Methods of Ex Situ and In Situ Investigations of Structural Transformations: The Case of Crystallization of Metallic Glasses

8.9K
Here, we present a protocol to describe ex situ and in situ investigations of structural transformations in metallic glasses. We employed nuclear-based analytical methods which inspect hyperfine interactions. We demonstrate the applicability of Mössbauer spectrometry and nuclear forward scattering of synchrotron radiation during temperature-driven...

Properties of Transition Metals

29.6K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

Phase Transitions: Melting and Freezing

14.6K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Optimized Sealing Process and Real-Time Monitoring of Glass-to-Metal Seal Structures

7.8K
Key procedures to optimize the sealing process and achieve real-time monitoring of the metal-to-glass seal (MTGS) structure are described in detail. The embedded fiber Bragg grating (FBG) sensor is designed to achieve online monitoring of temperature and high-level residual stress in the MTGS with simultaneous environmental pressure...

Summary
This summary is machine-generated.

Researchers studied metallic glass alloys, observing a liquid-liquid transition with slow kinetics. This suggests long-range mass transport, unlike transitions in oxides or molecular liquids.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Physical Chemistry

Background:

  • Bulk metallic glasses (BMGs) exhibit complex liquid structures and dynamics.
  • Understanding the glass transition is crucial for BMG applications.
  • Previous studies on BMGs often focused on local structural changes.

Purpose of the Study:

  • To investigate the structure and dynamics of specific BMGs during cooling.
  • To identify and characterize the liquid-liquid transition in these alloys.
  • To elucidate the mechanism governing the transition kinetics.

Main Methods:

  • In situ synchrotron X-ray diffraction.
  • Quasielastic neutron scattering.
  • Electrostatic levitation for high-temperature melt studies.

Main Results:

  • An abrupt change in the temperature dependence of the first structure factor maximum was observed.
  • The kinetics of the observed liquid-liquid transition are on the order of tens of seconds.
  • The transition onset temperature showed weak dependence on the cooling rate.

Conclusions:

  • The slow kinetics indicate a need for long-range mass transport during the liquid-liquid transition.
  • This finding contradicts mechanisms involving only local structural changes, as seen in oxides or molecular liquids.
  • The study provides new insights into the fundamental behavior of metallic glass melts.
