Cu-rich and Fe-Cr-rich precipitates were present within the BCC phase, while small amounts of needle-like precipitates were observed in both the FCC1 and the FCC2 phases. After annealing at 700°C, the matrix phase composition of the alloy did not change significantly, but the volume fraction and size of the needle-like precipitates increased with the holding time. The hardness and yield strength first increased and then decreased with the extension of the holding time, reaching peak values at 48 h of holding time of 364 HV and 667 MPa, respectively. During annealing at 900°C, the volume fraction of needle-like phases first increased and then decreased with prolonged holding time, while the precipitates underwent significant coarsening. The hardness and yield strength reached peak values at 1 h of holding time of 311 HV and 493 MPa, respectively. During the subsequent holding process, as the needle-like phase significantly coarsened, the mechanical properties of the alloy steadily declined, which led to the overall mechanical properties after annealing at 700°C being superior to those after annealing at 900°C.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 6","pages":"4545 - 4556"},"PeriodicalIF":2.1,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091184","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}

However, most models do not represent its physiological nature. This research aims to characterize the rheological properties of bone fluid flow. Fresh bone samples were harvested from human knees with osteoarthritis (OA), and subjected to tests to evaluate their viscosity using a rheometer. This study revealed that the dynamic viscosity of the fluid varied with time and shear rate, indicating non-Newtonian fluid behavior. Modeling was performed using the power-law model in Python. The power-law model applied in this study proved highly effective in describing the rheological behavior of bone fluid. The fit showed remarkable precision, with a coefficient of determination <i>R</i><sup>2</sup> = 0.9995, highlighting the excellent agreement between the experimental data and the model. These results suggest that variations in bone fluid viscosity, induced by mechanical stresses, could modulate osteocyte stimulation and influence bone remodeling in the context of OA. This research represents a significant advance in the understanding of bone fluid, and the knowledge gained could be fundamental for developing new therapeutic strategies in tissue engineering and regenerative medicine.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 6","pages":"4260 - 4272"},"PeriodicalIF":2.1,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091108","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}

The results indicate that, following electrochemical pre-hydrogenation, the tensile strength of the material is marginally enhanced, while its plasticity is significantly diminished. Furthermore, its elongation is reduced from 30.91% in the absence of pre-hydrogenation to 22.35% in the presence of pre-hydrogenation. Additionally, the fatigue life following pre-hydrogenation was observed to diminish by 15%. The rate of crack propagation is approximately four times that observed in the absence of pre-hydrogenation.
