Metallographic Replication

Creep is a major cause of material degradation and cracking in plant components – steam piping, boiler headers, turbine casings, valves, etc. – that operate at high temperature and pressure. From the initial onset of creep, it progresses into creep crack development and finally creep crack growth. Using the metallographic replication techniques, RAE can evaluate the material surface microstructure and assess the creep damage that may be developing prior to catastrophic failure. Using past history and quantitative evaluation of the creep damage, a life prediction can be made for certain components. The replication technique can also be used to identify other material degradation caused by improper heating – embrittlement, graphitization and microstructural decomposition.
