The method of detecting dislocations by forming a visible precipitate along the dislocation lines is known as ____________ the small amount of impurity is intensely added to form the precipitate after heat treatment. Correct Answer decoration

The Decoration technique was first used by Hedges and Mitchell’ to decorate dislocations in AgBr with photolytic silver. It has been used in many ionic crystals, such as AgCI, NaC1, KC1, and CaF2.
