The book describes the method of remelting consumable electrodes with an electric are burning between the surface of a liquid slag bath and a consumable electrode in a water-cooled copper mould. The method combines the possibilities of treatment of liquid metal with the electric arc in the gas atmosphere and the liquid slag and the advantages of plasma-arc and electro slag remelting. The technological possibilities, design features of melting systems and results of experimental and industrial melting trials of steels and alloys are described. In addition to remelting structural steels, special attention is given to the possibility of alloying the metal with nitrogen from the gas phase, without using expensive nitrogen-bearing nonmetallic compounds, e.g. silicon nitride. It is shown that arc slag remelting can also be used efficiently in producing ingots of titanium and its alloys. The results obtained in this method are compared with electro slag remelting and plasma arc remelting. Data on energy consumption and metal quality are also presented.

Product Description
While residual stress can be a problem in many industries and lead to early failure of component, it can also be introduced deliberately to improve lifetimes. Knowledge of the residual stress state in a component can be critical for quality control of surface engineering processes or vital to performing an accurate assessment of component life under fatigue loading.
Neutron and synchrotron X-ray diffraction have emerged as leading techniques for stress analysis, as they can penetrate many millimetres or centimetres into components, allowing nondestructive measurement of the internal strains. Both methods require the use of costly facility-based equipment, but great advantages are obtained from the ability to probe the stress state deep below a specimen's surface.
Analysis of Residual Stress by Diffraction Using Neutron and Synchrotron Radiation gives an overview of the principles of these techniques and examples of their applications to a range of materials and engineering problems. It contains 20 chapter contributed by leading international experts in residual stress analysis, who explore the theoretical basis of stress analysis by diffraction methods, the practical implementation of the methods, and examples of key applications. The applications discussed include the determination of internal stresses in weldments, in composite materials, following shot peening, and in ceramics.
This book will be useful for engineers and scientists who work in any field where residual stresses are of importance, and for anyone involved with the application of neutron or synchrotron radiation for stress management. As the techniques become a basic component of the measurement toolkit for stress analysis, an appreciation of the practicalities and limitations of these methods in practice will be important throughout a range of engineering and scientific fields.
------------------------
If you have anything to do with residual stresses and their consequences, this book is for you. Lots of examples of residual stress problems, and the leading methods available to measure them. A series of detailed articles on the methods, their application, and a range of problems where the methods have been applied.

Alloying Liquid Metal with Nitrogen from Electric ARC Plasma
Author: V I Lakomskii (Author) | Size: 7 MB | Format:PDF | Quality:Original preprint | Publisher: Cambridge International Science Publishi | Year: 1999 | pages: 223 | ISBN: 1898326533-978-1898326533
In the monograph, the author summarises the results obtained in research and investigations of the gas-liquid metal system at temperatures typical of electric arc welding and electrometallurgy processes. Special attention is given to the problems of sorption of diatomic homonuclear gases, especially nitrogen from electric arc plasma, by metal melts. It is shown that when the metal absorbs the gas from plasma the system does not reach the thermodynamic equilibrium state. Investigations were carried out into processes taking place in the gas-plasma layer bordering with the metal. These processes determine the gas content of liquid steel.

Book Description
Advanced welding processes provides an excellent introductory review of the range of welding technologies available to the structural and mechanical engineer. The book begins by discussing general topics such power sources, filler materials and gases used in advanced welding. A central group of chapters then assesses the main welding techniques: gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), high energy density processes and narrow-gap welding techniques. Two final chapters review process control, automation and robotics. Advanced welding processes is an invaluable guide to selecting the best welding technology for mechanical and structural engineers.

I need soft copy of "Hand book on underreamed and bored compaction pile foundations" by Sharma, D., Jain, M.P. and C. Prakash. 1978, Central Building Research Institute, Roorkee, India.
The popular, easily accessible guide to the design of reinforced concrete structures—now updated and revised
Structural Concrete, Fifth Edition provides complete guidance to the analysis and design of reinforced and prestressed concrete structures. This new edition brings all material up to date while maintaining the book's practical, logical, easy-to-follow approach. Coverage includes the latest ACI 318 - 11 code rules, emphasizing the code's strength approach and strain limits. Additional codes, standards, and specifications, as well as material properties and specific loads and safety provisions are also examined in detail.
Drawing on decades of experience in industry and academia, the authors include numerous SI unit examples and design tables along with step-by-step instructions on how to analyze and design for each type of structural member. They clearly explain all key concepts one should know before tackling design formulas, and supplement the discussion with helpful end-of-chapter summaries, references, and problems. New and updated material in this edition includes:
The application of shear design to beams with variable length in actual structure
The design of deep beams employing ACI and AASHTO strut-and-tie approach
The design of stepped-type reinforced concrete stairs, not covered anywhere else
Seismic design and analysis utilizing the IBC 2012 and ASCE 7-10 code
The design of curved beams subject to flexure, shear, and torsion
Prestressed concrete bridge design according to AASHTO specifications
Examples for predicting shrinkage and creep of concrete in both U.S. and SI units
Structural Concrete, Fifth Edition arms civil and structural engineers with a complete set of tools for designing concrete structures with confidence. It is also an excellent resource for students of civil engineering.

Finite-Element Design of Concrete Structures, 2nd edition
GA Rombach (Author)
Book Description
Publication Date: November 14, 2011 | ISBN-10: 0727741896 | ISBN-13: 978-0727741899 | Edition: 2
Numerical calculations based on the finite element design method have become a standard tool for the design of many structures. In this book, the author highlights that complex numerical calculations should not be used to compensate for any lack of practical knowledge of the behaviour of a structure. This new edition up to date with the increasingly complex finite element models and nonlinear material analysis being used in the field. The book focuses on and references Eurocode 2 throughout.
About the Author
From 1990-1996 Professor Rombach worked as a design and project manager for a major construction company on many projects - particularly bridges - around the world. Since 1996 he has been a professor in the field of design of concrete structures at the University Hamburg-Harburg. In 2000 be became a Certified Checking Engineer in Germany.
