Effects of carbon content and sliding ratio on wear behavior of high-vanadium high-speed steel (HVHSS) under high-stress rolling–sliding contact

Mechanisms of Oxidation Degradation of Cr12 Roller Steel during Thermal Fatigue Tests

“…In some cases, carbides could oxidize faster than the matrix, depending on the local chemical composition, which complements the observations of Kim et al [34]. Large oxidation tongues in the present study contrast with oxidation studies [4,15,22,23,28,[34][35][36][37][38] and tribological tests [3,[9][10][11]14,16,25,26,33,35,[39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]. This is attributed to test conditions where thermal cycles play an important role in O diffusion and confirms the theory of Lao et al [27] that the condition under isothermal testing in the highly plastic deformed region during sliding wear is not comparable to the behavior during hot rolling.…”

“…On the other hand, the Cr content in primary carbides is slightly lower (42-50 wt. %) compared to the content in eutectic carbides (44)(45)(46)(47)(48)(49)(50)(51)(52) wt. %).…”

“…It is generally very complex, as temperature, time, environmental conditions and microstructure are intertwined [3,. The oxidation behavior of roller material at high temperatures was investigated by oxidation studies [4,15,22,23,28,[34][35][36][37][38], tribological tests [3,[9][10][11]14,16,25,26,33,35,[39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] and thermal fatigue tests [5,6,12,[29][30][31]. The tribological tests were performed with disc-on-disc tests [3,[9][10][11]…”

Theoretical and experimental investigation of thermal and oxidation behaviours of a high speed steel work roll during hot rolling

“…Since the end of last century, application of high speed steels (HSS) work rolls during hot rolling in industry has been increased quickly and made a breakthrough due to their excellent wear resistance, hardness, and high temperature service performances [33][34][35]. It has been reported that the HSS work rolls have about three times longer service life than the high chromium cast iron rolls [36].…”

Repetitive Impact Wear Behaviors of the Tempered 25Cr3Mo2NiWV Fe-Based Steel

“…Therefore, the researches on the effect of heat-treatment on the wear behavior are of importance to engineering. Heat treatment can change the mechanical properties of the steel and thus enhance their wear resistance [10][11][12][13][14]. To study the characteristics and the law of the impact wear failure of the test steel, it is tempered at different temperatures to produce various combinations of hardness and toughness.…”
