Influence of carbon and nitrogen addition on microstructure and hot deformation behavior of biomedical Co–Cr–Mo alloy

Effect of carbon on the microstructure, mechanical properties and metal ion release of Ni-free Co–Cr–Mo alloys containing nitrogen

“…The formation of M 23 C 6 is very important with respect to grain refinement. Li et al [30] have suggested that the formation of carbide particles enhances grain refinement in Co-Cr-Mo alloys, owing to dynamic recrystallization. This is because the difference in the hardnesses of the carbide phase and the surrounding γ-matrix introduces dislocations.…”

Effects of microstructures on the sliding behavior of hot-pressed CoCrMo alloys

“…It is interesting to find that LC-wrought with much higher initial contact pressure experienced relative less Table 3 The average coefficient of friction (μ) and wear factor ( SIM, since the stacking fault energy is decreased and the γ-F.C.C. is much stabilized by nitrogen addition [19,20].…”

“…However, microstructures generated under various processes or heat treatments showed different responses to expectation, and if the matrix phase constitution and the type, morphology, size, distribution of the carbide and nitride precipitates are improperly controlled, they would accordingly result in loss of the desired properties or potential material failure [3] [14][15][16][17][18][19][20]. To date, few researches have been focused on the tribological properties of the HP CoCrMo alloys with various microstructures.…”

Effects of Antibacterial Co‐Cr‐Mo‐Cu Alloys on Osteoblast Proliferation, Differentiation, and the Inhibition of Apoptosis

“…Therefore, as alloys are designed, to maintain excellent deformability and ductility, the FCC γ-Co phase is always preferred 20,21 . It has been reported that the HCP phase could be reduced by adding nitrogen, carbon, and nickel to the alloy [22][23][24] . In this study, the HCP phase was decreased by adding the copper, as verified by the XRD peak patterns shown in Figure 1.…”
