This book was released on 2018-10-18 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tungsten fiber reinforced copper matrix (W/Cu) composites have served as an ideal model system with which to analyze the properties of metal matrix composites. A series of research programs were conducted to investigate the stress-strain behavior of W/Cu composites; the effect of fiber content on the strength, modulus, and conductivity of W/Cu composites; and the effect of alloying elements on the behavior of tungsten wire and of W/Cu composites. Later programs investigated the stress-rupture, creep, and impact behavior of these composites at elevated temperatures. Analysis of the results of these programs as allows prediction of the effects of fiber properties, matrix properties, and fiber content on the properties of W/Cu composites. These analyses form the basis for the rule-of-mixtures prediction of composite properties which was universally adopted as the criteria for measuring composite efficiency. In addition, the analyses allows extrapolation of potential properties of other metal matrix composites and are used to select candidate fibers and matrices for development of tungsten fiber reinforced superalloy composite materials for high temperature aircraft and rocket engine turbine applications. The W/Cu composite efforts are summarized, some of the results obtained are described, and an update is provided on more recent work using W/Cu composites as high strength, high thermal conductivity composite materials for high heat flux, elevated temperature applications.

This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of selected alloying elements on the elevated temperature tensile properties of tungsten fiber reinforced composites were studied. Composites were made of copper, copper- 2 percent chromium and copper- 10 percent nickel reinforced with various volume percents of uniaxially oriented tungsten fibers. The composites were tested in tension at temperatures up to 1800 degrees F.A comparison of the elevated-temperature tensile properties of tungsten fiber - copper alloy composites, representing soluble systems, was made with tungsten fiber - copper composites, representing a mutually insoluble system. The effects of alloying on the elevated-temperature tensile properties of tungsten fiber reinforced composites was also studied. A linear relation existed at elevated temperatures between tensile strength and volume percent fiber content for all the systems investigated. The copper alloy composites were weaker in tension at high volume percent fiber contents than copper composites in which alloying with the fiber did not occur. The tensile strength of the alloyed tungsten fiber decreased with increasing penetration of the alloying element into the tungsten fiber.

Book Synopsis Liquid-Phase Sintering (LPS) of Tungsten-Based Heavy Alloys: Hafnium and Copper Addition by :
Download or read book Liquid-Phase Sintering (LPS) of Tungsten-Based Heavy Alloys: Hafnium and Copper Addition written by and published by . This book was released on 1996 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tungsten heavy alloys of composition 80W-20(Hf-Cu) weight-percent have been fabricated by liquid phase sintering (LPS). Two hafnium-rich, near eutectic compositions of the Hf-Cu system were utilized to lower the sintering temperature in the W-Hf system. Intermetallic compounds can be harmful to the mechanical properties of tungsten-based heavy alloys and avoiding them was deemed to be critical in the development of these new alloys. Therefore, an understanding of the processing conditions by which these compounds are formed was a vital component of this work. The threshold temperature for the formation of the intermetallic HfW2 was determined by powder x-ray diffraction (XRD) to be approx. 1,400 deg C. This threshold temperature was well above the predicted LPS temperature of 1,310 deg C for hafnium-rich compositions in the Hf-Cu binary. To study the effects of cooling rates on the formation and stability of another possible intermetallic phase CuHf2, uniaxially pressed 90Hf-10Cu elemental powder blends were heated to 1,310 deg C for 30 min and subjected to four different cooling rates. The CuHf2 phase was, however, observed at room temperature for all cooling rates examined. Two ternary W-Hf-Cu compositions were selected by fixing the tungsten content at 80 weight-percent and utilizing two near eutectic Hf-Cu compositions. Copper additions in the W-Hf alloy system, however, resulted in the formation of the HfW2 intermetallic phase at temperatures as low as 995 deg C. The microstructure was comprised of interpenetrating, semicontinuous networks of nearly pure W with HfW2.

Book Synopsis Liquid Phase Sintering by : R.M. German
Download or read book Liquid Phase Sintering written by R.M. German and published by Springer Science & Business Media. This book was released on 1985-12-31 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years there has been rapid growth in the activities involving particulate materials because of recognized advantages in manufacturing. This growth is attributed to several factors; i) an increased concern over energy utilization, ii) a desire to better control microstructure in engineermg materials, iii) the need for 1mproved material economy, iv) societal and economic pressures for higher productivity and quality, v) requirements for unique property combinations for high performance applica tions, and vi) a desire for net shape forming. Accordingly, liquid phase sintering has received increased attention as part of the growth in particulate materials processing. As a consequence, the commercial applications for liquid phase sintering are expanding rapidly. This active and expanding interest is not well served by available texts. For this reason I felt it was appropriate to write this book on liquid phase sintering. The technology of liquid phase sintering IS quite old and has been in use in the ceramics industry for many centuries. However, the general perception among materials and manufacturing engineers is that liquid phase sintering is still a novel technique. I believe the diverse technological appli cations outlined in this book will dispel I such impressions. Liquid phase. sintering has great value in fabricating several unique materials to near net shapes and will continue to expand in applications as the fundamental attrib utes are better appreciated. I am personally involved with several uses for liquid phase sintering.

Book Synopsis Critical Aspect Ratio for Tungsten Fibers in Copper-nickel Matrix Composites by : Robert W. Jech
Download or read book Critical Aspect Ratio for Tungsten Fibers in Copper-nickel Matrix Composites written by Robert W. Jech and published by . This book was released on 1975 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress-rupture and tensile tests were conducted at 816 deg C (1500 deg F) to determine the effect of matrix composition on the minimum fiber length to diameter ratio (critical aspect ratio) below which fibers in a tungsten fiber/copper-nickel alloy matrix composite could not be stressed to their ultimate load carrying capability. This study was Intended to simulate some of the conditions that might be encountered with materials combinations used in high-temperature composites. The critical aspect ratio for stress-rupture was found to be greater than for short-time tension, and it increased as the time to rupture increased. The Increase was relatively slight, and calculated fiber lengths for long service appear to be well within practical size limits for effective reinforcement and ease of fabrication of potential gas turbine components.
