دانلود کتاب Duplex Stainless Steels

Duplex Stainless Steels (DSSs) are chromium-nickel-molybdenum-iron alloys that are usually in proportions optimized for equalizing the volume fractions of austenite and ferrite. Due to their ferritic-austenitic microstructure, they possess a higher mechanical strength and a better corrosion resistance than standard austenitic steels. This type of steel is now increasing its application and market field due to its very good properties and relatively low cost. This book is a review of the most recent progress achieved in the last 10 years on microstructure, corrosion resistance and mechanical strength properties, as well as applications, due to the development of new grades. Special attention will be given to fatigue and fracture behavior and to proposed models to account for mechanical behavior. Each subject will be developed in chapters written by experts recognized around the international industrial and scientific communities. The use of duplex stainless steels has grown rapidly in the last 10 years, particularly in the oil and gas industry, chemical tankers, pulp and paper as well as the chemical industry. In all these examples, topics like welding, corrosion resistance and mechanical strength properties (mainly in the fatigue domain) are crucial. Therefore, the update of welding and corrosion properties and the introduction of topics like texture effects, fatigue and fracture strength properties, and mechanical behavior modeling give this book specific focus and character.Content: Chapter 1 Process: Hot Workability (pages 1–46): Isabel Gutierrez and Amaia Iza?MendiaChapter 2 Corrosion Resistance Properties (pages 47–114): Jacques CharlesChapter 3 Phase Transformation and Microstructure (pages 115–139): Angelo Fernando Padilha and Ronald Lesley PlautChapter 4 Welding Processes, Microstructural Evolution and Final Properties of Duplex and Superduplex Stainless Steels (pages 141–159): Franco Bonollo, Alberto Tiziani and Paolo FerroChapter 5 Thermal Embrittlement of Cast Duplex Stainless Steels: Observations and Modeling (pages 161–208): Andre Pineau and Jacques BessonChapter 6 Low?Cycle Fatigue at Room Temperature (pages 209–240): Iris Alvarez?ArmasChapter 7 Multiaxial Low?Cycle Fatigue Behavior at Room Temperature (pages 241–274): Suzanne Degallaix?MoreuilChapter 8 Partition of Cyclic Plasticity in the 25Cr?7Ni?0.25N Duplex Stainless Steel Investigated by Atomic Force Microscopy (pages 275–302): Jean?Bernard Vogt, Daniel Salazar and Ingrid Proriol SerreChapter 9 Macro? and Micromodeling of the Monotonic and Cyclic Mechanical Behavior of a Forged DSS (pages 303–338): Veronique Aubin and Pierre EvrardChapter 10 Low?Cycle Fatigue at Intermediate Temperatures (pages 339–366): Alberto F.
