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 1997 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall program consisted of two distinct phases with objectives: Phase I Objective: To characterize the evolution of isothermal fatigue damage using nondestructive evaluation techniques and correlate this information with residual strength of the composite. Phase II Objective: To characterize and compare the evolution of damage due to creep and TMF fatigue of metal matrix composites (SCS-6/TI-6A1-4V manufactured by Textron Specialty Materials) using nondestructive evaluation techniques and thereby derive an 'inefficiency factor' for damage accumulation under in-phase thermomechanical fatigue (IP-TMF). Phase I Results: The first phase of the program concluded that the usefulness of ultrasonic nondestructive evaluation to assess fatigue damage in a 06 Sigma-1240/Ti-6242 composites has been demonstrated through correlation of immersion and in situ ultrasonic data with residual tensile strength. Immersion surface wave scanning proved to be one of the most promising methods for correlating fatigue damage with the residual tensile strength for the composite used in this study. This study demonstrated that in situ nondestructive ultrasonic longitudinal wave and acoustic emission techniques can monitor the onset and accumulation of damage produced by either sustained loading or in-phased thermomechanical fatigue loading in a titanium matrix composite.

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.

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.

This book was released on 2012-12-06 with total page 2093 pages. Available in PDF, EPUB and Kindle. Book excerpt: These Proceedings, consisting of Parts A and B, contain the edited versions of most of the papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at University of San Diego, San Diego, CA, on July 27 to August 1, 1997. The Review was organized by the Center for NDE at Iowa State University, in cooperation with the Ames Laboratory of the USDOE, the American Society of Nondestructive Testing, the National Institute of Standards and Technology, the Federal Aviation Administration, and the National Science Foundation IndustrylUniversity Cooperative Research Centers. This year's Review of Progress in QNDE was attended by approximately 370 participants from the US and many foreign countries who presented a total of approximately 350 papers. As usual, the meeting was divided into 36 sessions with four sessions running concurrently. The Review covered all phases of NDE research and development from fundamental investigations to engineering applications and inspection systems, and methods of inspection science from acoustics to x-rays. The Review continues to experience some fluctuations in size, mostly under pressure from a decrease in funding for NDE research at the US Federal level, but increased participation from foreign laboratories has more than made up the difference. The Review is ideally sized to permit a full-scale overview of the latest developments in a collegial atmosphere that most participants favor. The opening plenary session this year concentrated on advances in imaging technologies and methodologies that have been made in recent years. Dr. K.
