What is stress decay cracking? What are the characteristics and rules?
Most titanium alloys used in the chemical industry are not susceptible to stress corrosion cracking. Stress corrosion cracking may occur only in such special media as alcohol, fuming nitric acid, halide aqueous solution of nitrogen tetroxide, liquid metal calcium, and mercury. Industrial practice has proved that the actual occurrence of stress corrosion cracking accidents is far less than the stress corrosion sensitivity found in laboratory.
Stress corrosion sensitivity is related to the composition of the medium,PH value, potential, temperature and even the viscosity of the medium. Adding halogen ions improves the sensitivity of stress corrosion, and increases with the increase of ion concentration. The cracking rate can be accelerated by increasing temperature and decreasing viscosity
