| Abstract Scope |
Structural differences depending on processing lead to materials with different properties and performance. In the presence of multiple phases, the thermal characteristics, particularly where the phase transformations occur, can be influenced by the interfaces between them, with a potential impact on the mechanical properties, such as ductilization and higher fracture toughness.
Here, the effect of the phase interfaces on the phase transformation (glass transition and crystallization) kinetics in Pd-Au-Si MG. Fast differential scanning calorimetry (FDSC) revealed double glass transition and crystallization events, indicating phase separation. TEM analysis elucidated the correlation between the phase interface and the transformation kinetics. Moreover, uniaxial micropillar compression tests demonstrated the impact of the microstructural evolution on mechanical properties.
We anticipate that our study will provide a framework for exploring the relationship between processing, microstructure, and performance based on the advanced understanding of the interfacial effect on phase transformation kinetics and mechanical properties in metallic glasses. |
