Grain structure of a metal
WebApr 4, 2024 · Grain structure of a solid is an arrangement of differently oriented grains, surrounded by grain boundaries. Formation of a boundary between two grains may be imagined as a result of rotation of crystal lattice of one of them about a specific axis. What is fine grain structure? Fine grain steels have good cold formability and toughness. WebThe recrystallization temperature is that temperature at which the crystal lattice structure of the metal becomes reoriented. Consequently, the metal becomes more workable and ductile. ... since plastic flow can induce phase transformations and alterations in grain structures which can markedly affect mechanical properties of the material ...
