitated phase of the alloy can be adjusted to optimize its mechanical properties and corrosion resistance. Aging treatment can help to form fine precipitates and enhance the strength and hardness of the alloy.

In addition, annealing treatment is also a way of heat treatment of Haynes 25 alloy. Annealing is the process of heating the alloy to the appropriate temperature and holding it for a period of time, and then slowly cooling it to room temperature. This treatment helps to reduce the stress inside the alloy, reduce problems such as cracks and oxidation, and improve the machinability and ductility of the material.
