Influence of TM and RE elements on glass formation of the ternary Al–TM–RE systems

Thermal stability of the Al70Ni10Ti10Zr5Ta5 amorphous alloy powder fabricated by mechanical alloying

“…It can be observed that both the T onset x and T x of the 120 h milled powder are greater than previously reported values for other Al-based amorphous alloys [2,6,9,18,32], suggesting that it is more stable than those of previously reported Al-based amorphous alloys [33]. The comparison of the crystallization temperatures T onset x and the supercooled liquid region T x between the Al 70 Ni 10 Ti 10 Zr 5 Ta 5 alloy powder and relevant alloys are shown in Table 2.…”

Structural and mechanical characterization of rapidly solidified Al95Ni5 and Al93Ni5Mm2 alloys prepared by centrifugal atomization

“…One can see that both alloys have heterogeneous crystalline structure, i.e. they are not fully amorphous, despite a large GFA of the Al-Ni-Mm system [10,11]. Fig.…”

“…RS Al-Ni-RE alloys have been extensively studied so far and it has been demonstrated that they fall into a group of alloys showing high GFA and, therefore, excellent mechanical properties [10][11][12]. In contrast to most of studies reported so far, we investigate an alloy containing a relatively low atomic percentage of Mm in this study, because high costs of RE metals are main barriers for mass production and application of Al-TM-RE alloys.…”

Role of rare-earth elements in glass formation of Al–Ca–Ni amorphous alloys

“…Thus, widespread uses of Al-based amorphous alloys have still been restricted because of their small critical size. Presently, most of the reported Al-based metallic glass systems typically contain 3-20 at.% RE (rare-earth) metal elements [9], which sacrifices the specific strength because of the high density of the RE elements. Therefore, it is necessary to understand further about glass formation in Al-based alloy systems and to explore potential good glass formers which contain limited contents of RE metals.…”
