Available in PDF, EPUB and Kindle. Book excerpt: This report is the technical summary of a 15-month study into the application of nondestructive test (NDT) methods to determine the mechanical properties of metal matrix composites. A number of NDT methods aimed at the direct evaluation of mechanical properties were developed. These methods were vibration tests, ultrasonic velocity and attenuation measurement, and acoustic emission. All methods gave very promising results and correlations and are potentially capable of development into industrial test systems. An analytic study of defect characterization in these materials indicates an inherently wide property scatter and indicates the theoretical effects of filament misalinement and filament breaks and of delamination. An industry survey was conducted and the general conclusions indicate a growing interest in complex shapes, which present no basic problems but require adaptation of instrumentation.

Available in PDF, EPUB and Kindle. Book excerpt: The basic objectives of this work were: to apply nondestructive evaluation techniques to metal matrix composites; to obtain base line data as to the ability of these techniques to locate, identify and quantify defects in these materials; to determine the effect of these defects on strength and stiffness; and to modify the techniques as required for application to specimens having geometries other than the flat tensile coupon. Several different nondestructive testing techniques have been considered for possible application to metal matrix composites. A description of these is given in the following pages. Some of these methods have been applied during the past year to Al/Fp fiber composites while others have been investigated in a preliminary fashion in order to determine potential problem areas that will need to be solved for proper application in the coming year.

This book was released on 2013-03-14 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possibility of nondestructively characterizing the microstruc ture, morphology or mechanical properties of materials is certainly a fascinating subject. In principle, such techniques can be used at all stages of a material's life - from the early stages of processing, to the end of a structural component's useful life. Interest in the subject thus arises not only from a purely scientific point of view but is also strongly motivated by economic pressures to improve productivity and quality in manufacturing, to insure the reliability and extend the life of existing structures. The present volume represents the edited papers presented at the Second International Symposium on the Nondestructive Characterization of Materials, held in Montreal, Canada, July 21-23, 1986. The Proceedings are divided into eight sections, which reflect the multidisciplinary nature of characterizing materials nondestructively: Polymers and Composites, Ceramics and Powder Metallurgy, Metals, Layered Structures/Adhesive Bonds/Welding, Degradation/Aging, Texture/ Anisotropy, Stress, and New Techniques. Invited papers by R. Hadcock of Grumman Aircraft Systems, R. Cannon of Rutgers University, H. Yada of Nippon Steel and R. Bridenbaugh of Alcoa review respectively the processing of polymer matrix composites, ceramics, steel and aluminum, emphasizing the need for material property sensors to improve process and quality control. Two other invited papers, one by A. Wedgwood of Harwell and the other by P. Holler of the IzFP in Saarbrucken review state of the art techniques to characterize particulate matter and metals respectively.

Available in PDF, EPUB and Kindle. Book excerpt: In this era of technological progress and given the need for welfare and safety, everything that is manufactured and maintained must comply with such needs. We would all like to live in a safe house that will not collapse on us. We would all like to walk on a safe road and never see a chasm open in front of us. We would all like to cross a bridge and reach the other side safely. We all would like to feel safe and secure when taking a plane, ship, train, or using any equipment. All this may be possible with the adoption of adequate manufacturing processes, with non-destructive inspection of final parts and monitoring during the in-service life of components. Above all, maintenance should be imperative. This requires effective non-destructive testing techniques and procedures. This Special Issue is a collection of some of the latest research in these areas, aiming to highlight new ideas and ways to deal with challenging issues worldwide. Different types of materials and structures are considered, different non-destructive testing techniques are employed with new approaches for data treatment proposed as well as numerical simulations. This can serve as food for thought for the community involved in the inspection of materials and structures as well as condition monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to apply nondestructive evaluation (NDE) methods to identify potentially harmful casting defects in FP/magnesium composites; establish detectability and reproducibility limits of NDE applied to FP/magnesium composites; and establish relationships between casting defects and failure modes of FP/magnesium composites. The material investigated was ZE41A magnesium alloy reinforced with FP (aluminum oxide) fibers. The 27 coupons (four coupons each of five flaw types and seven coupons from a related program were evaluated using ultrasonic scanning, wave propagation velocity, and wave attenuation inspection techniques. The coupons evaluated were 12.7 cm (5 in.) long x 3.8 cm (1.5 in.) wide x 0.6 cm (0.25 in.) thick, with a fiber volume fraction of 0.50. After the detectability and reproducibility NDE inspections, tensile and/or bend specimens were machined from the parent coupons, strain gaged, and statically loaded to failure. Micrographs were made of the fracture surfaces for comparison with the NDE records. It was found that ultrasonic scanning using a 20 MHz compression wave, focused transducer operated in the pulse-echo mode generating an analog C-scan provided 100% detectability and reproducibility of the intentionally flawed coupons. Keywords: Metal matrix composites; Nondestructive testing; Nondestructive testing; Magnesium; Fiber reinforced composites; Castings; and Aluminum oxides.

Available in PDF, EPUB and Kindle. Book excerpt: Residual stresses are a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, light-weight materials such as composites and their wide range of applications in the aerospace and automotive industries, in civil infrastructure and in sporting applications, it is critical that the residual stresses of composite materials are understood and measured correctly. The first part of this important book reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. Various mathematical (analytical and numerical) methods for calculation of residual stresses in composite materials are also presented. Chapters in the first section of the book discuss the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses residual stresses in polymer matrix, metal-matrix and a range of other types of composites. Moreover, the addition of nanoparticles to the matrix of polymeric composites as a new technique for reduction of residual stresses is discussed. Residual stresses in composite materials provides a comprehensive overview of this important topic, and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine and sporting industries.

Book excerpt: Samples of aluminum metal matrix composites (AlMMCs) have been examined with nondestructive evaluation techniques. A literature search identified ultrasonic C-scans as one of the most promising techniques, and this approach was used along with an eddy-current based approach, Meandering Winding Magnetometer (MWM), that also had some potential usefulness for flaw detection. Samples with known flaws were first investigated to ascertain the sensitivity of the equipment. Subsequent tests were performed on samples obtained from the University of Delaware. The findings were that both ultrasonics and MWM could detect gross flaws (cracks, delaminations, lack of matrix infusion, etc.) but that more subtle defects such as fiber waviness could not be detected unequivocally. Since fiber volume content determines to a large extent the strength of that AlMMC, a quantitative relationship between fiber volume content and the sonic velocity was developed. It was also noted that as fiber volume content increased, the ultrasonic signal attenuation increased. High signal attenuation due to high fiber volume content in some of the earlier ultrasonic scans led to a misinterpretation of those scans that was subsequently corrected.
