MICROSTRUCTURAL EXAMINATIONS OF SURFACE/SUBSURFACE DAMAGE
Aerospace research has shown that the subtle subsurface damage caused by out of tolerance machining conditions creates sites where fatigue cracking can start, leading to component failure. IMR’s labs in NY and Singapore specialize in evaluating machined surfaces for evidence of damage from Aggressive and Abusive machining conditions.
During the manufacturing process, improper material feeds, speeds, or dulled tooling can leave high stress areas where cracks can initiate. These very small defects can result in distortion in the microstructure, which can lead to failure of the part or component, resulting in premature repair or replacement.
IMR Test Labs has the ability to perform the high-precision sample preparation needed to be able to resolve the subtle near-surface distortion and damage characteristics of non-optimal machining conditions, as well as a number of highly trained and experienced metallographers in our New York and Singapore laboratories. This allows us to meet your schedule needs even on large programs.
Some of the defects can include
- Laps and tears
- Grain distortion
- White Layer
- Strain Lines
Manufacturers of critical components such as disks, blisks, blades and shrouds rely on IMR Test Labs. For more information on IMR's microstructural analysis capabilities, click here to request a quote, or click the button below.
