Corrigendum to“Strengthening mechanism of cemented carbide containing Re” [Mater. Sci. Eng. A 838 (2022) 142803]

The authors regret that after publication, they discovered that Fig. 8(b) is not properly supplied. During preparation of Fig. 8, the four figures are copied from the file folder and pasted into PPT software, and then combined to be a single Fig. 8. Due to carelessness, Fig. 8(c) is misplaced in the top right part of Fig. 8, and the original Fig. 8(b) was not included in Fig. 8. Fig. 9 shows the grain boundary distribution of the cemented carbide with different Re addition. Compared Fig. 9 with Fig. 8, Fig. 9(a), 9(c), and 9(d) are similar to Fig. 8(a), 8(c), and 8(d), and Fig.9b gives the correct grain boundary distribution of sample R2. Additionally, there is a typographical error of symbol (>) in the caption of Fig. 8, and a sentence in section 3.3 has a missing word (almost). Corrections to Fig. 8, along with the revised captions and related sentence are provided below: (1) Revised Fig. 8 and caption[Formula presented] Fig. 8. WC grain boundaries distribution of small-angle grain boundary (<15°) highlighted in black and large-angle grain boundary (>15°) highlighted in red with the samples of: (a) R1, (b) R2, (c) R3, (d) R4.(2) Section 3.3“However, the number of small angle grain boundaries does not change.” should be revised as “However, the number of small angle grain boundaries almost does not change.” Nevertheless, the corrections do not change all the original conclusions in section 4, and the key statement in section 3.3 still stands: with the addition of Re, the grain size of cemented carbide decreases and the number of grain boundaries increases. There are more large-angle grain boundaries in the cemented carbides doped with Re. The authors would like to apologize for any inconvenience caused.
