Materials Characterization for Process Control and Product Confromity

Nondestructive testing (NDT) is used to examine the ability of materials and components to withstand loads. Two features of NDT are defect inspection and materials characterization. Because of the increasing ability to manufacture materials and products "defect free" there is less need for defect-oriented NDT but an increasing need for materials characterization. This book is the first comprehensive work on materials characterization, presenting the state of the art and practical applications. Materials characterization is used during production, operations, service intervals, or after repairs. Materials are used to withstand mechanical, thermal, chemical, and irradiation loads-or a combination thereof. The ability to withstand these loads is essentially a function of parameters like chemical composition, microstructure, macrostructure, residual stresses, and materials properties. The physical background of NDT is presented along with its different methods. Ultrasonics, electromagnetics, and X-rays are treated with appropriate detail, while other methods such as acoustic emission, vibration analysis, optical, and thermal methods are also covered. The different methods of materials characterization are discussed following the goal parameters, from atomic to macroscopic dimensions. One of the practical features of the book is the presentation of real world applications. On-line process control and condition monitoring are discussed, as well as off-line applications for materials characterization after production and after operation.
Non-destructive Materials Characterization and Evaluation

This book is devoted to non-destructive materials characterization (NDMC) using different non-destructive evaluation techniques. It presents theoretical basis, physical understanding, and technological developments in the field of NDMC with suitable examples for engineering and materials science applications. It is written for engineers and researchers in R&D, design, production, quality assurance, and non-destructive testing and evaluation. The relevance of NDMC is to achieve higher reliability, safety, and productivity for monitoring production processes and also for in-service inspections for detection of degradations, which are often precursors of macro-defects and failure of components. Ultrasonic, magnetic, electromagnetic and X-rays based NDMC techniques are discussed in detail with brief discussions on electron and positron based techniques.

Materials Characterization Using Nondestructive Evaluation (NDE) Methods discusses NDT methods and how they are highly desirable for both long-term monitoring and short-term assessment of materials, providing crucial early warning that the fatigue life of a material has elapsed, thus helping to prevent service failures. Materials Characterization Using Nondestructive Evaluation (NDE) Methods gives an overview of established and new NDT techniques for the characterization of materials, with a focus on materials used in the automotive, aerospace, power plants, and infrastructure construction industries. Each chapter focuses on a different NDT technique and indicates the potential of the method by selected examples of applications. Methods covered include scanning and transmission electron microscopy, X-ray microtomography and diffraction, ultrasonic, electromagnetic, microwave, and hybrid techniques. The authors review both the determination of microstructure properties, including phase content and grain size, and the determination of mechanical properties, such as hardness, toughness, yield strength, texture, and residual stress. - Gives an overview of established and new NDT techniques, including scanning and transmission electron microscopy, X-ray microtomography and diffraction, ultrasonic, electromagnetic, microwave, and hybrid techniques - Reviews the determination of microstructural and mechanical properties - Focuses on materials used in the automotive, aerospace, power plants, and infrastructure construction industries - Serves as a highly desirable resource for both long-term monitoring and short-term assessment of materials
