RECORDS & PRESERVES INFORMATION WITH IN-SITU REPLICA METALLOGRAPHY
Replication Metallography is a non-destructive sampling procedure which studies materials’ structure by examining specially prepared and etched surfaces. It helps record and preserves the topography of a metallographic specimen as a negative relief on a plastic film.
For subsequent analysis, the microstructural replica can be examined using a light microscope or Scanning Electron Microscope (SEM).
For the construction and operation of a plant, a technical facility or equipment, the characteristics and quality of the materials used play an important role and need to be considered. In any situation, materials can change over time. Therefore, manufacturers and operators must be informed of the strength, quality and remaining lifetime of the materials they are using and warn of potential or existing damage.
Professional Testing Services analyse damage in a structure or estimate the remaining lifetime of a component or equipment. Our experienced inspection team will identify materials used in old structures that are needed to solve maintenance issues and problems. Our testing experts can conduct a non-destructive microstructure analysis using the replica testing technique and provide you with a direct evaluation of creep damage.
APPLICATION OF IN-SITU REPLICA METALLOGRAPHY
To characterise the Present microstructural condition of a material that has operated at high temperatures on the short-term or the long-term overheating cycles.
To study and characterise any surface or sub-surface cracking (in situ) before they are ground, excavated or cut out.
To identify micros structurally the cause of failure of welded and other types of components.
TALK TO US TODAY
Metallographic replication is essential for ensuring plant operation continuity and the safety of operating personnel and the public. As requested, our expert technical team can offer in-field interpretation of replicas to support outage schedules. If microstructure examination is not sufficient on the surface alone, our metallurgist team can take samples for tests on (partial) cross-sections.
