On-Site Microstructure Evaluation Without Component Removal

In-Situ Metallography Replica (IMR) is a non-destructive technique used to examine the microstructure of metal surfaces directly at the site without dismantling the component. The process involves selecting a location, mechanical grinding and polishing, followed by electrolytic or chemical etching, and capturing a replica of the surface for microscopic analysis. The portable IMR kit includes a variable-speed grinder, electrolytic etcher/polisher, microscope, and various consumables like polishing papers, diamond paste, solvents, and replica films. This technique is essential for assessing material degradation, creep, phase transformation, and structural integrity in critical components.

Applications

IMR is used for on-site microstructural evaluation of components like boiler tubes, pressure vessels, pipelines, and turbine parts. It is widely applied in power plants, refineries, and process industries to assess material condition without dismantling or disrupting operations.

Benefits

IMR allows quick, non-destructive examination of metal surfaces, helping detect early signs of creep, corrosion, phase changes, or grain structure alterations. It supports preventive maintenance, extends equipment life, and aids in life assessment studies with minimal downtime.

On-Site Microstructure Analysis for Critical Asset Health

Arudra’s In-Situ Metallography Replica (IMR) services provide a fast, non-destructive method to assess the microstructural condition of critical components directly on-site.
Using portable equipment and replica techniques, we examine surfaces of boilers, pressure vessels, turbines, and piping without dismantling or interrupting operations. IMR helps detect early signs of creep, corrosion, grain structure changes, and phase transformations—crucial for preventive maintenance and residual life assessment. Arudra’s experienced team ensures accurate surface preparation, replication, and microscopic analysis, delivering clear insights for informed decision-making and continued safe operation of assets.
