Available in PDF, EPUB and Kindle. Book excerpt: Among the obstacles encountered in the development of intermetallic matrix composites are (1) the thermodynamic and mechanical incompatibility between the matrix and reinforcement phases and (2) the matrix reinforcement interfacial properties which are not ideal from the standpoint of achieving optimum properties in the composite as a whole. In the past, the first of these problems has been addressed by coating the reinforcements with some sort of barrier or compliant layer before their introduction into the matrix. The various coating methods investigated (sol-gel, CVD, PVD) tend to be expensive, time consuming and unreliable with respect to producing sound coatings. This research program was initially concentrated on identifying more cost effective and reliable schemes for developing the requisite coatings. The basic approach is to identify simple processing schemes whereby a beneficial reaction product (or products) is produced in-situ at the interfaces between the matrix and reinforcement during consolidation or subsequent heat treatment. As the research evolved, greater focus was placed on the need to achieve a better understanding of microstructural evolution during in-situ displacement reactions and on the correlation between the evolved microstructures and the mechanical properties. In the case of silicide based IMC's, there was a clear need to determine the influence of discrete silica particles, incorporated during the consolidation of powder samples, on the mechanical properties and on both grain size and shape.
Download or read book Structure and Properties of Intermetallic Composites Synthesized in Situ Using Solid State Displacement Reactions written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid state displacement reactions can produce in situ intermetallic matrix composites in a process where an intermetallic phase(s) and a potential reinforcing phase(s) are grown together during a solid state reaction. Interwoven and dispersed microstructures, important for desirable composite properties, have been produced by means of displacement reaction processing techniques. Two such composites have been synthesized: MoSi[sub 2] reinforced with SiC particles, and NiAl/Ni[sub 3]Al reinforced with Al[sub 2]O[sub 3]. Strength in bending and chevron-notch fracture toughness have been determined as a function of temperature and measured properties compare favorably with composites produced by other means. The measured properties are discussed with regard to the observed microstructures. The potential for displacement reaction processing is assessed and appears to be a cost-effective synthesis method compared to others.

Download or read book Investigation of Fiber Reinforced Metal Matrix Composites Using a High Energy Rate Forming Method written by Edward A. Snajdr and published by . This book was released on 1968 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to investigate fiber-reinforced metal matrix composites by a High Energy-Rate Forming method (HERF). Phase 1 consisted of constituent characterization, preparation of compatibility specimens and tensile screening tests on seven composite systems: SiC Whisker/Ti-6Al-4V; SiC Whisker/Ti; Al2O3 Whisker/Ti-6Al-4V; Al2O3 Whisker/Ti; Al2O3 Whisker/Ni; Al2O3 Whisker/Fe-Cr-Al; and SiC Filament/Ti-6Al-4V. Phase 2 consisted of process development and optimization, followed by characterization of one of two systems selected during Phase 1 (SiC filament in Ti-6Al-4V). The filament system provided improved high temperature stress-rupture properties. Rule-of-mixtures tensile strengths were obtained with 28 vol % specimens. The Ni-Al2O3 whisker system could not be fabricated with powder metallurgy techniques due to fiber breakage.
Download or read book Mechanical Behavior of Fiber Reinforced SiC RBSN Ceramic Matrix Composites Theory and Experiment written by and published by . This book was released on 1991 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical behavior of continuous fiber reinforced SiC/RBSN composites with various fiber contents is evaluated. Both catastrophic and noncatastrophic failure is observed in specimens tested for tensile strength. Damage and failure mechanisms are identified via in-situ monitoring using nondestructive evaluation techniques throughout the loading history. Effects of fiber/matrix interfaces debonding (splitting) parallel to the fibers are discussed. Statistical failure behavior of fibers is also observed, especially when interfaces are weak. Microstructure models that incorporate residual stresses to calculate the critical matrix cracking strength, ultimate strength and work of pull-out are reviewed and used to predict composite response. For selected test problems, experimental measurements are compared to analytical predictions.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanical properties of Nicalon-fiber-reinforced silicon carbide matrix composites with two different fiber lay-up sequences (0°/40°/60° and 0°/45°) were evaluated at various temperatures ranging from ambient to 1300°C. Composites with 0°/40°/60° fiber lay-up sequence showed a higher average first matrix cracking stress than that of 0°/45° composites. The measured room-temperature ultimate strength of the 0°/40°/60° composites was 300 MPa compared to 180 MPa for the 0°/45° composites. These measured ultimate strengths were correlated to the predictions made with an analytical model and to in-situ fiber strength characteristics. The large difference in room-temperature ultimate strengths between the two sets of composites is attributed to the relative contributions of the off-axis fibers to the load-bearing capacity of each composite. Up to 1200°C, ultimate strength and work-of-fracture in each set of composites increased, but then declined above 1300°C. The decreases were correlated to in-situ Nicalon fiber strength and fiber/matrix interface degradation.

Download or read book The Effect of Processing on the Interface Microstructure and Properties of Coated Fiber Reinforced Glass Ceramic Matrix Composites written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this program was to study the processing of coated fiber reinforced glass-ceramic matrix composites that will result in reproducible, reliable fiber coatings and the composites that incorporate them, for use to 1200C in advanced gas turbine engine applications. The primary glass-ceramic system was a barium magnesium aluminosilicate (BMAS), while the fibers were Ceramic Grade Nicalon Si-C-O and Nextel 720 aluminosilicate fibers, as well as new advanced high temperature SiC based fibers. The primary fiber coating system was layered BN(+C) for the Nicalon fiber composites, and BN, monazite (LaPO4), and fugitive carbon for the Nextel 720 fiber composites. The layered 3M BN(+C) coatings on Nicalon fibers produced very strong and "tough" BMAS glass-ceramic matrix composites, due to the limited matrix element diffusion through the coating and matrix crack deviation within the layered coating structure. These composites exhibited excellent tensile fatigue and stress-rupture properties, although oxidation of the layered BN coatings at intermediate temperatures (700-900C) under conditions of high fatigue stress (138 MPa) may potentially limit the stress at which these composites can be utilized for structural applications. Alternate BN and Si-doped BN coatings from other vendors did not perform as well, with excessive BN crystallization occurring during composite fabrication. Nextel 720 aluminosilicate fibers with either BN, fugitive carbon, or C/Al2O3/C coatings did not result in strong or "tough' BMAS matrix composites for a variety of reasons, but primarily because of coating debonding leading to fiber/matrix interactions. Monazite (LaPO4) coated Nextel 720 fibers reacted excessively with the BMAS matrix during composite fabrication. The crystalline SiC fibers from the U. of Fla., especially with the in-situ BN coatings, appear to offer future promise for high temperature CMC reinforcement.
