Abstract
To further reduce the density of light steel and improve its wear resistance, a light-weight wear-resistant steel containing beryllium was developed. In this study, the effects of different loads and Be content on the wear mechanism and microstructure of beryllium steel under slow cooling were evaluated. The results show that the load increases, friction loss and deformation on the surface of each sample increases. Oxidative wear and fatigue wear dominate. As the Be content increases, oxidative wear dominates and wear amount decreases. Beryllium compounds exist and are widely distributed on the surface of the matrix, resulting in an increase in hardness. The new strengthening method of Be−Fe phase provides a possibility for the wear resistance application of ultra-light steel.
