The different generations of bearing steel are designed to withstand high temperatures,
quick speeds, and heavy loads and meet the requirements of aviation, aerospace, and …

In this work, the effect of ion nitriding on the properties of high carbon chromium bearing
steel containing rare earth (RE) elements was studied by micro-Vickers hardness, tensile …

In this study, the trade-off between strength and low-temperature toughness of high-strength
low-alloy (HSLA) structural steel was solved by adding trace Ce, which increased yield …

The effect of rare earth Y on the microstructure and properties of high-carbon chromium
bearing steel in different heat treatment processes has been studied. The microstructure and …

The evolution of non-metallic inclusions (NMIs) in the industrial production process of
42CrMo4 medium carbon alloy steel was analyzed by 3D-XRM and 2D methods. The results …

The state of austenite grains has an essential role in the microstructure transformation and
mechanical properties of alloy steel during heat treatment or subsequent hot working. The …

In view of the phenomenon that irregular inclusions are easy to use as crack sources, rare
earth H13 steel with different gradients is designed. The results showed that ellipsoidal rare …

M50NiL bearing steel is widely used in the aerospace field because of its excellent
properties. δ ferrite would affect the impact toughness of steel, but there is little research on it …

Due to the strong reducibility and chemical activity of rare earths, the diffusion behavior and
secondary oxidation of rare earths in the steel liquid will also have a significant impact on …

The effects of Ce on inclusions and the primary carbide network of AISI 440C bearing steel
are experimentally and theoretically investigated. Adding Ce improves the cleanliness and …
