Abstract

A series of bulk metallic glasses (BMGs) based on the rare-earth (RE) elements in lanthanum family have been obtained by a copper mold casting method. These chemical comparable RE elements with ‘continuous’ range of atomic size, electron structure and elastic constants may provide a good system for systematically exploring the BMG-forming characteristics. The glass-forming ability, elastic properties, thermal stability and their correlations in the RE-based BMGs have been investigated.

      La-based metallic glasses (MGs) have aroused processive attentions due to their unique atomic structure, fantastic physical properties, attractive chemical comparability, good thermoplasticity and moderate mechanical properties, which are considered as desirable model materials for scientific research and promising functional materials for industrial applications [1–9].

      The Ce based metallic glass (MG) with an exceptionally low glass transition temperature Tg, similar to or lower than that of many polymers, has generated lot of interest owing to their thermoplastic behavior near room temperature, excellent magnetocaloric effect and potential applications as glassy materials [7–10]. A number of novel rare-earth (RE) based (such as Ce-, Dy-, Er-, Sm-, Y-) metallic glasses, have been developed recently by choosing compositions with addition of other elements having superior glass forming ability (GFA) [11–13]. Recently, a new ternary Ce–Al–Ga glass forming system was found with highly improved glass forming ability [14,15].

      Since ternary La–Al–Ni bulk metallic glasses (BMGs) with a diameter of 2.5 mm were successfully fabricated by copper mold casting [1], the rare earth (RE) based BMGs have received a great deal of attention due to the scientific and technological interest in the past decades. A number of novel RE-based BMGs, such as Ce-, Dy-, Er-, Sm-, Y- based BMGs, have been developed recently by choosing particular multi-component alloys with high glass forming ability (GFA), i.e., a strong tendency to form a glassy phase [2–11]. A straightforward indicator of GFA is the critical cooling rate (Rc), the minimum cooling rate to obtain fully amorphous solid from melts, or the maximum attainable size (Dmax) for glass formation, which strongly depends on the fabrication method used.

      Since ternary La-based bulk metallic glasses (BMGs), La–Al–Ni, with a diameter of 2.5 mm were successfully fabricated by copper mold casting [1], the rare earth (RE) based BMGs have attracted a great deal of attention due to the scientific and technological interest in the past decade. A large number of novel RE-based BMGs, such as La-, Ce-, Er-, LaCe-, Y-, Sm-based BMGs, have been developed recently by choosing particular multi-component alloys with a strong tendency to form a glassy phase [2–12]. The tendency to form a glassy phase, i.e., the glass forming ability (GFA), is frequently evaluated by critical by critical cooling rate (Rc), which is the minimum cooling rate to obtain fully amorphous solid from melts, or the maximum attainable size (Dmax) for glass formation, which strongly depends on the fabrication method used; the systems with Rc less than approximately 105 K/s are regarded as high GFA alloys.

      The studies of the acoustic, elastic and thermal properties of metallic glasses can also provide important information about the vibrational characteristics [94,95]. With the recent development of a variety of metallic glasses which readily form bulk glass, significant amounts of data on their elastic and acoustic properties have indeed been obtained [54–58,82,87,99–146]. It is noted that the obtained elastic data of these BMGs are in good agreement with that measured using different methods [96–98].
