Effect of Hot Rolling Deformation on Microstructure and Mechanical Properties of High Titanium Wear-resistant Steel

    
    Introduction
    
    Hot rolling deformation is an important step in the production of high-titanium wear-resistant steel products. During the hot rolling deformation process, the microstructure of the steel undergoes significant changes as well as its mechanical properties. In this article, we will take a closer look at the effect of hot rolling deformation on the microstructure and mechanical properties of high-titanium wear-resistant steel. We will also discuss the post-hot rolling deformation treatments that can be applied to further modify and optimize the steel’s mechanical properties.
    
    Effect of Hot Rolling Deformation on Microstructure
    
    During the hot rolling process, the original as-cast microstructure of high-titanium wear-resistant steel is significantly changed. At elevated temperatures, the austenite grains tend to become elongated and the grains of carbides, inclusions and precipitates tend to become dispersed evenly throughout the steel matrix. This results in a highly homogeneous microstructure with a fine-grained distribution.
    
    The presence of multiple elements in high-titanium wear-resistant steel will form various kinds of compound precipitates during the hot rolling process. These precipitation products tend to be more stable and less affected by the redox action in the hot rolling process than their elemental precursors, resulting in a microstructure with improved wear-resistant properties as well as an improved strength-to-ductility balance. Furthermore, the presence of multiple phases with different properties in the microstructure further improves the wear-resistance of the steel.
    
    Effect of Hot Rolling Deformation on Mechanical Properties
    
    Hot rolling deformation is an important step in the production process of high-titanium wear-resistant steel. After the hot rolling deformation process, the steel’s mechanical properties are significantly improved. The uniform microstructure resulting from the hot rolling process further enhances the mechanical properties of the steel. The mechanical properties of the steel after hot rolling deformation include increased ultimate tensile strength, yield strength, and toughness.
    
    The hot rolling process also reduces the amount of material distortion present in the steel. This results in improved formability and ductility of the steel allowing it to be cold-formed with fewer difficulties. Furthermore, the hot rolling process also improves the impact performance of the steel making it more suitable for applications that require high impact resistance. It also reduces the steel’s susceptibility to thermal shocks and increases its wear-resistance.
    
    Conclusion
    
    Hot rolling deformation is an essential step in the production of high-titanium wear-resistant steel. Through the hot rolling process, the microstructure of the steel undergoes significant changes which improves its mechanical properties. Not only does the hot rolling process change the microstructure, but it also improves the steel’s formability and ductility, as well as its impact and wear-resistance properties. Finally, post-hot rolling deformation treatments can further modify and optimize the mechanical properties of high-titanium wear-resistant steel.
