“…6e). This supports the experimental work [8] and the thermodynamic calculations [22]. Additionally, the (Al 8 Cr 5 ) h phase was detected as primary crystallized phase at the alloy composition 57Al-15Ti-28Cr ( Fig.…”

“…In these reviews, liquidus surfaces, various complete and partial isothermal sections in the temperature range 770 -1473 K, and reaction schemes were presented. Three thermodynamic descriptions of the ternary AlTi-Cr system [21][22][23] have been developed based on extensive literature reviews of existing phase equilibria data. However, the construction of the solidus projection as well as the analysis of the phase equilibria just below the solidus temperatures for Al contents < 75 at.% was not presented yet.…”

“…This phase only solutionizes above 1365° C and was thus retained during the solutionization treatments. Even bove the 1365° C martk, it has been reported to require longer solutionization times to dissolve [7,9].…”

“…Overall, the phase stability in the Ti-rich side of the system is well studied, as reviewed by Murray [6] and Cupid et al [7]. Figure 0.2 shows the equilibrium phase diagram of the system given by Cupid, et al showing the eutectoid at 686° C and 12 wt% Cr [7]. When quenched from the β phase field, Ti-rich portions form martensite of α.…”

“…Murray also states that "these structures can be described as different stacking sequences of the same basic cell, and small amounts of one phase may easily be interpreted as stacking fault variants of another" [6]. For this reason, the Laves phase compound region is still largely regarded as speculative [6,7]. Also leading to difficulty regarding the behavior of the formation of these Laves phases is that they do not form immediately upon ageing in the α+TiCr2 phase field.…”

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

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.
