  3. Grain boundary strengthening - Wikipedia

    en.wikipedia.org/wiki/Grain_boundary_strengthening

    Grain boundary engineering involves manipulating the grain boundary structure and energy to enhance mechanical properties. By controlling the interfacial energy, it is possible to engineer materials with desirable grain boundary characteristics, such as increased interfacial area, higher grain boundary density, or specific grain boundary types ...

    en.wikipedia.org/wiki/Unified_Soil...

    The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):

    en.wikipedia.org/wiki/Subgrain_rotation_re...

    In metallurgy, materials science and structural geology, subgrain rotation recrystallization is recognized as an important mechanism for dynamic recrystallisation.It involves the rotation of initially low-angle sub-grain boundaries until the mismatch between the crystal lattices across the boundary is sufficient for them to be regarded as grain boundaries.

  6. Grain boundary - Wikipedia

    en.wikipedia.org/wiki/Grain_boundary

    In materials science, a grain boundary is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are two-dimensional defects in the crystal structure , and tend to decrease the electrical and thermal conductivity of the material.

    In materials science, segregation is the enrichment of atoms, ions, or molecules at a microscopic region in a materials system. While the terms segregation and adsorption are essentially synonymous, in practice, segregation is often used to describe the partitioning of molecular constituents to defects from solid solutions, [1] whereas adsorption is generally used to describe such partitioning ...

  8. Grain boundary sliding - Wikipedia

    en.wikipedia.org/wiki/Grain_boundary_sliding

    Grain boundary sliding (GBS) is a material deformation mechanism where grains slide against each other. This occurs in polycrystalline material under external stress at high homologous temperature (above ~0.4 [1]) and low strain rate and is intertwined with creep.

    Palette stacked autoclaved aerated concrete blocks. Autoclaved aerated concrete (AAC) is a lightweight, prefabricated concrete building material. Developed initially in the mid-1920s, it has expanded into widespread use. [citation needed] It is most suitable for producing a lightweight or most cost-effective alternative to traditional concrete ...
