| 英文摘要 | Eight novel transition metal carbides, nanolaminated (Cr2/3R1/3)2GaC (R=Y, Tb, Dy, Ho, Er, Tm, Yb and Lu) with R in-plane chemical ordered occupation, have been synthesized with mainly Cmcm orthorhombic structure and monotonously decreased lattice parameters due to lanthanide contraction. Stacking disorderings and highdensity slidings within c plane have been observed. Two characteristic in-plane sliding, along [100] or [130]o directions have been analyzed with former one leading into the structural evolution between Cmcm and C2/c symmetry. Such an atomic scale co-existence of Cmcm and C2/c structures is explained by more negative charge for Ga and anisotropic bonding with Ga compared with A=Al case. Thus, the Vickers hardness, fracture strength and increased wear depth are reduced in representative (Cr2/3Lu1/3)2GaC i-MAX bulk compared with the (Cr2/ 3Lu1/3)2AlC counterpart. |
