Analytical and experimental investigation of microstructural alterations in bearing steel in rolling contact fatigue
… (RCF) is one the most common failure modes in bearings. RCF is usually associated with particular microstructural alterations. Such alterations (i.e. white etching cracks, butterflies, etc.) which lead to RCF failure are known to be among the most concerning matters to bearing industry.</p> …

Analysis of the Tribological Behaviour of Stainless and Ball Bearing Steels Sliding in the Presence of Sulphur Extreme-Pressure Additives
… The tribological behaviour of stainless and ball bearing steel were studied under extreme pressure and/or anti-wear lubrication conditions in the presence of sulphur and sulphur containing additives, in order to compare the wear behaviour of the AISI 420 stainless steel with the SAE 52100 steel, …

Hydrogen trapping in bearing steels: mechanisms and alloy design
… rich environment, applications such as rolling bearings display a significant decrease in alloy strength and accelerated failure due to rolling contact fatigue. In spite of these problems being well recognised, there is little understanding as to which mechanisms are present in hydrogen induced …

Nanostructural Evolution of Hard Turning Layers in Carburized Steel
… bulk material properties are determined by the steel making, forming and the heat treatment; the near surface material properties are altered during final material removal processes such as hard turning or grinding. Therefore, the ability to optimize, modulate and predict the near surface …

Hydrogen embrittlement resistance in advanced high strength: vanadium bearing and TRIP-assisted steels
Advanced high strength steels undergo a series of microstructural transitions associated with damage, these lead to failure especially when hydrogen enters the lattice and gets trapped in defects. It is desired to design advanced steels highly resistant to hydrogen embrittlement (HE), while …

Understanding the Stability of Retained Austenite in High-Carbon Steels: Modelling and Alloy Design
In high-carbon steels, the austenite-to-martensite transformation under applied stress initiates at a critical value, contrary to low-carbon steels where the transformation occurs at the early stages of deformation. There are few models that account for the delayed transformation, because previous …
