Abstract: The effects of TM and RE elements on glass formation ability (GFA) of the Al-TM-RE systems are studied systematically. The TM elements show distinct differences: critical sizes of the Al-TM-Ce systems are in the order of Ni > Co > Fe > Cu. However, the RE elements show similar effect on glass formation. These results are discussed in terms of the GFA-related factors, i.e., reduced glass transition temperature (Trg = Tg (Tx)/TL, where Tg, Tx and TL are the glass transition temperature, onset crystallization temperature and liquidus temperature, respectively) and the mixing enthalpy ΔHAl-TM. A new parameter of TL - Tg (Tx) is potentially proposed and used to evaluate the GFA of the Al-based alloys, as well as bulk glass-formers. © 2008 Elsevier B.V. All rights reserved.
