Intergranular Corrosion Detection Using Electromagnetic Transducers for Ultrasonic Testing [PDF]
Archives of Metallurgy and Materials, 2020 The aim of this paper is to create a research methodology that allows a quick analysis of the structural state of high alloy austenitic steels using non-destructive ultrasonic tests, in contrast to destructive standard methods.

Signal enhancement of the in-plane and out-of-plane Rayleigh wave components [PDF]
, 2005 Several groups have reported an enhancement of the ultrasonic Rayleigh wave when scanning close to a surface-breaking defect in a metal sample. This enhancement may be explained as an interference effect where the waves passing directly between source ...

Phased electromagnetic acoustic transducer array for Rayleigh wave surface defect detection [PDF]
, 2020 A phased electromagnetic acoustic transducer (EMAT) array system has been developed for detection and characterisation of surface breaking defects. An array of four linear coils which are individually controlled are used to generate a Rayleigh wave.

Exploring Replica-Exchange Wang-Landau sampling in higher-dimensional parameter space [PDF]
, 2015 We considered a higher-dimensional extension for the replica-exchange Wang-Landau algorithm to perform a random walk in the energy and magnetization space of the two-dimensional Ising model.

Shear wave generation using a spiral electromagnetic acoustic transducer [PDF]
, 2006 A spiral electromagnetic acoustic transducer (EMAT) is efficient in eddy current generation and has been used for surface defect inspection using Rayleigh waves or thickness gauging based on plane waves in echo mode.

Defects Inspection in Wires by Nonlinear Ultrasonic-Guided Wave Generated by Electromagnetic Sensors
Applied Sciences, 2020 Steel wires are widely used as raw materials for spring valves in engines. Considering the quality and safety issues of their structure, there is a demand to develop nondestructive inspection approaches to detect initial damages in steel.

Supplier selection requires full transparency [PDF]
, 2010 In this paper, we highlight a number of problems arising with a commonly used supplier selection method: the weighted factor score method. We discuss the behavior of this method with respect to weighting, scaling issues, and relative scoring.
