Available in PDF, EPUB and Kindle. Book excerpt: Advanced ceramic-matrix composites (CMCs) outperform traditional ceramics in many ways and have shown potential for demanding applications. Net-shape manufacture of CMC parts is challenging, and many advanced applications demand robust and reliable integration technologies such as brazing. Brazing of CMC/metal joints is reviewed, highlighting scientific issues together with a discussion of some of the challenges that brazing of CMCs presents. Brazing practices for SiC–SiC, C–SiC, C–C, ZrB2-based ultra-high-temperature composites, and oxide, nitride and silicate-based composites are presented. Recent research results on interface microstructure, composition and properties are discussed. Scaling effects, time–temperature–environment dependent thermomechanical properties, design guidelines and life-prediction analyses, and tools for CMC/metal joints to be used in structures constitute future research imperatives.

Available in PDF, EPUB and Kindle. Book excerpt: Metal–nonmetal brazing is an established joining method used to fabricate products such as hermetic electronic packages, insulators for power generation and turbo-machinery components. Brazing presents opportunities for the materials engineer seeking to utilize recently engineered materials in advanced applications and extreme environments. Three commonly used brazing methods used for joining metals to nonmetals will be discussed: conventional brazing methods that use metallization coatings on the nonmetal surface to be brazed; active brazing methods that eliminate the need for metallization coatings; and direct brazing methods utilizing conventional brazing filler metals to join and seal packages without prior metallization.

Download or read book Advances in brazing written by W. Tillmann and published by Elsevier Inc. Chapters. This book was released on 2013-03-04 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important brazing application is the production of cutting and machining tools. This chapter provides an overview of brazing alloys for the joining of cutting materials. Process-related problems and solutions are presented and discussed. High strength values can be achieved with the right filler alloy and joint design. Most cemented carbides consist of a hard material such as tungsten carbide and a metallic binder. Due to the high carbide content, wetting and bonding reactions have to be monitored. Addition of active elements can help to induce a wetting reaction. Brazing ceramic cutting materials requires the use of active filler alloys to achieve a wetting reaction. The chapter reviews the alloys required. A joint can be weakened by interfacial effects or mismatches in physical properties. Employing the right filler metal with an adapted brazing process can significantly improve joint quality. Stress calculations based on the finite element method contribute to better joint design with reduced stress levels.

Available in PDF, EPUB and Kindle. Book excerpt: The phenomena involved in a brazing process constitute a set of very complex spatially distributed, transient physical and chemical processes, influenced by multiple parameters. This has been difficult to model reliably. This chapter offers a high level review of three broad areas of modeling: (i) the heating/cooling process during brazing, (ii) the thermomechanical behavior of brazed assemblies, and (iii) micro-scale phenomena, taking place in the joint zone and primarily related to transport phenomena. This discussion illustrates the importance of modeling brazing processes and its increasing contribution to the long-lasting success of the art.

Available in PDF, EPUB and Kindle. Book excerpt: This chapter investigates the problem of brazing heat-resistant materials – high nickel-base and γ-TiAl-base intermetallic alloys. Diffusion brazing with filler metals of the Ni–Cr–B and Ni–Cr–B–Si systems is inefficient for nickel alloys, while composite filler metals based on these systems yield satisfactory results. When used as an alternative to boron- and silicon-containing filler metals, alloys of the Ni–Cr–Zr systems do not form hard and brittle phases at the interface in the joints. Filler metals based on the Ti–Zr system are best suited for joining γ-TiAl-base intermetallic alloys. Ti–Zr–Fe and Ti–Zr–Mn alloys, which show promise as brazing filler metals are selected, and structures and mechanical properties of the brazed joints are presented.

Book excerpt: Ceramics are inorganic non-metallic materials made from natural or synthetic compounds using shaping and high-temperature sintering processes. At present, the poor plasticity and low impact resistance of engineering ceramics have limited their further application. Joining ceramics or composites to metal is challenging because of their chemical dissimilarity and differences in coefficient of thermal expansion. The complexity and high cost of procedures that can overcome these problems limit their application. In this chapter, the difficulties of brazing ceramics and solutions are presented. The brazing of oxide ceramics, nitride ceramics, carbide ceramics and C/C composites is discussed in more detail.
