The objective is to improve the tribological performance and tool lifespan of the GH4169 alloy through machining, focusing specifically on the potential benefits of using cryogenic cooling. Hence, the experiments are conducted under liquid nitrogen (LN2), carbon dioxide (CO2), and minimum quantity lubrication (MQL) conditions. The test results proved that cryogenic cooling with the inclusion of MQL helps improve tool life with better tribological characteristics. The maximum power dissipation efficiency is identified as 44%. Stable regimes such as DRX are observed at 360 °C for GH4169. The tool flank wear was reduced by 15.8%, 36.8%, and 52.6% for CO2, MQL, and LN2 compared to the dry alloy. Therefore, applying MQL to the GH4169 alloy significantly impacts hot deformation and wear behavior. The formation of DRX structures in the processing map is crucial to improving the mechanical properties of these cast components.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"20 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268938","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}

Therefore, improving the fatigue resistance of such kind of alloys is of great significance for their engineering application. In this research, C17200 beryllium-copper alloy was surface strengthened by means of a self-designed surface mechanical rolling treatment (SMRT) device. The fatigue behavior before and after SMRT was investigated using a ball-on-rod rolling contact fatigue (RCF) machine, and surface failure mechanisms were analyzed. It was found that the RCF resistance of the untreated C17200 alloy was weakened with the increase in the maximum Hertzian contact stress (σmax). After surface treatment, C17200 alloy exhibited superior RCF resistance subjected to SMRT with a static rolling force of 200 N. But among the specimens treated by SMRT, the RCF resistance of beryllium-copper alloys was weakened with the increase in the SMRT static rolling force. The RCF life of specimens treated by SMRT with a force of 400 N is similar to that of untreated specimens, while the RCF lives of specimens treated by SMRT with a force of 735 and 980 N are even lower than that of untreated specimens. Thus, applying the appropriate static rolling force during SMRT can improve the surface quality and compressive residual stress, as well as enhance the fatigue resistance of C17200 alloys.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"54 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253586","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}

In addition, the grain size of the solid solution aging treated sample was larger compared to the annealed sample.

This weakened the dislocations accumulation and entanglement at the grain boundaries, resulting in change in grain orientation, thereby reducing the texture strength of the sample.

However, only the solid solution treatment and 15% pre-deformation can significantly enhance the room damping capacity; while, 15% pre-deformation followed by aging treatment reduces the room damping capacity due to the strong pinning of denser precipitates induced by the peak aging treatment.

The microstructure and corrosion resistance of the composite coating before and after remelting were comparatively studied. The results showed that the entropy value of CoCrFeNiTi-B4C composite coating after laser remelting still conformed to the definition of HEA. Moreover, there were almost no defects in the remelted coating, and a metallurgical bonding was formed between the remelted coating and the substrate. The remelted coating was dominated by FCC solid solution, with in-situ generation of TiC phase and (Fe,Cr)2B phase. Among them, the (Fe,Cr)2B phase was surrounded by (FCC + BCC) phase, forming a unique eutectic structure.

In addition, long-term immersion corrosion test also demonstrated that the corrosion resistance of the remelted coating was significantly better than that of the as-sprayed coating.
