What Are Disadvantages of 90WMoNiFe High-Entropy Alloy?

The disadvantages of 90WMoNiFe high-entropy alloy may include the following aspects:

high cost

Because tungsten, molybdenum, nickel, and iron are all relatively rare metal elements, 90WMoNiFe high-entropy alloys are generally more expensive to produce. This may limit its application in certain areas, especially where cost requirements are high.

Processing difficulty

Due to the high hardness and strength of tungsten-molybdenum-iron high-entropy alloy, its processing and forming are relatively difficult. This may require special processing equipment and processes, thereby increasing production costs and processing cycles.

Low thermal conductivity

Although 90WMoNiFe high-entropy alloy has good stability at high temperatures, its thermal conductivity is relatively low. This may result in limited performance of the alloy in certain applications where efficient heat dissipation is required.

Sensitivity to the environment

In certain specific environments, such as strong acid, strong alkali or high-temperature oxidizing atmosphere, 90WMoNiFe high-entropy alloy may corrode or oxidize. This may affect its service life and performance stability.

These shortcomings do not mean that 90WMoNiFe high-entropy alloys have no application value or prospects. Through reasonable composition design, process optimization and surface treatment, these shortcomings can be improved to a certain extent and the application fields of the alloy can be expanded. In addition, with the continuous development and progress of science and technology, new methods and technologies may emerge in the future to further improve the performance of tungsten-molybdenum-iron high-entropy alloys.
