The Cu-Zr-Al bulk metallic glasses have known by their high glass forming abilities, however their low ductility hinder their effective applicability. Therefore addition of rare-earth elements and production of amorphous/crystalline composite (ACC) materials by in situ and by ex situ methods provide better mechanical properties compared to their monolithic amorphous or crystalline alloys. This current study details the investigation of thermal stability, crystallization kinetics and mechanical properties of Sm microalloyed Zr-Cu-Al bulk metallic glasses and their nanocomposites using combined characterization techniques including differential scanning calorimetry (DSC), X-ray diffraction (XRD), electron microscopy, hardness and compression tests. This study will present and discuss the devitrification dynamics and crystallization kinetics under both continuous and isothermal annealing conditions. This work has been supported by TUBITAK under the grant number 117M295.
