Quantitative metallography as a tool for predicting the impact strength of CF 8M stainless steel

  • Published:
Journal of Materials for Energy Systems

Abstract

Charpy impact tests and quantitative metallography were performed on CF 8M stainless steel specimens which had been aged at 750 °C for times ranging from 1.2 minutes to 12 hours. Relationships between impact energy and microstructural parameters were explored and it was found that the loss in impact strength during aging was related to the fraction of ferrite-austenite interfacial area covered with intermetallic precipitates. The loss in impact strength was also related to the proportion of ferrite volume transformed.
