The mechanism of work hardening of SiCp/Al composites is discussed by analyzing the slip and expansion of dislocations inside the workpiece, the obstruction of dislocations of SiC particles, and the interaction between dislocations. The impact of vibration-assisted cutting on internal work hardening of the workpiece was analyzed by comparing the variation of cutting force, internal dislocation density, and distribution of the workpiece under normal cutting and vibration cutting. The results show that in the cutting process, the presence of obstacle SiC particles will change the slip path of the dislocation, and the phenomenon of pinning points. “V” type dislocations, dislocation entanglements, and dislocation plugging formed inside the workpiece will aggravate the plastic deformation of the crystal, resulting in the generation of work hardening. The cutting force and dislocation density during vibration-assisted cutting are lower than that of normal cutting, and intermittent cutting significantly reduces the work hardening of the workpiece.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23404 - 23417"},"PeriodicalIF":2.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additional to the external optimization of friction pairings, solid lubricants can be structurally incorporated into metallic matrix by designing self-lubricating composite materials. Microstructural characteristics of these composites such as the amount, chemical composition and distribution of solid lubricants distinct influence the property profile, especially the tribological behavior of bulk materials. Besides the bulk material composition, the lubrication effect is related to the contact condition during wear testing. Molybdenum disulfide (MoS<sub>2</sub>) was investigated as promising solid lubricant for the Ni-based alloy NiCrBSiFe. Microstructure, hardness and wear behavior of the spark-plasma sintered composites with MoS<sub>2</sub> contents up to 10 wt.% were determined in this study. The best friction behavior was observed for the composite containing 7.5 wt.% MoS<sub>2</sub>. The coefficient of friction for this composite is more than halved compared to the NiCrBSiFe reference. Simultaneously, the wear rate is reduced from 0.41 to 0.15 × 10<sup>−4</sup> mm<sup>3</sup>/Nm due to MoS<sub>2</sub> incorporation at higher wear loads of 26 N. Based on the overall tribological results, the composite with 10 wt.% MoS<sub>2</sub> was laser surface hardened using a high-power 10 kW diode-pumped solid-state laser. An adherent Fe/Ni sulfide top-coat and CrS precipitates were formed. Compared to the unfused condition, the laser hardened composite exhibited 200 HV0.5 higher hardness and a similarly high wear resistance.
