The final chapters on Heat Treatment Defects are gold for viva voce (oral exams). Memorize the causes and remedies for:
Heat treatment is defined as an operation or combination of operations involving heating and cooling of a metal/alloy in the solid state. The objective is simple yet profound: to obtain desirable conditions or properties. A quality text on this subject, as expected from Rajan’s work, usually begins by dispelling the myth that heat treatment is merely "cooking" metal. It introduces the concept of **Phase heat treatment t.v. rajan pdf
