Imaging of morphological and physicochemical changes occuring in the structure of austenitic steel due to the thermal sensitization
Dane BadawczeIn polycrystalline materials, grain boundaries are always where phenomena such as surface diffusion, sedimentation and corrosion occur. They have a significant impact on the macroscopic properties of the construction material [1]. In addition to inhomogeneities such as manganese sulphide inclusions formed during the metallurgical process, interfacial...
