“…Table 2 lists the grain size averages of the different processing types as determined by the OIM software over surface areas containing 2000 or more grains. Although the sizes for the extruded and rolled materials are slightly larger than those reported by Vettraino et al [7] the same trends are still observed. The disparity between data presented is caused in part by difficulties of accurately distinguishing subgrain boundaries from true grain boundaries in the visual inspection methods used by Vettraino et al [7].…”

“…Samples for electron backscatter diffraction (EBSD) and orientation image mapping (OIM) were epoxy mounted and mechanically polished through a final polishing step using 0.05 m colloidal silica on Struers MD Nap, followed by an electro-polish in 50 vol% phosphoric acid and 50 vol% water solution at room temperature [7]. The electro-polishing parameters were 12V dc in an agitated solution using a stainless steel cathode for approximately 20 s. EBSD acquisition was conducted at the Los Alamos National Laboratory (LANL) on a Phillips FEI XL30 FEG-SEM, operating at 25 kV, using the EDAX TSL-OIM software package.…”

“…The analysis of the Kikuchi orientation lines of the copper matrix was conducted using standard Hough pattern recognition. These data were compared with data collected using the same method for the extruded and rolled material forms [7]. For all three material types, the constraints used for distribution analysis were that a grain must consist of at least five data points with no more than 5 • of misorientation between adjacent points.…”

“…For this study, the grain morphology and texture of the annealed material were compared to those of the extruded and rolled materials which were described in detail by Vettraino et al [7]. The FSW sample was not analyzed via OIM because the subsequent microstructure apparently does not affect creep rate and the loss of creep ductility can be attributed to strain localization in the softer heat-affected zone.…”

Laves phases: a review of their functional and structural applications and an improved fundamental understanding of stability and properties

2020

View full text Add to dashboard Cite

Laves phases with their comparably simple crystal structure are very common intermetallic phases and can be formed from element combinations all over the periodic table resulting in a huge number of known examples. Even though this type of phases is known for almost 100 years, and although a lot of information on stability, structure, and properties has accumulated especially during the last about 20 years, systematic evaluation and rationalization of this information in particular as a function of the involved elements is often lacking. It is one of the two main goals of this review to summarize the knowledge for some selected respective topics with a certain focus on non-stoichiometric, i.e., non-ideal Laves phases. The second, central goal of the review is to give a systematic overview about the role of Laves phases in all kinds of materials for functional and structural applications. There is a surprisingly broad range of successful utilization of Laves phases in functional applications comprising Laves phases as hydrogen storage material (Hydraloy), as magneto-mechanical sensors and actuators (Terfenol), or for wear- and corrosion-resistant coatings in corrosive atmospheres and at high temperatures (Tribaloy), to name but a few. Regarding structural applications, there is a renewed interest in using Laves phases for creep-strengthening of high-temperature steels and new respective alloy design concepts were developed and successfully tested. Apart from steels, Laves phases also occur in various other kinds of structural materials sometimes effectively improving properties, but often also acting in a detrimental way.
