“…The SEM micrograph showed the lamellar structure of pearlite which was distinguished from the ferritic areas. Such microstructure was also reported in other works [2][3][4][5]. This microstructure characteristic could strongly govern the fatigue crack onset and propagation as shown in [5].…”

“…It was shown that unequal microstructure distributions in the wheel rim and wheel web strongly influenced its fatigue lifetime. Zhang et al [5] also showed that the incompatibility of plastic deformation of observed non-uniform microstructure including bainite promoted the formation of fatigue cracks. With respect to the effects of load types, fatigue limit and respective S-N curves of ER8 wheel steel under tension-shear multiaxial conditions were determined by Zhang et al [6].…”

“…Because it directly affects the safety of passengers, especially in the case of high-speed railway in which very high driving speeds are concerned. There have been researches with regard to different aspects of failures emerged in railway components [1][2][3][4][5][6]. In 1998, one of the very serious train accidents occurred in Germany was likely caused by a fatigue crack in only one wheel that finally led to fractures and disasters [1].…”

“…In general, the railway wheel grade ER8 specified by EN 13262 has been widely used in many high-speed trains. Such rail wheel steels mainly composed of a mixture of pearlitic and ferritic phases, which was sufficiently strong and showed high toughness [2][3][4][5][6]. Zheng et al [3] developed a wheel steel containing high amounts of Si and Mn and low content of Cr.…”

In this work, characteristics of fatigue crack growth in the Paris regime of the rail wheel steel grade ER8 were investigated. Experimental crack growth tests under different cyclic loads of a compact tension (CT) specimen and corresponding FE simulations were carried out. The extended FE method (XFEM) coupled with damage evolution based on the strain energy release rate or the Paris law was applied to describe the crack propagation mechanism in the tested CT samples. Hereby, the fatigue fracture model parameters were firstly determined from the experimental data. It was found that the predicted crack growth rates agreed well with the experimentally gathered results. Subsequently, fatigue crack propagations of the investigated wheel steel under varying load levels, load ratios and lengths of pre-crack were studied using the FE approach and the obtained crack growth characteristics were compared and discussed.

“…Pawlus et al [ 15 ] presented the method that allows obtaining the correct oil capacity in combination of the surface of elements. Various surface treatments are also used to create the desired properties of the cooperating surface layers [ 16 , 17 , 18 ]. Tests are also conducted in the scope of assessing the wear of elements in the abrasive mass [ 19 ].…”

This article presents the application of the ring-on-ring test to investigate some of the important factors affecting the abrasive and corrosion wear of a face seal used in the sugar industry. The test involves the sliding contact between two steel rings working in different conditions such as mechanic, abrasive, corrosive extortions and its combination. Rings were made of the C45 steel and the surface layers were modified by heat and thermochemical treatment such as normalizing, flame hardening, nitriding and chrome diffusion. Maximum wear of the sample after tests under mechanic, abrasive and corrosion extortion were obtained. For C45 steel without surface modification the biggest wear was obtained for mechanical, abrasive and corrosive extortion and equals 0.0138 g. This value was three times bigger than the result for the mechanical extortion and ten times than for the corrosive conditions. For individual research options the percentage increase or decrease in wear resistance in relation to the normalized surface layer was determined. In the corrosive extortion the highest increase (90%) of wear resistance was recorded for the chrome layer relative to normalizing sample. The main conclusion of the paper is that the wear effect caused by all factors—mechanical, abrasive and corrosive—is not a straight sum of values of wear.
