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}

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.

High fraction of recrystallization were caused by ultrasonic vibration, and the specimens with 5.3 specimen vibration amplitude could reach 61.47%. Besides that, Goss texture were weakened during ultrasonic vibration assisting hot compression. Because of the comprehensive influence of large size of η´ (softening effect) and refined grain size (hardening effect), a slight decreased trend of hardness value is observed for the specimens under ultrasonic vibration assisting hot compression.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23202 - 23210"},"PeriodicalIF":2.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284299","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}
