Book Description
An iron-based, corrosion-resistant, precipitation strengthened, martensitic steel essentially free of delta ferrite for use at high temperatures has a nominal composition of 0.05-0.1 C, 8-12 Cr, 1-5 Co, 0.5-2.0 Ni, 0.41-1.0 Mo, 0.1-0.5 Ti, and the balance iron. This steel is different from other corrosion-resistant martensitic steels because its microstructure consists of a uniform dispersion of fine particles, which are very closely spaced, and which do not coarsen at high temperatures. Thus at high temperatures this steel combines the excellent creep strength of dispersion-strengthened steels, with the ease of fabricability afforded by precipitation hardenable steels.

Book Description
Creep-resistant steels are widely used in the petroleum, chemical and power generation industries. Creep-resistant steels must be reliable over very long periods of time at high temperatures and in severe environments. Understanding and improving long-term creep strength is essential for safe operation of plant and equipment. This book provides an authoritative summary of key research in this important area.The first part of the book describes the specifications and manufacture of creep-resistant steels. Part two covers the behaviour of creep-resistant steels and methods for strengthening them. The final group of chapters analyses applications in such areas as turbines and nuclear reactors.With its distinguished editors and international team of contributors, Creep-resistant steels is a valuable reference for the power generation, petrochemical and other industries which use high strength steels at elevated temperatures. Describes the specifications and manufacture of creep-resistant steels Strengthening methods are discussed in detail Different applications are analysed including turbines and nuclear reactors

Book Description
The properties of precipitation-hardened austenitic stainless steels are adversely affected by the precipitation of unwanted brittle phases, like sigma (nonmagnetic intermetallic phase that is composed of iron and chromium) and Laves (Fe2Nb) These stainless steels are also susceptible to stress corrosion cracking. The induced residual stress in the material in turn reduces its creep strength. The strain beyond a certain limit affects its creep-resistant property appreciably, and hence, beyond a certain strain, these stainless steels are to be solution-treated for stress relief. Characterization studies on precipitation-strengthened creep-resistant austenitic stainless steel are presented in this article. Effects of strain and aging on microstructures are also evaluated. In order to understand the precipitation-strengthening behavior and effect of strain on Super304H (CC2328-2), the material was strained and aged at 650C for a period ranging from 7h to 4weeks, and then the microstructures were studied using an optical microscope. Experiments were carried out on tubes with no strain and tubes with strain, which were aged at 650C. The results show that beyond a threshold strain of ~17 %, the material becomes deteriorated, and to regain its original microstructure, solid solution treatment is necessitated.

Book Description
The cold spray process produces dense, low oxide coatings which can be used in such diverse applications as corrosion control and metals repair. It has emerged as an important alternative to thermal spray coating techniques in certain areas. This pioneering book reviews both the fundamentals of the process and how it can best be applied in practice. The first part of the book discusses the development of the process together with its advantages and disadvantages in comparison with thermal spray coating techniques. Part two reviews key process parameters such as powders, nozzle design, particle temperature and velocity, and particle/substrate interaction. It also describes portable and stationary cold spray systems. The final part of the book discusses how the cold spray process can be applied in such areas as improved wear, corrosion protection, electromagnetic interference shielding and repair of damaged components. The cold spray materials deposition process is a standard reference on this important process and its industrial applications. Examines the fundamentals of the cold spraying process Assesses how the technique can best be applied in practice Describes portable and stationary cold spray systems

Book Description
High-performance alloys that can withstand operation in hazardous nuclear environments are critical to presentday in-service reactor support and maintenance and are foundational for reactor concepts of the future. With commercial nuclear energy vendors and operators facing the retirement of staff during the coming decades, much of the scholarly knowledge of nuclear materials pursuant to appropriate, impactful, and safe usage is at risk. Led by the multi-award winning editorial team of G. Robert Odette (UCSB) and Steven J. Zinkle (UTK/ORNL) and with contributions from leaders of each alloy discipline, Structural Alloys for Nuclear Energy Applications aids the next generation of researchers and industry staff developing and maintaining steels, nickel-base alloys, zirconium alloys, and other structural alloys in nuclear energy applications. This authoritative reference is a critical acquisition for institutions and individuals seeking state-of-the-art knowledge aided by the editors’ unique personal insight from decades of frontline research, engineering and management. Focuses on in-service irradiation, thermal, mechanical, and chemical performance capabilities. Covers the use of steels and other structural alloys in current fission technology, leading edge Generation-IV fission reactors, and future fusion power reactors. Provides a critical and comprehensive review of the state-of-the-art experimental knowledge base of reactor materials, for applications ranging from engineering safety and lifetime assessments to supporting the development of advanced computational models.

Book Description
This book discusses GaN and Related Alloys and reflects an emerging emphasis on the binaries of InN and AlN. The major thrust here is the topical development of thin-film growth, bulk growth techniques, methods to cover the full ternary and quaternary alloy ranges toward InN and AlN and their characterization; strategies for structural defect reduction and their characterization; ways to better control p-type doping and its characterization; device and defect physics, including polarization effects; physics of surfaces and interfaces; and device processing techniques. In addition, advances in MBE devices, high-power electronics, RF performance of electronics, UV emitters, high-efficiency light emitters, photo and chemical sensors, as well as new applications within the group-III nitrides, are also covered. The book captures the current status of this field and will be useful for researchers working with group-III nitrides, as well as for students who seek entry into this subject.
