A detailed investigation was conducted to analyze the damage mechanisms and microstructural evolution of high-manganese steel over multiple test cycles. Results reveal that the damage evolution of high-manganese steel under rolling-sliding contact follows a dynamic and cyclic pattern. During this process, the surface-hardened layer undergoes repeated deformation strengthening, eventually leading to spalling and resulting in a distinct cyclic damage progression. This progression is primarily driven by the interplay between deformation strengthening, which enhances wear resistance, and the gradual accumulation of fatigue damage. As the surface-hardened layer spalls, the wear resistance deteriorates, exposing fresh layers to subsequent deformation strengthening and fatigue damage accumulation. This cyclical process culminates in the repeated occurrence of spalling damage. These findings offer valuable insights into the damage mechanisms of high-manganese steel under complex service conditions, providing a solid foundation for future research in this area.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"568 ","pages":"Article 205994"},"PeriodicalIF":5.3,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sliding contact layers were observed to undergo plastic deformation due to the formation of certain transfer layers in the contact zone. It was shown that these layers contain more than 75 vol% FeO and also some initial phases. The transfer layers contained signs of melt formation. This phenomenon was described at a qualitative level. Melt appearance is conditioned by occurrence of a displacement current in FeO containing medium. This displacement current provided energy to the FeO ions for their transition to the melt. A low ductility of the doped initial phases caused an increase in wear intensity of the transfer layers. These effects were manifested due to a low ability of the material to relax the mechanical stresses in the contact zone of the alloy steels. This meant that a low ductility was among the main factors contributing to severe wear.

In contrast to most copper-based alloys, the tested material mainly consists of a single hexagonal close-packed phase with a negligible fraction of face-centered cubic phase. Electron backscatter diffraction was employed to examine plastic deformation induced by cavitation. This evaluation revealed a strong influence of the grain orientation on the local cavitation resistance. It is noticeable during the incubation stage that, while grain surfaces oriented nearly parallel to the basal plane exhibit visible deformation resulting from twinning, grains with surfaces oriented nearly parallel to prism planes show weak traces of plastic deformation and very low damage induced by cavitation. Additionally, grain boundaries located between grains subjected to large differences in deformation were found to be mostly resistant to cracking or void formation.

The maximum thickness of the deformation layer was about 40μm and accompanied by the fine grain and dense dislocation. Moreover, there were no significant micro defects in material surface layer after PUSR treatment. It was attributed to the effective material plastic deformation and grain refinement effects promoted by pulsed current assisted high-frequency ultrasonic vibration.

In this regard, the textured tools have been fabricated with various geometric texture shapes on tungsten carbide. The textures on the rake face of the tool have been fabricated by using various geometries such as discrete (dimple and hexagonal), continuous (sine wave), and a combination of discrete and continuous textures (mixed). Along with the textured shapes, the effect of variation in texture feature dimension (width or diameter- 40 μm, 80 μm, and 120 μm) on machining output has also been investigated. The developed tool has been employed for the machining of PH 13-8 Mo SS alloy to investigate the wear performance and derivative cutting phenomena. Upon investigation, it has been found that the combination of discrete and continuous textures i.e. mixed textured tool resulted in superior performance in terms of reduction of rake and flank wear. The experimental evidence demonstrates that a variation in the feature dimension of the texture has been a critical factor in the analysis of the derivative cutting phenomenon and the formation of build-up edge. It has been seen that machining operations performed at low speed with a discrete textured (hexagonal) tool having a feature dimension (width/diameter) of 40 μm have reduced the main cutting force up to 12 % as compared with the plain tool.
