Abstract X-ray diffraction has been widely used in measuring surface residual stresses. A drawback of the conventional d ~ sin 2 ψ method is increased uncertainty arising from splitting when a significant shear stress co-exists with normal stress. In particular, can only be applied to measure while leaving unknown. this paper, we propose new approach make simultaneous measurement both and Theoretical development described detail, which includes two linear regressions, $$\frac{{d}_{\psi }+...
In a rail track structure, turnout is used as transition between straight and branching rails therefore withstands complex dynamic rolling impact loading. This paper reports comprehensive failure investigation of railway off-track made from Hadfield austenitic cast steel. The worn was examined using optical microscopy, scanning electron micro-hardness, quantitative X-ray diffraction analyses. A ball-on-disc sliding wear test also applied to evaluate the work-hardening on property. exhibited...
Abstract Braking discs play an important role for the safety of vehicles whereas severe frictional contacts in repeated braking operations result thermal and tribological failures. This paper reports comprehensive surface subsurface analyses a used grey cast iron disc to investigate its failure mechanisms as well related microstructure evolution. Thermal cracking, spalling wear tribo-oxidation have been found contribute failure. The flake-type graphite triggered propagation internal...
Grown by reactive unbalanced magnetron sputtering in a mixed N2 and CH4 gaseous medium, heterogeneous nanocomposite coatings the Ti–Al–V–N–C system show extraordinarily excellent tribological performance of coated machining tools. Using analytical high-resolution TEM, EELS, FEG-SEM, XRD, Raman spectroscopy, this paper reports detailed structural chemical characterization grown at various : ratios. Meanwhile, mechanical properties were also measured, including hardness, Young's modulus,...
