Mitsubishi Heavy Industries - Development of precipitation simulation method for FGHAZ in mod.9Cr-1Mo steels

Project: Research project

Project Details


The major objective of this research is to develop a precipitation simulation method for mod.9Cr-1Mo martensitic (ASME Gr.91). Understanding pathways of microstructure degradation during high temperature and creep load is necessary to optimize service time of boilers as well as welds to opti-mize parameters during the manufacturing process. Material flux as the cause for microstructure degradation can be monitored by the observation of - Precipitation evolution during service - Evolution of dislocation density during service - Grain size and sub grain size evolution during service - Solid solution of atoms during service - Void formation during service
