Powder Metallurgy Stainless Steels

Abstract

Powder Metallurgy Stainless Steels: Processing, Microstructures, and Properties covers every step in the production of powder metal stainless steel parts, examining the effect of each processing variable on corrosion resistance as well as strength, ductility, and other properties. It provides a brief history of the technology and an overview of the metallurgy and composition of wrought and powder stainless steels. It explains how powders are made and how they are characterized based on chemical composition, particle size and shape, compressibility, and other factors. It describes compacting and shaping methods, including rigid die compaction, metal injection molding, extrusion, and hot isostatic pressing, and discusses several sintering processes, explaining how furnace atmosphere, heating and cooling rates, and part density affect property development and corrosion resistance. It also covers secondary operations such as machining, welding, sinter bonding, and resin impregnation, describes the effect of thermal and deformation processes on creep, fatigue, and other mechanical properties, and explains how to evaluate and test corrosion performance. The book includes an atlas of microstructures, a glossary of terms, and detailed application examples. For information on the print version, ISBN: 978-0-87170-848-9, follow this link.
