DOWNLOAD EBOOKMaraging steels are high-strength steels combined with good toughness. They are used particularly in aerospace and tooling applications. Maraging refers to the ageing of martensite, a hard microstructure commonly found in steels.Maraging steels: modelling of microstructure, properties and applications covers the following topics: Introduction to maraging steels; Microstructure of maraging steels; Mechanical properties of maraging steels; Thermodynamic calculations for quantifying the phase fraction and element partition in maraging systems and precipitation hardening steels; Quantification of phase transformation kinetics in maraging steels; Quantification of age hardening in maraging steels; Maraging steels and overageing; Precipitation hardening stainless steel; Applications of artificial neural network on modelling maraging steel properties.With its distinguished authors, Maraging steels: modelling of microstructure, properties and applications is a standard reference for industry and researchers concerned with maraging steels and modelling as well as users of maraging steels in the aerospace and tooling sectors. The book includes both conventional maraging steels and precipitation hardened (PH) stainless steels. Provides an overview of maraging steels including microstructure and mechanical properties Reviews thermodynamic calculations for quantifying the phase fraction and element partition in maraging steels Includes chapters on the quantification of phase transformation kinetics and age hardening in maraging steels

DOWNLOAD EBOOKThe structural materials used in airframe and propulsion systems influence the cost, performance and safety of aircraft, and an understanding of the wide range of materials used and the issues surrounding them is essential for the student of aerospace engineering.Introduction to aerospace materials reviews the main structural and engine materials used in aircraft, helicopters and spacecraft in terms of their production, properties, performance and applications. The first three chapters of the book introduce the reader to the range of aerospace materials, focusing on recent developments and requirements. Following these introductory chapters, the book moves on to discuss the properties and production of metals for aerospace structures, including chapters covering strengthening of metal alloys, mechanical testing, and casting, processing and machining of aerospace metals. The next ten chapters look in depth at individual metals including aluminium, titanium, magnesium, steel and superalloys, as well as the properties and processing of polymers, composites and wood. Chapters on performance issues such as fracture, fatigue and corrosion precede a chapter focusing on inspection and structural health monitoring of aerospace materials. Disposal/recycling and materials selection are covered in the final two chapters. With its comprehensive coverage of the main issues surrounding structural aerospace materials,Introduction to aerospace materials is essential reading for undergraduate students studying aerospace and aeronautical engineering. It will also be a valuable resource for postgraduate students and practising aerospace engineers.

DOWNLOAD EBOOKSeveral different ways of microstructural control were attempted in maraging type steels in order to achieve a combination of high strength and high toughness. In Section I, the composition, processing and mechanical properties of Fe-Ni-Ti alloys are described. It is found that high nickel content and high aging temperature are beneficial for toughness. This alloy system, however, does not exhibit high toughness due to the extensive grain boundary precipitation during aging. In Section II, the well-known toughening mechanisms, i.e., grain refinement, retained austenite, and the TRIP mechanism are incorporated to a 250 grade maraging stee. The improvement in fracture toughness is obtained only when the retained austenite remains stable during deformation. The microduplex maraging steel preserves its high fracture toughness upon high strain rate fracture in contrast to most of the martensitic steels. In Section III initial success is reported with an alternate toughening technique: the introduction of a dense mobile dislocation density through rapid phase transformation of a partially maraged structure.

DOWNLOAD EBOOKThis report resulted from a survey of users and manufacturers of maraging steels, Government agencies, research institutions, and published literature. It presents the technical status of the 18-percent nickel maraging steels in detail and brings together a large body of knowledge with regard to the metallurgical and engineering aspects of maraging steels. Since such steels were first announced in 1959, they have become highly important in aerospace, defense, and industrial work. The requirements of the National Aeronautics and Space Administration have given impetus to their development, and research now underway is expected to result in further improvements and applicability. The NASA Office of Technology Utilization sponsored this report as part of its program to disseminate information on technological developments which appear to be useful for general industrial applications.
