A Large Tensile Elongation Induced by Crystallization in an Amorphous Al 88 Ni 10 Ce 2 Alloy
TLDR
In this paper, an Al 88 Ni 10 Ce 2 amorphous alloy with two-stage crystallization process was shown to exhibit a large elongation reaching 45% in the temperature range of 450 to 465 K. The appearance of the significant elongation is due to a crystallization-induced elongation phenomenon.Abstract:
An Al 88 Ni 10 Ce 2 amorphous alloy with the two-stage crystallization process of amorphous→amorphous plus fcc-Al→Al plus compounds exhibited a large elongation reaching 45% in the temperature range of 450 to 465 K. The temperature range agrees with that where the primary Al particles with a size of about 12 nm precipitate homogeneously at an interparticle spacing of about 6 nm in the amorphous matrix. It is therefore concluded that the appearance of the significant elongation is due to a crystallization-induced elongation phenomenonread more

New Amorphous Alloys with Good Ductility in Al-Ce-M (M=Nb, Fe, Co, Ni or Cu) Systems : Condensed Matter
TL;DR: The compositional range is the widest for Al-Ce-Ni alloys and extends from 2 to 15 at% Ce and below 30%Ni as mentioned in this paper, where the effect of M elements on Tx and hardness is interpreted by taking the bonding nature of Ce and M atoms into consideration.
