Characteristics of Fluids01:31

Characteristics of Fluids

Fluids differ from solids primarily in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation. In contrast, fluids have molecules spaced farther apart with weaker forces, allowing them to flow and deform easily.
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...

Characteristics of Fluids

When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...
Fluid Mosaic Model01:34

Fluid Mosaic Model

The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.LipidsThe most...

Area of Science:

  • Materials Science
  • Condensed Matter Physics

Background:

  • Shape memory effect (SME) is typically observed in crystalline materials and polymers, driven by phase transitions like martensitic transformation or glass transition.
  • Metallic glasses (MGs) are amorphous alloys known for their unique mechanical properties, but SME has not been previously reported in them far below their glass transition temperatures.

Purpose of the Study:

  • To investigate and report the occurrence of shape memory effect (SME) in metallic glasses (MGs) at temperatures significantly below their glass transition.
  • To elucidate the underlying mechanism responsible for SME in MGs and its dependence on training parameters.

Main Methods:

  • Experimental characterization of SME in MGs under varying training temperatures, stresses, and times.
  • Microstructural analysis to understand the role of local liquid-like regions (LLRs) and medium-range ordered (MRO) structures.
  • Thermodynamic modeling to explain the activation kinetics of LLRs and atomic rearrangements.

Main Results:

  • SME was successfully demonstrated in MGs at temperatures far below their glass transition.
  • Recoverable strain in MGs increases with training temperature, stress, and time.
  • The SME mechanism involves the activation of low-viscosity, liquid-like regions (LLRs) and rearrangement of unstable medium-range ordered (MRO) structures, distinct from the rigid MRO string-like structure of the matrix.

Conclusions:

  • SME in MGs is an intrinsic phenomenon attributed to dynamic structural heterogeneity, specifically the interplay between LLRs and the elastic matrix.
  • The activation of LLRs follows an Arrhenius-type relationship with temperature and time, involving atomic displacements and MRO rearrangement.
  • This research reveals a novel mechanism for SME in metallic glasses, paving the way for developing new functional glassy materials with shape memory properties.
