Corrosion fatigue under the load of low frequency and bigh mean stress has been generally defined as stress corrosion fatigue(SCF).It is a specific failure process due to the inter- action between stress corrosion cracking(SCC) and corrsion fatigue(CF),the effects of which on fracture characteristics,including crack initiation and propagation.service life and cracking mode have not been investigated systematically.The purpose of this pa- per was to study the environment-sensitive fracture behaviour of OCr18Ni9Ti austenitic stainless steel under the load of different fiequencies and high mean stress in boiling MgCl_2 solution.The interaction between SCC and CF would be emphasized.

A study was carried out in order to investigate the effect of contaminants and meteorological variables on the rust layer of carbon steel exposed in Shenyang urban atmosphere. Seven kinds of contaminants and twelve kinds of meteorological parameters were also registered in order to correlate the data with respect to corrosion rate and the stepwise multiple regression analysis was carried out in order to obtain the best regression model. The sum of rainfall time as well as sunshine time and the concentration of H(2)S could stimulate initial atmospheric corrosion of carbon steel. The initial atmospheric corrosion kinetics of carbon steel was observed to follow the cubic equation. The corrosion products were analyzed by XRD and the transformation of phases in different periods was discussed.
