DESCRIPTION
Ferrovanadium improves the fatigue strength of steel by reducing crack initiation and propagation. The presence of fine grains and vanadium-rich phases inhibits the growth of cracks, preventing them from reaching critical lengths that could lead to failure. This increased resistance to crack growth significantly enhances the fatigue strength of the steel.
Furthermore, the formation of vanadium carbides in the steel matrix due to ferrovanadium addition contributes to improved fatigue strength. These carbides act as barriers to dislocation movement, which helps to prevent crack initiation and reduce the likelihood of fatigue failure.
By enhancing the fatigue strength of steel, ferrovanadium enables the development of materials that can withstand cyclic loading and perform reliably over extended periods, making it ideal for applications in industries such as automotive, aerospace, and structural engineering.
