Vedclass · Answer

(D) Heat treatment involves heating steel to a specific temperature and then cooling it at a controlled rate. This process changes the arrangement of atoms in the crystal lattice (e.g.,from austenite to martensite or pearlite),which significantly alters the mechanical properties of the steel such as hardness,ductility,and strength. Therefore,the correct option is $D$.

Heat treatment alters the properties of steel due to:
