Abstract

In the wide environment sensitive cracking research area of the nuclear power plant components and materials, corrosion fatigue (CF) and stress corrosion cracking (SCC) of pressure vessel steels and stainless steels have been studied at the Technical Research Centre of Finland (VTT) during several years. CF studies have been concentrated on the pressure vessel steels, but ill the future tests also CF of austenitic stainless steels is studied. SCC studies have covered both materials. In addition, there have been special interests on other materials, such as high strength nickel-base alloys, low pressure rotor steels, copper, titanium and titanium alloys. The cracking phenomena in all these materials have also been considered from the mechanistic point of view. An advanced autoclave testing facility with high temperature reference electrodes and pH-sensors has been developed for these studies.
