Q1: Annealing of metal does notA precede its wire drawing.
B induce softness and removes stresses & dissolved gases.
C refine the crystalline structure & produce a definite microstructure.
D alter toughness, ductility and magnetic & electrical or other physical properties.
ANS:A - precede its wire drawing. Annealing of metal does not alter toughness, ductility, and magnetic, electrical, or other physical properties. Annealing is a heat treatment process used to induce softness, relieve internal stresses, and refine the microstructure of a metal. During annealing, the metal is heated to a specific temperature and then slowly cooled to allow for controlled recrystallization and grain growth. This process helps to improve the material's formability, machinability, and mechanical properties. However, while annealing can significantly affect the mechanical properties of a metal by making it softer and more ductile, it does not alter properties such as toughness, magnetic properties, or electrical conductivity. These properties are primarily determined by the chemical composition and crystal structure of the metal, which are not significantly affected by annealing. In summary, annealing of metal induces softness, removes stresses and dissolved gases, and refines the crystalline structure to produce a specific microstructure. However, it does not alter properties such as toughness, ductility, and magnetic, electrical, or other physical properties. |
