Stoichiometry Splitting of β Phase in Ni-Al-Mn, Ni-Al-Co and Ni-Al-Fe Ternary Systems

MATERIALS TRANSACTIONS, 2001
The stoichiometry of the ternary β phase in the Ni-Al-Mn, Ni-Al-Co and Ni-al-Fe systems has been studied through the measurements of hardness and lattice parameter. It is shown that twit stoichiometry lines are observed in the β phase region of the Ni-Al-Mn ternary system.

Structure And Corrosion of Quasicrystalline Cast Al–Co–Ni and Al–Fe–Ni Alloys in Aqueous NaCl Solution

East European Journal of Physics, 2020
In this work the structure and corrosion behavior of quasicrystalline cast Al69Co21Ni10 and Al72Fe15Ni13 alloys in 5-% sodium chloride solution (рН 6.9–7.1) were investigated. The alloys were cooled at 5 К/s.
