👉 Macrostructure refers to the characteristic structure of a material, such as its grain structure, crystal structure, or physical properties. It is a more detailed and complex aspect than microstructure, which describes the atomic arrangement within a material at a particular location within a crystal lattice. Macrostructures can be classified into various types based on their functional characteristics. For example, materials with high strength and toughness are typically characterized by macrostructures that exhibit high strain-hardness. Other examples include materials with good electrical conductivity or thermal
