“…In recent years, rare earth-based (RE-based) bulk metallic glasses (BMGs) have attracted increasing interests due to their novel physical properties and potential applications in the future, such as high glass-forming ability (GFA) [1][2][3], special magnetic properties [4][5][6], superplasticity and thermoplasticity in supercooled liquid region [3,7,8]. La-Al-Co metallic glass is one of La-based bulk metallic glasses with superior GFA and lower glass transition temperature [9,10], it shows regularly increasing of thermal stability, Vicker's hardness H v and fracture strength r f with the increase of elastic constants and the strong liquid behavior.…”

“…La-Al-Co metallic glass is one of La-based bulk metallic glasses with superior GFA and lower glass transition temperature [9,10], it shows regularly increasing of thermal stability, Vicker's hardness H v and fracture strength r f with the increase of elastic constants and the strong liquid behavior. Since the structural relaxation changing the properties of BMGs will take place after the BMGs were annealed near glass transition temperature (T g ), understanding the kinetics of glass transition of the alloy is of importance to determine the thermal stability and the mechanism of glass transition.…”

“…From the viewpoint of thermodynamics, the GFA of metallic glasses is related to the mixing enthalpy ( H) [41][42][43][44][45], mismatch entropy normalised by the Boltzmann constant (S σ /k B ) [44][45][46][47][48], and their product ( H • S σ /k B ) [47,48] values in a multicomponent system. The mixing enthalpy of a multicomponent system can be determined by the extended regular solution model:…”

The effects of Al element addition and partial substitution of Ce with La, Pr, and Nd on the two-glass-forming ability of the phase-separating Zr–Ce–Co–Cu alloy system have been studied. The distribution of the additions in the two coexistent immiscible liquids was analysed thermodynamically. The results indicate that Al almost equally distributes in the two liquids, whereas the elements La, Pr, and Nd are predominantly found in the Ce–Cu-rich liquid. X-ray diffraction analysis reveals that these additions obviously enhance the two-glass-forming ability of the coexisting liquids. This work presents a strategy for improving the two-glass-forming ability of immiscible alloys to obtain phase-separated bulk metallic glasses.

“…The bulk metallic glasses (BMGs) have attracted much attention due to the unique properties and potential applications as functional materials [1][2][3][4][5][6][7][8][9]. The Ce-Cu system is one of the sub-systems of the Ce-based bulk metallic glasses with an exceptionally low glass transition temperature [4,10].…”
