“…Figure 1 compares XRD patterns of the initial powder mixture and as-prepared copper composites. It can be seen that in the initial mixture, diffraction peaks of Cu were strong, and weak peaks of V 2 SnC and Sn were detected [35] (Figure 1a). Figure 1b-e show XRD spectra of S1, S2, S3, and S4, respectively, corresponding to 5%, 10%, 20%, and 30% volume content of V 2 C. Diffraction peaks of V 2 SnC and Sn disappeared, and those of V 2 C occurred.…”

In this paper, in situ V2C-reinforced Cu composites were successfully fabricated by hot pressing at 750 °C under 25 MPa using Cu and V2SnC powders. Due to decomposition of V2SnC to V2C and Sn during sintering, Sn atoms entered the crystal structure of Cu. Therefore, final compositions of composites consisted of Cu(Sn) and V2C phases. Here, copper composites with 0, 5, 10, 20, and 30 vol.% V2C were designed. Their microstructures and physical and mechanical properties were systematically investigated. It was observed that with increasing V2C content, electrical conductivity decreased from 0.589 × 108 S·m−1 to 0.034 × 108 S·m−1 and thermal conductivity decreased from 384.36 W⋅m−1⋅K−1 to 24.65 W·m−1·K−1, while Vickers hardness increased from 52.6 HV to 334 HV. Furthermore, it was found that composites with 20 vol.% V2C had the highest tensile strength (440 MPa).

“…Recently, an interesting phenomenon of whisker growth on MAX phases has drawn increasing attention [ 24 , 25 , 26 , 27 , 28 ]. The MAX phases are layered and hexagonal early transition-metal carbides and nitrides, with a general formula of M n+1 AX n (where n = 1, 2, 3; M: early transition metal; A: A-group element; X: C or N) [ 29 , 30 , 31 , 32 ].…”

“…However, due to the weak bonding between the M 6 X-octahedron layer and the A-atom layer, A-site atoms can be easily released from the lattice points of the MAX phase during mechanical exfoliation [24,25,27]. So far, there have been some reports [26][27][28]35,36] confirming that A-site metal whiskers (such as Ga, Sn, and In whiskers) can grow on the corresponding MAX phases (Cr 2 GaC, Ti 2 SnC, and Ti 2 InC, respectively). Zn-containing MAX phases (e.g., Ti 2 ZnC, V 2 ZnC, and Ti 3 ZnC 2 ) were successfully synthesized by Huang Qing et al [37].…”

ZnO whiskers have many applications, such as in medical and photocatalysis fields. In this study, an unconventional preparation approach is reported, realizing the in-situ growth of ZnO whiskers on Ti2ZnC. The weak bonding between the layer of Ti6C-octahedron and the Zn-atom layers leads to the easy extraction of Zn atoms from Ti2ZnC lattice points, resulting in the formation of ZnO whiskers on the Ti2ZnC surface. This is the first time that ZnO whiskers have been found to grow in-situ on Ti2ZnC substrate. Further, this phenomenon is amplified when the size of the Ti2ZnC grains is mechanically reduced by ball-milling, which bodes a promising route to prepare ZnO in-situ on a large scale. Additionally, this finding can also help us better understand the stability of Ti2ZnC and the whiskering mechanism of MAX phases.
