Covering the subject of steel metallurgy from its applications point of view, this book discusses the applied metallurgical knowledge required for easy-learning about steels, their properties, specifications, heat treatment and applications. :
The book is conceptually divided into four parts:
ÿThe first part introduces the basic metallurgical facts about steel and its characteristics, covers the most important aspects of steel metallurgy, its applications, and fundamental features of steelmaking and rolling processes, and highlights the different types of properties of steel and the need for testing and evaluation:
ÿDiscussing the classifications, specifications and properties of steels in a more quantitative manner (based on popular standards and standard-based data), the second part focuses on different steel grades and their merits and properties for selection and applications
ÿThe third part focuses on heat treatment and welding of steels, various heat treatment methods and their purposes, and basic aspects of welding and welding precautions in steels
ÿDwelling on the application of steels, the fourth part discusses the totality of steel applications from the point of view of reliability and component integrity, the importance of cost and quality optimization in applications, and the criticality of design and manufacturing quality for prevention of failures
Steel Metallurgy has been designed to provide all necessary information and practice-based knowledge about steel characteristics, steel properties, steel grades, and steel applications for selecting, processing and using steels with right understanding and for the right purposes.ÿ
Highlights of the book:
ÿProvides deep theoretical and practice-based knowledge about steels, their properties, specifications, heat treatment and applications
ÿIncludes large number of examples, illustrations and case studies
ÿIncludes elaborate Index of contents for cross-referencing, a Bibliography for further reading and reference, and Glossary of Important Metallurgical Terms
ÿSimplified and highly illustrated narration ideal for metallurgical students, metallurgists and non-metallurgical engineers
The book is intended for both students and practitioners. The book will help students of metallurgy and other engineering disciplines to understand the applied and functional-basics of steels relating to their properties, specifications and applications. Engineers and technical personnel in industries dealing with steel processing and its uses will benefit from the hard look the book takes for the precise selection of steel for the right purposes by providing workable knowledge on steel metallurgy and steel specifications.
The volume contains 18 chapters by expert authors with diverse cultural backgrounds and provides a wide ranging canvas for multifaceted understanding of the terror phenomenon. The opening section, 'Understanding Terrorism: Psychosocial Issues', places emphasis on developing a well-heeled construct with strong theoretical foundations and empirical understanding of the psycho-socio-cultural dynamics involved in perpetration of terror acts. The second section, 'Countering Terrorism: Psychosocial Avenues', flows from the understanding thus attained and expounds counter-terror strategies and preventive measures that go beyond the obvious short-term goals and envisage the creation of a peaceful world.
Recent developments in the field of fire- and heat-resistant materials have led to significant improvements in thermal protective clothing. In parallel with this, the complexity and risk levels of fires, especially in industrial-storage facilities, and developments in health and safety cultures have increased the demand for high-performance heat- and flame-resistant clothing and equipment, designed to mitigate skin burn injuries and reduce risk of death from fire hazards.
Throughout the work, the gaps and limitations in existing test methods and standards are identified, and approaches are recommended for the development of enhanced test methods. Scenario modeling and its implications for firefighters’ protective clothing is discussed, and various factors affecting performance are established. Finally, various key issues related to thermal protective clothing are addressed to guide the future research in the field of thermal protective clothing for firefighters. This book will help materials-textile engineers to develop high performance thermal protective clothing that can enhance the protection, safety, and comfort of firefighters.Offers a helpful guide to the successful specification and design of high performance protective clothing to meet the high standards of today's regulatory frameworkIntroduces the new materials technical innovations that are transforming fire protective clothingExplores the role of clothing from the operational perspective, including technical innovationsOffers a critical review of the test methods and existing standards to evaluate the thermal protective and physiological comfort performances of the fabrics and clothing
The book covers structural arrangement with longitudinal and transverse framing systems based on the service load, and explains basic structural elements like hatch side girders, hatch end beams, stringers, etc. along with structural subassemblies like floors, bulkheads, inner bottom, decks and shells. It presents in detail double bottom construction, wing tanks & duct keels, fore & aft end structures, etc., together with necessary illustrations. The midship sections of various ship types are introduced, together with structural continuity and alignment in ship structures.
With regard to construction materials, the book discusses steel, aluminum alloys and fiber reinforced composites. Various methods of steel material preparation are discussed, and plate cutting and forming of plates and sections are explained. The concept of line heating for plate bending is introduced.Welding power source characteristics, metal transfer mechanisms, welding parameters and their effects on the fusion zone, weld deposit, and weld bead profile are discussed in detail. Various fusion welding methods, MMAW, GMAW, SAW, Electroslag welding and Electrogas welding and single side welding are explained in detail. Friction stir welding as one of the key methods of solid state welding as applied to aluminum alloys is also addressed.
The mechanisms of residual stress formation and distortion are explained in connection with stiffened panel fabrication, with an emphasis on weld induced buckling of thin panels. Further, the basic principles of distortion prevention, in-process distortion control and mitigation techniques like heat sinking, thermo-mechanical tensioning etc. are dealt with in detail.
In its final section, the book describes in detail various types of weld defects that are likely to occur, together with their causes and remedial measures. The nondestructive testing methods that are most relevant to ship construction are explained. Lastly, a chapter on accuracy control based on statistical principles is included, addressing the need for a suitable mechanism to gauge the ranges of variations so that one can quantitatively target the end product accuracy.
Strap yourself for an emotional roller coaster ride as you experience Anurita’s world through the pages of her diary. Laugh with Anurita, wipe away her tears, revel in her wisdom and be a part of her life’s conversations.
A bold and daring young woman from a little village in India, Anurita chooses to tread the untrodden path, against the dictates of a judgmental society. But she is determined to seek the true meaning of her life at any cost. As she follows her heart all the way to the city and beyond, she is met with turbulences of all kinds. A stunningly handsome middle-aged man stirs in her feelings of love and passion; but her romantic fantasy meets with an abrupt end. And then, in a faraway country, she loses her friends to an unexpected tragedy.
Just when everything seems to be going awry and she is about to give up on humanity, it rains. As rains from the smoky sky fall on the Earth, Anurita discovers fireflies in the darkness, dancing on the rain-bathed petals of lovely carnations, the flowers of god.
