Primary crystallization kinetics in rapidly quenched Mg-based Mg–Ni–Y alloys

Influence of partial replacement of cerium-rich mischmetal (CeMM) by yttrium on the crystallization and mechanical properties of amorphous Mg80Ni10CeMM10 alloy

“…Less attention, however, has been dedicated to the microstructural and mechanical characterization of these alloys [2,12]. A renewed interest on MgeTMeY based alloys (TM ¼ Ni or Cu) as potential candidates for structural applications could arise from the formation, during the crystallization from the amorphous state, of long period ordered (LPO) structures in which a (Y,TM)-plane is intercalated between a sequence of pure magnesium planes [13].…”

Mechanical behaviour of amorphous Mg–23.5Ni ribbons

“…In the case of magnesium alloys, much research has been addressed to develop systems with a good glass-forming ability in a large compositional range, as for Mg-M-Ln alloys, where M is nickel or copper and Ln a lanthanide element [6][7][8][9][10][11][12]. Glass transition and crystallization kinetics of these alloys have been extensively studied by different researchers [7][8][9][10][11][12].…”

“…Glass transition and crystallization kinetics of these alloys have been extensively studied by different researchers [7][8][9][10][11][12]. It has been observed that these amorphous magnesium alloys display a certain thermal stability which allows to synthesise them as bulk materials by different techniques such as metallic mould casting or squeeze casting [13,14].…”

Devitrification of rapidly solidified amorphous Mg–Ni–Y–LaMM ribbons

“…Then, amorphous neighbour regions were substantially enriched in nickel and yttrium (Mg 70 Ni 19 Y 9 Nd 2 ). An yttrium content of about 9% is high enough to stabilise the amorphous structure up to higher temperatures, as reported in many ternary amorphous Mg-Ni-Y alloys [2][3][4][5][6][7]. Moreover, some magnesium crystallises during the final stage of Mg 17 RE 2 crystallisation, as noticed by the presence of magnesium peaks in the XRD pattern (point d 2 in DSC curve).…”

“…In the case of nickel-containing alloys, numerous studies have proved that alloys belonging to the Mg-Ni-Y [2][3][4][5][6][7] or Mg-Ni-RE [8][9][10] systems possess excellent glass forming ability. Information on the crystallisation of amorphous ternary Mg-Ni-Y or Mg-Ni-RE alloys is relatively abundant, but there are very few data in the literature on quaternary Mg-Ni-Y-RE alloys, especially when rare earth elements are added as mischmetal (MM) [11][12][13][14][15].…”
