Available in PDF, EPUB and Kindle. Book excerpt: Nonconventional heat treatments were designed to improve the mechanical properties of these martensitic steels. Results show that the as-quenched structures of both steels consist mainly of dislocated martensite. In the boron-free steel, there are more lath boundary retained austenite films. The boron-treated steel shows higher strengths at all tempering temperatures but with lower Charpy V-notch impact energies. Both steels show tempered martensite embrittlement when tempered at 350°C for 1 hour. The properties above 500°C tempering are significantly different in the two steels. While the boron-free steel shows a continuous increase in toughness when tempered above 500°C, the boron-treated steel suffers a second drop in toughness at 600°C tempering. Transmission electron microscopy studies show that in the 600°C tempered boron-treated steel large, more or less continuous cementite films precipitate at the lath boundaries, which are probably responsible for the embrittlement. The differences in mechanical properties at tempering temperatures above 500°C are rationalized in terms of the effect of boron-vacancy interactions on the recovery and recrystallization behavior of these steels. Boron seems to impair room temperature impact toughness at low strength levels but not at high strength levels. By simple nonconventional heat treatments of the present alloys, martensitic steels may be produced with quite good strength-toughness properties which are much superior to those of existing commercial ultra-high strength steels. It has also been shown that the as-quenched martensitic steels need not be brittle and in fact very good combinations of strength and toughness can be obtained with as-quenched martensitic steels. 56 fig., 5 tables, 75 references.

Download or read book Steels written by Robert William Kerr Honeycombe and published by John Wiley & Sons. This book was released on 1996-02-12 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of steels depend critically on their microstructure. By examining the mechanical properties of steels in conjunction with microstructure, the first edition gave a clear description of the development and behavior of these materials - the very foundation of their widespread use. This new edition more explicitly links this theory with applications while retaining the style and purpose of its predecessor.

Download or read book Steel Heat Treatment written by George E. Totten and published by CRC Press. This book was released on 2006-09-28 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of two self-contained volumes belonging to the newly revised Steel Heat Treatment Handbook, Second Edition, this book examines the behavior and processes involved in modern steel heat treatment applications. Steel Heat Treatment: Metallurgy and Technologies presents the principles that form the basis of heat treatment processes while incorporating detailed descriptions of advances emerging since the 1997 publication of the first edition. Revised, updated, and expanded, this book ensures up-to-date and thorough discussions of how specific heat treatment processes and different alloy elements affect the structure and the classification and mechanisms of steel transformation, distortion of properties of steel alloys. The book includes entirely new chapters on heat-treated components, and the treatment of tool steels, stainless steels, and powder metallurgy steel components. Steel Heat Treatment: Metallurgy and Technologies provides a focused resource for everyday use by advanced students and practitioners in metallurgy, process design, heat treatment, and mechanical and materials engineering.
