To study the influence of indentation on the fatigue strength of untreated and carbonitrided specimens of S38C steel, the fatigue limit of specimens with and without indentations was tested. Fracture surfaces were observed using scanning electron mic

This work addresses the tension-shear multiaxial fatigue behavior of ER8 medium carbon steel, commonly used for the high-speed railway wheel. Making use of high-frequency fatigue tests with different applied loading angles, namely 0° (uniaxial), 30

This study aims at determining the influence of laminar plasma quenching (LPQ) on the rolling contact fatigue (RCF) behaviour under water condition of high-speed railway wheel steel. The wheel and rail test rollers were treated by LPQ with different

A novel heat treatment process combined cyclic quenching (CQ) with austenite reversion treatment (ART) is proposed to obtain high strength–ductility and high-impact toughness combination in Fe-0.18C-8.92Mn-3.43Al (in mass%) steel. The process refer

Optimizing supports for microorganisms is required for bioreactors. Carbon fibres (CF) were employed as supports for microorganisms. To optimize CF supports for immobilizing bacterial cells, we used methods of nitric acid oxidation and calcium ion co

A semisolid slurry of Al-Zn-Mg-Cu alloy was prepared by adding 0.1 wt.% Al-5Ti–1 B master alloy and rheo-diecast with different injection velocities. The average size of the primary α-Al particles in the rheo-diecast parts decreased and its shape

Foreign object damage (FOD) introduced in service, indentations, and nicks encountered during maintenance are typical defects leading to pre-scrap of high-speed railway axles. A comprehensive assessment of the influence of these defects on the struct

A series of characterization tests were performed to elucidate the high-cycle fatigue behavior in a type of steel often used in high-speed railway wheel rims. The specimens were cyclically-loaded with a constant stress amplitude of 370 MPa at the str
