However, magnesium alloys face challenges like poor wear resistance and mechanical strength. To overcome these limitations, a promising approach involves developing heterogeneous hybrid microstructures through reinforcement addition and microstructural engineering. This study focuses on the tribological performance of a newly developed <em>in-situ</em> sub-micron sized TiB₂/ZE41 composite under various microstructural conditions, comparing it to the unreinforced ZE41 Mg alloy. Wear experiments were conducted using a pin-on-disc tribometer under normal loads of 10, 20, 40, and 60 N at a sliding velocity of 1 m/s. Scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) was used to analyze the worn surfaces in order to identify damage types and surface distortions. By correlating worn surface microstructures with test parameters, predominant wear mechanisms for each material condition under specific loads were determined. Results consistently showed that the presence of <em>in-situ</em> TiB₂ reinforcements, β-phase, and rare-earth precipitates enhanced wear resistance regardless of the load conditions. Additionally, the study established a scientific understanding of the wear behavior of ZE41 Mg alloy, with and without <em>in-situ</em> TiB₂ particles and precipitates, through analysis of dominant wear mechanisms, wear-induced subsurface deformation mechanisms, kernel average misorientation, grain orientation spread, and microhardness evaluation.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"560 ","pages":"Article 205609"},"PeriodicalIF":5.3,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531158","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}

In cutting processes, tool-life testing procedures are defined by ISO standards. These standards give the guidelines to perform tool-life testing in terms of workpiece material, tool geometry, tool material, cutting fluid, tool wear assessment, and tool-life evaluation. For determining the useful tool-life, the standards recommend running several tool-life tests at constant cutting speed till reaching a specified value of tool wear, as defined by the selected tool-life criterion. But, in industrial applications, the approach is different. The same tool is often used to make different geometrical features on the same component using different process parameters, depending on the desired geometry and surface quality. Therefore, it is possible to state that the tool accumulates wear over the working time under different cutting conditions. In other words, the tool is subjected to cumulative tool wear. This paper aims to deepen the knowledge about cumulative tool wear, which means the tool wear generated by a combination of different process parameters. An innovative experimental procedure is proposed to determine the useful tool-life when machining a part with the same tool at different process parameters. Cumulative tool flank wear tests were performed on AISI 1045 samples by changing the cutting speed, keeping the other cutting parameters constant. The experimental cumulative flank wear evolution was compared with the theoretical one. Four different machining cycles were tested to simulate different industrial cases.

The key prerequisite to fully exploit its efficacy lies in ensuring that the EDC exhibits appropriate deformation. In this work, we propose aperture processing in different regions of the EDC to optimize its deformation area and improve the interfaces tribological behavior. The EDC was mounted on the rear side of the friction block, and experiments on friction braking were carried out using a custom-built simulation rig designed to test the braking performance. This enables the study of the friction and wear characteristics across different EDC conditions, along with the characteristics related to friction-induced vibration and noise (FIVN). A finite element model (FEM) was developed reflecting the primary structure of the test rig, with initial surface wear simulations conducted on the blocks to achieve wear surfaces approximating the experimental outcomes. Implicit dynamic analysis (IDA) was then conducted based on this foundation. The enhancement in tribological behavior through optimizing the EDC deformation area was analyzed by integrating test results with finite element analysis (FEA) findings. The results indicate that aperture processing in different regions of the EDC has no significant effect on its dynamic response but can significantly alter its deformation characteristics, thereby achieving optimization of the EDC deformation. Adjusting apertures in various sections of the EDC markedly affects the development pattern and strength of FIVN. However, this approach maintains the fundamental characteristics of the braking system. Aperture processing enabling more extensive deformation in the EDC can notably interrupt FIVN continuity, showing clear intermittent characteristics, while potentially increasing FIVN intensity. The EDC mainly affects the tribological behavior by influencing contact characteristics such as the oscillation intensity of contact area and frictional force, thereby altering the characteristics of FIVN. The overall deformation of the EDC has a considerable effect on the movement of braking interface debris, as well as wear patterns, eccentric wear, and contact plateaus characteristics. An improperly designed deformation area in the EDC can lead to excessive softness, challenging the block's ability to maintain consistent contact with the brake disc. This issue often causes pronounced eccentric wear on the block and considerable material detachment at the wear site, which triggers intense FIVN.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"560 ","pages":"Article 205599"},"PeriodicalIF":5.3,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531156","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 results indicate that the rail steel is primarily composed of bainite and martensite after isothermal quenching. Compared to the pearlitic microstructure before isothermal quenching, the mixed martensite and bainite microstructure of rail steel achieved by isothermal quenching effectively mitigates rolling contact damage and resists plastic deformation. This improvement is associated with increased material hardness, reduced grain angles and grain refinement.

This hardening layer effectively hinders crack propagation to greater depths.
