Induction heating stress improvement

Fig. 3.49 for mechanical loads, that will force the unloading from A to C and a residual compressive stress will remain on the external surface. Alike point A any other element of material gone beyond yield point will rest in a residual stress state, which will be compressive on one side and tensile on the other, as shown in Fig. 3.68. This simple process is used in the most important thermo-mechanical treatment known as induction heating stress improvement (IHSl) developed in the 70s in the nuclear field to eliminate corrosion problems on sensitized stainless steel [66-69]. Its purpose is to eliminate tensile residual stress generated on the inner surface of a pipe made of austenitic stainless steels by a welding process.
