Download or read book Ultrasonic Extrusion Reduction in Vehicle and Plasticizer Requirements for Non Clay Ceramics written by and published by . This book was released on 1961 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earlier work on the ultrasonic extrusion of lead and aluminum has been extended to the cold extrusion of plasticized ceramic compositions, resulting in significant improvements in increased extrusion rate (more than 100-fold), decreased extrusion pressure (2 to 10 fold), and in extruded specimen properties. It has also been found possible to extrude materials which are normally nonextrudable because of their low plasticizer or water content. Fused, ground alumina could be ultrasonically extruded with 15% less water than the minimum content without ultrasonics, and only 40 to 60% of that used in normal commercial practice. Significant improvement in the strength of as-extruded shapes, as well as reduced shrinkage and deformation in drying and firing, resulted. Compositions normally using 3 w/o ammonium alginate as a plasticizer can be extruded with 0.2 w/o plastizer when ultrasonically activated. It has been postulated that the ultrasonic effects observed are derived from reduction of surface friction, shear thinning of the thixotropic systems, particle orientation, surface-film rupture, and wetting phenomena. As-extruded specimen improvement was evidenced by a smoother surface and freedom from cracks, tearing, and peeling. When steel dies were used, abrasion of the die surface sometimes caused a superficially discolored surface in nonultrasonic extrusions. The comparable ultrasonic extrusions showed little or no discoloration as the ultrasonic power level was increased. Ultrasonically extruded specimens which were fired in the same kiln loading as their corresponding controls show small but consistent increases in fired density. Water absorption was approximately 75% of the control. The highest moduli of rupture in the fired specimens were found in the ultrasonic specimens even though these required only 25% of the extrusion pressure of the controls.
Download or read book Ultrasonic and Advanced Methods for Nondestructive Testing and Material Characterization written by Chi-hau Chen and published by World Scientific. This book was released on 2007 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic methods have been very popular in nondestructive testing and characterization of materials. This book deals with both industrial ultrasound and medical ultrasound. The advantages of ultrasound include flexibility, low cost, in-line operation, and providing data in both signal and image formats for further analysis. The book devotes 11 chapters to ultrasonic methods. However, ultrasonic methods can be much less effective with some applications. So the book also has 14 chapters catering to other or advanced methods for nondestructive testing or material characterization. Topics like structural health monitoring, Terahertz methods, X-ray and thermography methods are presented. Besides different sensors for nondestructive testing, the book places much emphasis on signal/image processing and pattern recognition of the signals acquired.

Download or read book Nanocomposites written by Subbarayan Sivasankaran and published by BoD – Books on Demand. This book was released on 2019-01-23 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: To have unimaginably outstanding useful properties (physical, mechanical, electrical, optical, chemical, and magnetic) in a single material design is a highly challenging task in the material science community, which can be achieved through nanocomposites. These nanocomposites can be produced from all conventional materials, which include polymers, metals/alloys, and ceramics, by modifying their internal structures. Due to modification of the structures of all kinds of conventional materials, at either the nano or ultra-fine level, the materials exhibit superior performance, which is a boon for all fields of science. In general, nanocomposite materials can be manufactured by solid-state processing techniques, liquid metallurgy, ex-situ and in-situ powder metallurgy, and other basic science synthesis routes. Furthermore, the possibility of making environmentally friendly materials is also possible with nanotechnology. Therefore, to investigate and demonstrate developments in the field of nanocomposites, this book is targeted at all the scientific personnel working in this field.

Available in PDF, EPUB and Kindle. Book excerpt: This multi-contributed book is edited by an expert in the field and includes chapters from across the globe. It is fully cross-disciplinary relating green principles to the food industry, covering legal and policy issues, engineering, food processing and food science. It addresses the alternatives to conventional food processing that have reduced energy requirements or solvent use and how they affect final food quality. Initially, the principles of green chemistry and technologies are outlined to provide a justification and basis for the processing methods that are addressed. This is followed by a discussion of legal and policy issues in both the EU and the US which provide further justification for the need for such technologies and the constraints and benefits of current policies and regulations. The major green technologies available to the food industry are discussed, outlining the main principles and applications of each. The degree to which they are already in commercial use and developments needed to extend their use further are also covered.
