EMATs for Science and Industry
Author: Masahiko Hirao
Publisher: Springer Science & Business Media
ISBN: 9781402074943
Category : Science
Languages : en
Pages : 388
Book Description
EMATs for Science and Industry comprises the physical principles of electromagnetic acoustic transducers (EMATs) and the applications to scientific and industrial ultrasonic measurements on materials. The text is arranged in four parts: -PART I is intended to be a self-contained description of the basic elements of coupling mechanism along with practical designing of EMATs for various purposes. There are several implementations to compensate for the low transfer efficiency of the EMATs. Useful tips to make an EMAT are also presented. -PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of contactless nature of EMATs and is the most successful amplification mechanism for precise velocity and attenuation measurements. -PART III applies EMAR to studying the physical acoustics. New measurements emerged on three major subjects; in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, and acoustic nonlinearity evolution. -PART IV deals with a variety of individual topics encountered in industrial applications, for which the EMATs are believed to the best solutions. The authors' work in this area has shown Electromagnetic acoustic resonance (EMAR) to be applicable not only to the acoustoelastic stress measurements, but also to many other nondestructive evaluation issues, including the determination of attenuation in solids. Noncontact measurement with high enough signal intensity was striking. Basic preconditions of theoretical approaches were realized by eliminating artifacts caused by the contact transducers. EMAR thus illuminated antiquated theories, which were accepted to be of little use or limited to qualitative interpretation of observations. It also uncovered interesting phenomena. Continuous monitoring of attenuation and acoustic nonlinearity resulted in the detection of ongoing microstructure evolutions in deforming or fatiguing metals. The aim of this book is to provide practical answers to the needs of ultrasonic measurements as well as an understanding of a novel methodology.

Electromagnetic Acoustic Transducers
Author: Masahiko Hirao
Publisher: Springer
ISBN: 443156036X
Category : Technology & Engineering
Languages : en
Pages : 382
Book Description
This second edition provides comprehensive information on electromagnetic acoustic transducers (EMATs), from the theory and physical principles of EMATs to the construction of systems and their applications to scientific and industrial ultrasonic measurements on materials. The original version has been complemented with selected ideas on ultrasonic measurement that have emerged since the first edition was released. The book is divided into four parts: PART I offers a self-contained description of the basic elements of coupling mechanisms along with the practical designing of EMATs for various purposes. Several implementations to compensate for EMATs’ low transfer efficiency are provided, along with useful tips on how to make an EMAT. PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of EMATs’ contactless nature and is the most successful amplification mechanism for precise measurements of velocity and attenuation. PART III applies EMAR to studying physical acoustics. New measurements have emerged with regard to four major subjects: in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, pointwise elasticity mapping (RUM), and acoustic nonlinearity evolution. PART IV deals with a variety of individual issues encountered in industrial applications, for which the EMATs are believed to be the best solutions. This is proven by a number of field applications.

EMAT (Electromagnetic-Acoustic Transducer) System for Ultrasonic Velocity
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages : 45
Book Description
An EMAT system has been designed and constructed which can be used for wall thickness measurements on steel tubes with surface temperatures up to 650 C and for measurements of residual stress near to the inner surface of a 120 mm gun barrel. The system consists of an EMUS (Electromagnetic-Ultrasonic) transmitter/receiver instrument, a high temperature Electromagnetic-Acoustic Transducer (EMAT) for wall thickness measurements with normally incident shear waves using the pulse-echo-technique and a device consisting of one transmitting EMAT and two receiving EMATs which are collinearly integrated into a mechanical support for the transduction of Rayleigh waves that are travelling along the circumferential direction on the inner surface of a 120 mm gun tube.

Sensors for Ultrasonic NDT in Harsh Environments
Author: Anthony N Sinclair
Publisher: MDPI
ISBN: 3039284223
Category : Technology & Engineering
Languages : en
Pages : 120
Book Description
In this Special Issue of Sensors, seven peer-reviewed manuscripts appear on the topic of ultrasonic transducer design and operation in harsh environments: elevated temperature, high gamma and neutron radiation fields, or the presence of aggressive chemicals. Motivations for these research and development projects are strongly focused on nuclear power plant inspections (particularly liquid-sodium cooled reactors), and nondestructive testing of high-temperature piping installations. It is anticipated that extensive use of permanently mounted robust transducers for in-service monitoring of petrochemical plants and power generations stations; quality control in manufacturing plants; and primary and secondary process monitoring in the fabrication of engineering materials will soon be made.
