A model-assisted probability of detection (MAPOD) validation of Process Compensated Resonance Testing (PCRT) inspection for creep deformation is presented. The PCRT inspection was trained [...]
Titanium alloys used by the aerospace industry, like Ti-64 or Ti-6242, with Microtexture Regions (MTR’s) have been shown to exhibit significantly reduced dwell fatigue lifetimes. Over the last [...]
A case study is presented evaluating uncertainty in Resonance Ultrasound Spectroscopy (RUS) inversion for a single crystal (SX) Ni-based superalloy Mar-M247 cylindrical dog-bone specimens. A [...]
Process compensated resonant testing (PCRT) is a full body nondestructive evaluation (NDE) method that measures the resonance frequencies of a part and correlates them to the part’s material [...]
Process Compensated Resonant Testing (PCRT) is a full-body nondestructive testing (NDT) method that measures the resonance frequencies of a part and correlates them to the part’s material and/or [...]
Presentation by Pratt & Whitney Canada to A4A NDT Forum describing a P&WC Case Study for application of PCRT. "P&WC was able to rapidly implement a PCRT inspection process that met the [...]
Presentation by Delta TechOps to A4A NDT Forum describing Delta's success with PCRT for multiple turbine blade applications. "Simultaneous increase in reliability with cost savings!"
The objective of this paper is to investigate Resonance Ultrasound Spectroscopy (RUS) measurement models to more precisely connect changes in the resonance frequencies of nickel-based super-alloy [...]
