Metal Science and Treatment of Metals| Резюме: | The effect of V on the formation of the structure, phase composition, and microhardness of high-eltropy AlCoNiFeCrTiVx coatings obtained by electron-beam cladding on a steel substrate in vacuum is investigated. It has been established that AlCoNiFeCrTiV0 coatings consist of two bcc solid solutions with different lattice periods and a small amount of intermetallic s-phase. An increase in V content from x = 0 to x = 1.5 changes the phase composition of the coatings and they consist of one bcc solid solution and s-phases of different composition. With increasing content of V, the volume fraction of the s-phase increases. The addition of V to AlCоNiFeCrTi shows the strengthening effect of the AlCоNiFeCrTiV0-1.5 coatings and the Vickers hardness increased from 8,4 to 11 GPa. |
