Available in PDF, EPUB and Kindle. Book excerpt: Several authors have emphasized that aluminum nitride in iron and iron alloys not only lowers the transition temperature but also suppresses the rise of the transition temperature due to irradiation. To clarify the mechanism of the effect of aluminum nitride, structural changes after irradiation and annealing are observed by means of internal friction and electron microscopy. Materials investigated are iron, containing 0.05 wt% Al and 0.01 wt% N with 1 ppm C and a few ppm 0, and iron, containing 0.02 wt% Al and 0.005 wt% N with 10 ppm C and 20 ppm 0. The materials are annealed at 750 C before irradiation and irradiated in the JRR-2 at temperatures of 60 C and up to 1.2x1019 n/cm2, E 1 MeV. Two new peaks in internal friction are found at ~125 C and ~155 C after irradiation. Besides these changes a new type of precipitate is observed by electron microscopy. These precipitates are thin, doughnut shaped disks with a diameter of 0.3 ?m and are considered to be complex defects of irradiation induced point defects, nitrogen, and aluminum atoms. The 125 C peak of internal friction disappears after annealing at 250 C for 30 min; the 150 C peak disappears after annealing at 150 C for 30 min or aging at room temperature for about half a year. Resolution of free nitrogen is observed, but precipitates do not disappear even after annealing at 350 C for 30 min. The precipitates suppress the formation of irradiation induced complex nitrogen defects and irradiation hardening because of the strong effect of aluminum on nitrogen atoms.

Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Materials Science and Technology, Volume 25: Embrittlement of Engineering Alloys is an 11-chapter text that describes some situations that produce premature failure of several engineering alloys, including steels and nickel- and aluminum-base alloys. Chapters 1 to 3 consider situations where improper alloy composition, processing, and/or heat treatment can lead to a degradation of mechanical properties, even in the absence of an aggressive environment or an elevated temperature. Chapters 4 and 5 examine the effect of elevated temperatures on the mechanical properties of both ferrous and nonferrous alloys. Chapters 6 and 7 discuss the effects of corrosive environments on both stressed and unstressed materials. In these environments anodic dissolution is the primary step that leads to failure. Chapters 8 to 10 deal with the effects of aggressive environments that lead to enhanced decohesion or embrittlement of the metal, such as hydrogen, liquid metal, and irradiation-induced embrittlement. Chapter 11 looks into the embrittlement phenomena occurring during welding, one of the most common processing conditions to which a material could be subjected. This book will prove useful to materials scientists and researchers.
