摘要
Microfractographical features of corrosion fatigue process of 12 Cr stainless steel turbine blade material are described. The emphasis is focussed upon the initiation and growth of corrosion pits in corrosion fatigue crack initiation process. A quantitative analyzed example of corrosion pit by use of recent developed image analyzing technology is also touched in brief. © 1990, The Iron and Steel Institute of Japan. All rights reserved.
