Metallic Solids02:37

Metallic Solids

18.4K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Molecular and Ionic Solids

17.1K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Recrystallization: Solid–Solution Equilibria01:10

Recrystallization: Solid–Solution Equilibria

1.1K
Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

Thin-Walled Hollow Shafts

192
In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution...

Structures of Solids02:22

Structures of Solids

14.1K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Mechanical Characteristics of Steel01:18

Mechanical Characteristics of Steel

577
The mechanical characteristics of steel are assessed through various tests that evaluate its strength, toughness, and flexibility. These tests include tension, torsion, impact, bending, and hardness assessments, each providing crucial information about steel's suitability for specific applications.
The tension test is fundamental for determining tensile strength. In this test, a steel specimen is stretched using a gripping device until it breaks. The data collected during this test are used...

Area of Science:

  • Materials Science
  • Metallurgy
  • Solidification Science

Background:

  • Invar alloy exhibits desirable properties like low thermal expansion.
  • Limited research exists on the rapid solidification of Invar alloy.
  • Undercooling is a critical parameter influencing solidification behavior.

Purpose of the Study:

  • Investigate Invar alloy solidification under varying undercooling conditions.
  • Analyze the effects of rapid solidification on microstructure and properties.
  • Determine the influence of undercooling on lattice constant and solid solubility.

Main Methods:

  • Employing glass melt-flux techniques for rapid solidification.
  • Achieving high undercooling levels (up to ΔT = 231 K).
  • Analyzing thermal history, microstructure, hardness, grain number, and density via XRD and microscopy.

Main Results:

  • Increased solidification undercooling led to a leftward shift in XRD peaks, indicating increased lattice constant and solid solubility.
  • Microstructure evolved from large dendrites to fine equiaxed grains with rising undercooling.
  • Hardness and grain number increased with undercooling, but plateaued beyond ΔT ≥ 181 K.

Conclusions:

  • Rapid solidification via undercooling significantly alters Invar alloy's microstructure and properties.
  • Enhanced solid solubility and grain refinement are observed with increasing undercooling.
  • A critical undercooling threshold exists beyond which further increases do not enhance grain number or hardness.
