HEAT TREATMENT PROCESSES Contd... INTERRUPTED QUENCHING ✔ The quenching i.e., rapid cooling mechanism discussed in Section 2.4 has it own disadvantages. Some of the disadvantages of continuous rapid cooling are: 1. Setting up severe quenching stresses, 2. Warping or distorting the object, and 3. Promoting crack formation in the steel. These undesirable effects may develop during uneven cooling of the heat-treated material. ✔ In order to overcome the disadvantages of continuous quench- ing, a modified quenching procedure known as interrupted quenching is usually used. ✔ Two forms of interrupted quenching are: 1. Martempering, and 2. Austempering.
