Download or read book Relationship Between Metallurgical Structure and Properties of a Precipitation Hardening Stainless Steel written by R. H. Kaltenhauser and published by . This book was released on 1965 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical properties and corrosion resistance of AM-355, a precipitation-hardening stainless steel, were found to be highly dependent upon carbide morphology. Corrosive attack in salt spray could always be associated with carbide precipitation at matrix discontinuities such as austenite or delta-ferrite grain boundaries. Continuous carbide precipitation at austenite grain boundaries was found to promote stress-corrosion failures in salt spray and to adversely affect certain mechanical properties such as ductility and impact strength.

Available in PDF, EPUB and Kindle. Book excerpt: Materials science is the magic that allows us to change the chemical composition and microstructure of material to regulate its corrosion-mechanical, technological, and functional properties. Five major classes of stainless steels are widely used: ferritic, austenitic, martensitic, duplex, and precipitation hardening. Austenitic stainless steels are extensively used for service down to as low as the temperature of liquid helium (-269oC). This is largely due to the lack of a clearly defined transition from ductile to brittle fracture in impact toughness testing. Steels with ferritic or martensitic structures show a sudden change from ductile (safe) to brittle (unsafe) fracture over a small temperature difference. Even the best of these steels shows this behavior at temperatures higher than -100oC and in many cases only just below zero. Various types of stainless steel are used across the whole temperature range from ambient to 1100oC. This book will be useful to scientists, engineers, masters, graduate students, and students. I hope readers will enjoy this book and that it will serve to create new materials with unique properties.
Download or read book Precipitation Hardening written by J. W. Martin and published by Butterworth-Heinemann. This book was released on 2012-12-02 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precipitation Hardening (or age-hardening) is an important technique for the metal-using industries. The process is used to enhance the mechanical properties of a wide range of alloys, notably those based on aluminium, but also embracing some nickel and other non-ferrous alloys as well as certain steels. It is important that the mechanisms that produce this improvement in properties are understood so that the desired properties can be optimised. This book provides a thorough treatment and grounding in the subject for the student of materials science and engineering, as well as guidance, for those using the process in industry and in research. A number of excerpts from classic papers are included, which illustrate the development of precipitation hardening from being an art to a science.Precipitation Hardening (or age-hardening) is an important technique for the metal-using industries.

Download or read book Effect of Composition and Section Size on Mechanical Properties of Some Precipitation Hardening Stainless Steels written by H. W. Garvin and published by . This book was released on 1965 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications have developed in which the high-strength properties associated with precipitation hardening stainless steel alloys are of considerable interest in large and medium section sizes. In a number of instances, transverse loading is involved. In common with other high strength materials, ductility in the transverse direction is lower than in the longitudinal direction. This paper presents transverse tension data obtained on a number of these alloys which serve to define this characteristic in a variety of shapes and sizes. The alloys discussed are 17-7 PH, PH 15-7 Mo, PH 13-8 Mo, 17-4 PH, and 15-5 PH. It is demonstrated that structural characteristics, particularly delta ferrite and certain precipitates, markedly influence transverse ductility and, in large section of 17-7 PH and PH 15-7 Mo, longitudinal ductility. Vacuum remelting does not help the directional ductility characteristics in compositions in which delta ferrite is a major controlling factor. Alloys in which composition changes have been incorporated to vary these structural factors have been developed. One of these is PH 13-8 Mo which is a composition employing aluminum as a hardening agent in which the analysis is adjusted to eliminate delta ferrite. This steel has excellent transverse ductility, especially in products made from double vacuum melted ingots. Another new material which has been called 15-5 PH contains copper as a hardening agent and is free of delta ferrite. In this modified composition the transverse ductility across the dead center of large sections is somewhat inferior to the transverse ductility obtainable at intermediate and surface locations in products made from air-melted ingots. Consumable electrode vacuum remelting eliminates the lower dead center transverse ductility in delta ferrite free products, such as 15-5 PH, by minimizing gross segregation, and excellent transverse ductility is obtained in any location.

Available in PDF, EPUB and Kindle. Book excerpt: Ferrous materials have made a major contribution to the development of modern technology. They span a tremendous range of properties and applications. Part A of this book is dedicated to the fundamental relationships between the structure and the properties of ferrous materials. The considerably larger Part B deals with standardised materials, recent developments and industrial applications, which also affect processing aspects. Details are given for general engineering materials, tool and functional materials, as well as high-strength, creep-resistant and wear-resistant grades. This book closes the gap in the treatment of steel and cast iron. Each chapter takes into account the gradual transitions between the two types of ferrous materials. The authors demonstrate that steel and cast iron are versatile and customisable materials which will continue to play a key role in the future.
