Microstructural alterations in bearing steels under rolling contact fatigue
The formation of microstructural alterations in bearing steels under rolling contact fatigue (RCF) is systematically studied. A literature review summarizes current understanding in this field, leading to the key to the formation of these microstructural features being carbon redistribution as a …

Analytical and experimental investigation of microstructural alterations in bearing steel in rolling contact fatigue
… 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> <p>In the current work, an analytical as well as …

Mechanical Properties and Microstructure of Copper Alloys and Copper Alloy-Stainless Steel Laminates for Fusion Reactor High Heat Flux Applications
… bi-metallic panels. The joining processes caused microstructural alterations in the bond interfacial regions including: microporosity, new precipitate formation, existing precipitate morphology changes and interdiffusion of constituent elements.

Mechanisms of microstructural damage during rolling contact fatigue of bearing steels
… material undergoes rolling contact fatigue where microstructural damage manifests as dark-etching regions and white-etching areas, which display different properties from the surrounding region. The aim of this study is to identify the mechanisms for such damage and to suggest models that can …

Finite Element Modelling of Deep Zone Residual Stresses in Rolling Contact Bearing Elements.
… The evolved bearing material contains different microstructural features, termed as dark etching regions (DERs) and white etching bands (WEBs); visible after Nital etching. Intensive work has been carried out in the past few decades to define these microstructural changes along with mechanical …

Effects of the 1982-1983 El Niño mega event on bivalve mollusk biomineralization
… coast after the 1982-1983 El Niño, exhibit microstructural alterations in the shell in correlation with the sea surface temperature (SST) anomaly during the event. Common biomineral alterations include changes in the relative thickness of certain microstructural types and the loss of …

Carbide-free bainitic steels for wear and rolling contact fatigue resistant applications
… however, a straightforward relationship between microstructural features and the ultimate performance has yet to be found. It is believed that the retained austenite fraction, size and morphology are closely related to its mechanical stability, which is crucial in affecting its transformation to …

Evaluation of Cold Spray Process for Solid-State Welding
… CSWed samples show several benefits: negligible microstructural alterations, inhibition of phase transformations, and suppression of deleterious HAZ, they exhibit lower tensile strength and impact toughness than TIG-welded counterpart due to the presence of ubiquitous microvoids resulting from …

Denaturation of myofibrillar and sarcoplasmic proteins in pale, soft and exudative-like meat : effects on water-holding
… that the high temperature incubation induce microstructural alterations on the myosin head (S1) region, which may in turn have been related to the loss of water-holding. The roles of the denaturation of sarcoplasmic proteins and myofibrillar proteins were compared. Sarcoplasm not-incubated or …

Diffuse Damage Repair Mechanism in Bone
… that the spontaneous recovery of mechanical and microstructural alterations caused by Dif.Dx in bone requires deposition of Ca and Pi, but does not require the direct action of osteocytes. This repair process appears to resemble physicochemical remineralization like that occurring in enamel. …
