An Er-based bulk metallic glass with high thermal stability and excellent magnetocaloric properties

Correlation between thermodynamics and glass forming ability in the Al–Ce–Ni system

“…A large number of novel amorphous alloy systems based on various elements have been developed recently [3][4][5][6][7]. Meanwhile, many criteria for evaluating the glass forming ability (GFA) of an amorphous alloy have been proposed [8][9][10][11][12].…”

Unconventional elastic properties, deformation behavior and fracture characteristics of newly developed rare earth bulk metallic glasses

“…These new alloys show totally different thermal and elastic properties with respect to conventional BMGs [10][11][12][13][14][15][16][17][18][19][20][21][22]. For example, these materials exhibit a very low glass transition temperature, T g , a large supercooled liquid region and rather low Young's modulus (lower than in conventional Al-based or Mg-based crystalline metallic alloys).…”

Influence of sample geometry on determination of magnetocaloric effect for Gd60Co30Al10 glassy ribbons using direct and indirect methods

“…In most cases metallic glasses also show secondorder magnetic phase transition with very low hysteresis losses, because the lack of long range atomic order prevents effective magnetic domain wall pinning (on the condition that residual stress/strain has been removed by proper heat treatment for most alloys). The maximum entropy change of Gd- [15][16][17][18][19][20][21], Dy- [22], Ho- [23] and Er-based [24] metallic glasses is comparable in size with that of conventional crystalline Gd [25] and, furthermore, the continuous variability of composition within a certain range allows to tune the ordering temperature. Additionally, the absence of atomic long range order causes high electrical resistivity and minimizes eddy current heating caused by fast varying magnetic fields [26].…”
