The Roll-diffusion Bonding of Structural Shapes and Panels


Book Description

The report summarizes the progress in recent and current research and development programs to advance the state of the art of the roll-diffusion-bonding process as applied to the manufacture of structural panels and shapes. At the present time, there are seven such NASA and DOD programs in progress. These are reviewed in the report. (Author).







Joining of Titanium


Book Description

This report supplies information on joining processes applicable to titanium and its alloys in sheet metal applications, primarily related directly to airframe construction. Although the material presented here does not cover all titanium joining processes, and omits such processes as plasma-arc, submerged-arc, electroslag, flash, and high-frequency resistance welding, the data presented cover materials up to 2-inches thick in some cases and the report should be useful to anyone seeking titanium joining information. The joining processes covered fall into five categories: welding, brazing, metallurgical bonding (diffusion and deformation bonding), adhesive bonding, and mechanical fastening. The fusion welding processes that are discussed in detail include gas tungsten arc, gas metal arc, arc spot, and electron beam. The resistance processes give extended coverage are spot, roll spot, and seam welding. (Author).










Titanium - 1966


Book Description

This memorandum reproduces thirteen lectures delivered at a Titanium Symposium held on March 28-29, 1966, at Hawthorne, California, under the auspices of the Norair Division of the Northrop Corporation. These lectures follow a logical sequence of topics including production aspects, metallurgy, manufacturing technology, and the design of titanium parts for aircraft and aerospace applications.

Energy and the Environment Cost-Benefit Analysis


Book Description

Energy and the Environment Cost- Benefit Analysis originates from a conference, the objective of which is to set a global standard to measure the cost and benefit of human's production of energy. The book focuses on the analysis of the societal and ecological effects of such a production. It also enumerates some existing sources of energy. The book begins with a discussion on the survey of world energy resources. This topic is followed by a discussion on the utilization of fossil- fuel. A separate chapter focuses on the advantages and disadvantages of fusion power. The next section tackles the formation of solar energy systems for the production of electricity. Another section of the book is devoted to the effects of technological change and economic factors on supply and use of energy sources and production. The text can serve as a valuable tool for executives and engineers from the power industry, educators, scientists, environmentalists, students, and researchers in the field of energy creation and conservation.

Composite Materials


Book Description

The fourth edition of Krishan Chawla's widely used textbook, Composite Materials, offers integrated and completely up-to-date coverage of composite materials. The book focuses on the triad of processing, structure, and properties, while providing a well-balanced treatment of the materials science and mechanics of composites. In this edition of Composite Materials, revised and updated throughout, increasing use of composites in industry (especially aerospace and energy) and new developments in the field are highlighted. New material on the advances in non-conventional composites (which covers polymer, metal and ceramic matrix nanocomposites), self-healing composites, self-reinforced composites, biocomposites and laminates made of metals and polymer matrix composites is included. Examples of practical applications in various fields are provided throughout the book, with extensive references to the literature. The book is intended for use in graduate and upper-division undergraduate courses and as a reference for the practicing engineers and researchers in industry and academia.
