Sa. Makhlouf et al., FORMATION OF NOMINAL NI AMORPHOUS PHASE BY MECHANICAL MILLING AND LEACHING, Journal of alloys and compounds, 199(1-2), 1993, pp. 119-124
A nominal Ni amorphous phase was obtained by leaching Al atoms from me
chanically alloyed Ni40Al60 amorphous alloy. X-ray diffraction, transm
ission electron microscopy and magnetization measurements were utilize
d to characterize the as-milled and leached specimens. The Ni amorphou
s phase is a strong paramagnet and transforms to a ferromagnetic f.c.c
. phase above 500 K.
