The current application and development status of iron-based materials at home and aboard was summarized

focusing on corrosion resistance of molten aluminum. The approaches and related mechanisms to improve the corrosion resistance of molten aluminum were described from the aspects of alloy elements

surface modifications and thermal treatments.Finally

based on the existing technical achievements of the researchers

it is planned to propose future design

improvement thoughts and key research directions for developing a new type of high-quality and inexpensive iron-based materials resistant to corrosion in molten aluminum or significantly improving the corrosion resistance of existing materials.
