This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a process contaminant, mercury is a significant problem due to its ability to induce liquid metal attack (LMA) and embrittlement (LME) in some alloys of construction. Aluminum alloys are particularly susceptible to LME. Several test methods (i.e., constant load tensile tests, fracture mechanics crack growth tests, and slow strain rate tests) were used to evaluate LME in aluminum alloys along with AISI 304 stainless steel. Additionally, the effect of various surface treatments on LME of aluminum alloys was also examined. This paper evaluates the effectiveness of the various testing techniques and results obtained in laboratory studies conducted in elemental mercury.

Available in PDF, EPUB and Kindle. Book excerpt: The role of plastic deformation in the initiation and propagation of cracks in Cu-17A1 alloy embrittled by liquid mercury has been studied. It is proposed that extensive plastic deformation and work hardening must occur at the crack-tip during propagation in order to raise the local flow stress to a critical level at which the maximum normal stress is equal to the cohesive strength. Strong indication is given that a 'critical applied stress' criterion for fracture is not applicable for this material. Micro-cracks are formed at weakened grain boundaries and a period of stable crack growth made over a period of increasing applied stress may be necessary before the crack is long enough to become unstable.

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.

This book was released on 1983 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crack growth rates were measured on three aluminum alloys under cyclic and static loading conditions in laboratory air and in liquid mercury at about +25 deg C. One alloy, 6061-T651, was tested under both loading conditions at temperatures ranging from -25 deg C to +45 deg C. Fracture mechanics techniques were used. Under cyclic loading conditions, no enhanced crack growth in mercury was measured until a critical stress intensity factor range (Delta K) was exceeded. When Delta K increased above the threshold value, the crack growth rae increased by as much as three orders of magnitude, when compared to the crack growth rate in air. From the appearance of the fracture surface the mechanism of embrittlement was deduced to be reduced cohesion. Under static loading conditions, crack velocities of centimeters per second were measured in load control. Under displacement control much slower crack velocities were measured in tow alloys. The decrease in crack velocity was attributed to crack blunting and large plastic zones. Static crack velocity and cyclic crack growth rate increased with decreasing temperature. This unusual temperature effect was related to the kinetics of adsorption of mercury on aluminum. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Crack growth rate measurements have been made in three mercury embrittled aluminum alloys each under three loading conditions. The alloys were 1100-0, 6061-T651, and 7075-T651. The loading conditions were fixed displacement static loading, fixed load static loading, and fatigue loading at two frequencies. The results showed that mercury cracking of aluminum was not unlike other types of embrittlement (i.e hydrogen cracking of steels). Under fixed load static conditions no crack growth was observed below a threshold stress intensity factor (KILME). At K levels greater that KILME cracks grew on the order of cm/s, while under fixed displacement loading, the crack growth rate was strongly dependent upon the strength of the alloy tested. This was attributed to crack closure. In the fatigue tests, no enhanced crack growth occurred until a critical range of stress intensity factor (Kth) was achieved. The Kth agreed well with the KILME obtained from the static tests, but the magnitude of the fatigue growth rate was substantially less than was expected based on the static loading results. Observations of the fracture surfaces in the scanning electron microscope (SEM) suggested a brittle intergranular fracture mode for the 6061-T651 and the 7075-T651 alloys under all loading conditions. The fractographic features of the 1100-0 alloy under fixed load and fatigue loading conditions were also brittle intergranular. Under fixed displacement loading the cracks grew via a ductile intergranular mode.
