“…In case of the cemented carbides with ultrafine WC@10Co up to 16.67 wt-%, the hardness was consistent with this relationship. However, for the cemented carbide with 22.22 wt-% ultrafine WC@10Co and decreasing grain size, the hardness was reduced because of a decreasing relative density and a decreasing number of HCP-Co that may destroy the hardness [31].…”

“…Figure 8 shows the cumulative mass loss curves of WC-5Co, WC-8Co, and WC-10Co The results of residual compressive stress on the surface of WC-5Co, WC-8Co, and WC-10Co (untreated and DCT) are shown in Table 3. DCT can significantly increase the residual compressive stress of WC in cemented carbides; this is because when WC-Co receives deep cryogenic treatment, the low-temperature environment produces compressive and tensile stresses on WC and Co, and the resulting residual stresses increase the overall hardness and improve the wear resistance [33][34][35] (and, at the same time, the presence of residual stresses promotes the transition from α-Co to ε-Co, which has a higher corrosion resistance compared to α-Co [36][37][38][39]). In this experiment, the residual compressive stress of the WC surface in WC-5Co, WC-8Co, and WC-10Co increases by 84.11%, 91.38%, and 65.03%, respectively.…”
