Carbide shape, size and relative area in steels and superalloys can indicate the current condition; aging and previous heat treatments performed and therefor is one of the critical features that need to be evaluated. TEServices captures and reports the shape, location, maximum size (µm), average size (µm), and relative average area (%) of a base … Continue reading Critical Features That Need to be Evaluated →
Sometimes, the condition needs to be assessed without removal of a sample. An example of this is when determining the extent of compressor blade erosion or impact damage. Using replica technology and a 3D digital microscope TEServices can evaluate compressor blade erosion or impact damage without removal of the blades or in most instances even … Continue reading Determining the Extent of Compressor Blade Erosion or Impact Damage →
EPRI has awarded TEServices to manage the Advanced TBC Rainbow Testing for the durability of conventional and advanced TBC on 7F .03 Stage 1 Buckets (S1B) under severe circumstances (steam injected and higher firing temperature) which is comparable to low carbon operational conditions. OEM’s, alternative repair and coating facilities will be invited to participate in … Continue reading EPRI Has Awarded TEServices to Manage the Advanced TBC Rainbow Testing →
Prior to committing to the cost for repair TEServices can perform metallurgical evaluations including gamma prime analysis to figure out the progress of deterioration of the base material and verify the effect of regenerative heat treatments and review the possibility of extension of operation life.
This month, EPRI has awarded TEServices a study of metallurgical and mechanical properties for MGA 1400 DS in the new, aged at 900°C, 1000°C and 4000°C for 1000 hours and rejuvenation heat treated conditions. Stress rupture, low cycle fatigue (LCF) and a combination of stress rupture and LCF will be tested on new, aged and … Continue reading EPRI Has Awarded TEServices a Study →
TEServices performs First Article Inspection (FAI) or qualification for end-users, OEM’s, repair and coating facilities. We can evaluate and qualify stripping, welding, brazing and coating processes using provided specifications or our own internal specifications. A typical coating qualification reviews the coating chemistry and thickness. TEServices adds to this typical qualification by also evaluating: interface, un-melted … Continue reading First Article Inspection (FAI) →
When non-destructive evaluations give reasons for concern or when there are other concerns, such as over-firing the turbine or running beyond OEM recommended life, TEServices can provide you with a more comprehensive evaluation. Life assessment combines metallurgical evaluation at critical locations with mechanical testing. Stress rupture testing reveals the true strength of the material at … Continue reading More Comprehensive Evaluation →
Extended F7FA .04 S1B single crystal (Rene N4 – N5) testing program to evaluate low temperature heat treatments. Since 2017, the consortium of EPRI, MD&A, Sulzer, University of Florida and TEServices have been investigating repair of the GE S1B single crystal alloys. Baseline, aged, post rejuvenating heat treatments, metallurgical properties, mechanical properties, welding, coating and … Continue reading Extended F7FA .04 S1B Single Crystal (Rene N4 – N5) Testing Program →
TEServices’ metallurgical lab is still operating as normal with COVID safety measures in place. Furthermore, we continue to support our customers with vendor verification including offsite inspections through video / audio conferencing.
When one of your components fails, understanding why may become critical. Not only to be able to recoup some of the losses but also to avoid this type of failure in the future. TEServices not only has the equipment such as visual, digital (Keyence) and scanning electron microscopes, and metallurgical expertise, but also the component … Continue reading Failure Analysis →
