"Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by an optical microscope above 25× magnification."
The structure of materials at the microscopic level, including crystal defects, and grain boundaries.
Crystal structure: Understanding the basic structure of crystals and how they influence the physical properties of materials.
Defects in crystals: Types of defects that can occur in crystals and their impact on material properties.
Grain boundaries: Understanding the structure and behavior of grain boundaries and their impact on mechanical properties.
Phase diagrams: Understanding how the composition and temperature of a material affect its microstructure and properties.
Alloying: The process of combining two or more metals to create a new material with properties that are different from the constituent metals.
Heat treatment: Understanding the impact of heating and cooling on the microstructure and properties of a material.
Deformation: Understanding how materials deform under stress and how this affects their microstructure.
Texture: Understanding the orientation of crystal grains within a material and its impact on physical properties.
Microscopy: Different techniques and equipment used for examining and characterizing microstructures.
Mechanical testing: Testing methods used to measure the mechanical properties of materials, including strength, ductility, and toughness.
Phase transformations: Understanding the different phases that a material can undergo and how they affect its properties.
Surface engineering: Techniques used to modify the surface properties of materials, including surface roughness and hardness.
Corrosion: Understanding the different types of corrosion and how microstructure can affect a material's susceptibility to corrosion.
Nanomaterials: Understanding the unique properties and behavior of materials at the nanoscale and their potential applications.
Biomaterials: Understanding the behavior and properties of materials used in medical implants and devices.
Polymers: Understanding the structure and behavior of polymers and their applications in different industries.
Computational materials science: Using computer simulations to model and predict the behavior of materials at the microscale.
Additive manufacturing: Understanding the use of 3D printing technology to create complex microstructures and materials.
Grain Structure: It is the arrangement of grains or crystalline size components that make up the solid material.
Phase Structure: It is the amount, shape, and distribution of different phases present in the material. In metals, the phases are typically solid solutions, intermetallic compounds, and amorphous phases.
Defect Structure: It is the distribution of point defects (vacancies, interstitials), line defects (dislocations), and planar defects (grain boundaries, interfaces, stacking faults) in the crystalline material.
Texture Structure: It is the arrangement of the crystal orientations in the material, which can cause anisotropy in the mechanical, magnetic, and electrical properties.
Lamellar Structure: It is the arrangement of thin layers or lamellae of different materials in a composite material, such as a metal matrix composite or a ceramic matrix composite.
Porosity Structure: It is the distribution and shape of voids or pores in the material, which can affect the strength, stiffness, and thermal properties.
Interface Structure: It is the structure and composition of the interface between two dissimilar materials, such as a metal-ceramic interface or a metal-polymer interface.
Amorphous Structure: It is the lack of long-range order or crystallinity in a material, which is common in glasses, polymers, and some metals.
Martensitic Structure: It is a specific crystal structure that forms when a metal is rapidly cooled from high temperatures, resulting in a very hard and brittle material.
Twin Structure: It is the arrangement of orientationally related regions or twins in a crystalline material, which can affect the deformation behavior and mechanical properties.
"The microstructure of a material can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behavior, or wear resistance."
"The microstructure of a material (such as metals, polymers, ceramics, or composites) can strongly influence physical properties..."
"These properties in turn govern the application of these materials in industrial practice."

"The structure in which individual atoms are arranged is known as the crystal structure."
"The nanostructure of biological specimens is referred to as ultrastructure."
"A microstructure’s influence on the mechanical and physical properties of a material is primarily governed by the different defects present or absent in the structure."
"The primary ones are the pores."
"Even if those pores play a very important role in the definition of the characteristics of a material..."
