This book was released on 2018-11-19 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapidly solidified alloys, based upon the Al-Fe-V-Si system and designed for elevated temperature applications, were evaluated for superplasticity and diffusion bonding behavior. Alloys with 8, 16, 27, and 36 volume percent silicide dispersoids were produced; dispersoid condition was varied by rolling at 300, 400, and 500 C (572, 752, and 932 F). Superplastic behavior was evaluated at strain rates from 1 x 10(exp -6)/s to 8.5/s at elevated temperatures. The results indicate that there was a significant increase in elongation at higher strain rates and at temperatures above 600 C (1112 F). However, the exposure of the alloys to temperatures greater than 600 C (1112 F) resulted in the coarsening of the strengthening dispersoid and the degradation of mechanical properties. Diffusion bonding was possible using low gas pressure at temperatures greater than 600 C (1112 F) which also resulted in degraded properties. The bonding of Al-Fe-V-Si alloys to 7475 aluminum alloy was performed at 516 C (960 F) without significant degradation in microstructure. Bond strengths equal to 90 percent that of the base metal shear strength were achieved. The mechanical properties and microstructural characteristics of the alloys were investigated. Ting, E.

Download or read book New Trends in Alloy Development Characterization and Application written by Zaki Ahmad and published by BoD – Books on Demand. This book was released on 2015-09-24 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book explores the new developments that have taken place in recent years in the processing and application of aluminium alloys. The chapter on self diffusion shows a complete detail of the mechanism of diffusion in aluminium alloys and how it affects the strength. The chapter on native oxide films gives useful information on the films developed on commercial magnesium alloys. On the analytical side, the details of Mossbauer spectroscopy related to aluminium alloys fully described. One recent development in aluminium alloys is the controlling of pitting corrosion by the application of superhydrophobic coatings. Complete details of the theory and application of hydrophobicity related to aluminium alloys is shown in the two chapters related to hydrophobicity. It is hoped that this book will be found useful by researchers and general readers in the areas described in the book.

This book was released on 2000 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced manufacturing processes such as near-net-shape forming can reduce production costs and increase the reliability of launch vehicle and airframe structural components through the reduction of material scrap and part count and the minimization of joints. The current research is an investigation of the processing-microstruture-property relationships for shear formed cylinders of the Al-Cu-Li-Mg-Ag alloy 2195 for space applications and the Al-Cu-Mg-Ag alloy C415 for airframe applications. Cylinders which had undergone various amounts of shear-forming strain were studied to correlate the grain structure, texture, and mechanical properties developed during and after shear forming.

Available in PDF, EPUB and Kindle. Book excerpt: The major issue of energy saving and conservation of the environment in the world is being emphasized to us to concentrate on lightweight materials in which aluminium alloys are contributing more in applications in the twenty-first century. Aluminium and its related materials possess lighter weight, considerable strength, more corrosion resistance and ductility. Especially from the past one decade, the use of aluminium alloys is increasing in construction field, transportation industries, packaging purposes, automotive, defence, aircraft and electrical sectors. Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are recyclability and its abundant availability in the world. In general, aluminium and its related materials are being processed via casting, drawing, forging, rolling, extrusion, welding, powder metallurgy process, etc. To improve the physical and mechanical properties, scientists are doing more research and adding some second-phase particles in to it called composites in addition to heat treatment. Therefore, to explore more in this field, the present book has been aimed and focused to bridge all scientists who are working in this field. The main objective of the present book is to focus on aluminium, its alloys and its composites, which include, but are not limited to, the various processing routes and characterization techniques in both macro- and nano-levels.

This book was released on 1979 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced aluminum alloys are being developed that will provide major payoffs in terms of weight savings for new aerospace structures. The two property goals are: (1) a 30-percent increase in modulus of elasticity-to-density ratio, and (2) a 20-percent increase in modulus of elasticity-to-density ratio plus a 20-percent increase in strength-to-density ratio, when compared to Al 7075-T76 and without a significant loss in other properties important for structural applications. The program is organized into three phases: 1-a fundamental alloy and process development study; 2-scale-up of two best alloys and evaluation of mill product forms; 3-design evaluation involving selected redesign of aerospace components, analysis of payoffs, and recommendations for manufacturing technology development. Phase 1 activity, to be completed in the first two years, is organized into four Tasks: 1 - development of advanced aluminum alloys containing lithium; 2 - development of advanced aluminum alloys that do not contain lithium; 3 - quantitative microstructural analyses and mechanical property correlations; 4 - study of aerospace structural applications for advanced aluminum alloys including development and application of a method for predicting weight savings. Phase 1 activity is described below; Phases 2 and 3 have not been initiated.
