Residual Stress in Wheels: Comparison of Neutron Diffraction and Ultrasonic Methods, with Trends in RCF [PDF]

, 2014
The critical damage mechanism on many GB passenger train wheels is Rolling Contact Fatigue (RCF) cracking in the rim. Evidence from field observations suggests that RCF damage occurs much more quickly as the wheelsets near the end of their life.

Residual stress field of HIPed silicon nitride rolling elements [PDF]

, 2002
The residual stress field of HIPed Si3N4 rolling elements were studied. Two kinds of HIPed Si3N4 ball blanks self-finished at different nominal lapping loads ranging from 1.3 to 10.87 kgf/ball and four kinds of commercially finished 1/2 in (12.7 mm ...

Effect of homogenization annealing on internal residual stress distribution and texture in ME21 magnesium alloy extruded plates

Journal of Magnesium and Alloys, 2019
The distribution of residual stresses through thickness of 5 mm-thick ME21 magnesium alloy extruded plates was analyzed non-destructively using short-wavelength X-ray diffraction (SWXRD), and the effect of homogenization annealing before extrusion on the

Impact of Electrolyte Formulation on the Phase Behavior and Interphase Formation of Sb/Graphite Electrodes for K‐Ion Batteries

Advanced Science
High capacity alloy‐type materials are attractive anodes for potassium‐ion batteries yet their practical use is hampered by extreme volumetric expansion that causes mechanical instability and rapid capacity fading.
