Nondestructive Evaluation of Low Temperature Thermal Embrittlement in Duplex Stainless Steels: Review and Comparison of Multiple Techniques

Alberto Ruiz, Jin-Yeon Kim

This paper investigates nondestructive evaluation (NDE) for assessing low‑temperature thermal embrittlement (also known as the 475°C embrittlement) in duplex stainless steel (DSS) alloys. Current assessments rely primarily on destructive methods such as the Charpy test and double‑loop electrochemical potentiokinetic reactivation (DL-EPR). To …

Experimental evaluation of non-collinear shear wave mixing to characterize interface nonlinearity

Hendrik M. Carius, Péter B. Nagy, Junzhen Wang, Jin-Yeon Kim et autres

In the search for techniques to distinguish between merely good and excellent bond conditions, linear reflection based methods are simple to apply, but their sensitivity decreases rapidly with increasing bond quality. As an alternative, this research reports on the experimental validation of …

Single-sided non-collinear shear wave mixing for material characterization

J. S. Wang, Hendrik M. Carius, Péter Nagy, Jin-Yeon Kim et autres

This Letter develops a single-sided non-collinear shear wave mixing technique for material characterization based on the phase-matching interface condition. Analytical modeling reveals that the interference between incident and reflected waves produces standing wave patterns whose interaction significantly enhances the mixed wave energy. …

Analytical and numerical modeling of non-collinear wave mixing due to material and interface nonlinearity

Junzhen Wang, Péter B. Nagy, Hendrik M. Carius, Jin-Yeon Kim et autres

Previous research established a nonlinear stiffness model for imperfect interfaces and analyzed non-collinear wave mixing at such interfaces for two incident shear waves. This study extends those results to encompass five possible non-collinear wave mixing modalities involving longitudinal and shear vertical waves, …

Detection of alkali-silica reaction within large-scale concrete by ultrasound non-collinear wave mixing

Jin-Yeon Kim, Caroline Fjeran, Lauren Stewart, Kimberly E. Kurtis et autres

Abstract Early detection of alkali-silica reaction (ASR) with nondestructive evaluation (NDE) is important for the monitoring of damage and assessment of repair performance, while effective NDE in large-scale reinforced concrete elements remains challenging. Nonlinear acoustic methods have shown promise for this application …

Evaluating effects of microstructure and porosity on elastic anisotropy of additively manufactured materials using ultrasonic techniques

Daniel Herburger, Jin-Yeon Kim, Nicholas Lark, Laurence J. Jacobs

The potential of additive manufacturing is often limited by qualification issues, particularly due to process defects such as lack-of-fusion porosity and highly anisotropic elastic properties. This research demonstrates the ability of ultrasonic measurement techniques to assess these elastic properties, process defects, and …
