Study of stress corrosion cracking initiation of high alloy materials
Original language description
In the contribution is studied the initiation and propagation of stress corrosion cracking of high alloy materials. The stainless steels and related alloys with sufficient resistance to a general corrosion can be susceptible to a localized corrosion (pitting, SCC, intergranular corrosion) in certain environment under specific conditions. The Drop Evaporation Test (DET) was developed for study of stainless materials resistance to stress corrosion cracking (SCC) at elevated temperatures 200 - 300 °C underconstant external load using a chloride containing water solution. The initiation and propagation of short cracks as well as pits were observed during the test. The crack initiation and/or propagation can be influenced by cyclic thermal stresses, when the diluted NaCl water solution drops cool down the hot sample. The coordinates measurement of microscopic pits and sharp corrosion crack tips by the travelling microscope method allowed to derrive the crack growth lengths and rates of sho
