Dudu Dada Didi Dodo Dede Youtube From that we have chosen two alloys, the cu 30 dy 70 (t melt = 790 °c) and the cu 60.5 dy 39.5 (t melt = 840 °c) composition to look in detail at the influence of the view in full text get. The following feature of cu 7 dy 2 must be examined also: this phase forms from l and cu 9 dy 2 by a peritectic reaction at 935 °c and decomposes into the original phases on cooling by a catatectic reaction at 854 °c. this feature requires extremely delicate balance in the thermodynamic properties of the phases involved.
Dvd Du Dudu E Edu Completo Dublado Frete Grátis R 40 00 Em The crystal structure of cu 7 dy 2 was unknown for a long time, and cu 9 dy 2 was assigned to have a tetragonal structure by franceschi. recently, cerny et al. [3] have reported a new compound, cu 4 dy, and structural models for cu x dy (x = 4.5, 4.0, 3.5) compounds. interestingly, these structure models contain 7448, 1248 and 480 atoms in the. Because the experimental data were scarce, the phase diagram was constructed by thermodynamic modeling based on assumed similarity of this system to cu gd, cu dy, and cu er systems. the phase diagram of [1988sub] was revised by [2009wan] by taking into account new literature data on the thermodynamic properties. The cu–dy binary system has been thermodynamically assessed with calphad approach. the solution phases including liquid, bcc, fcc and hcp were treated as substitutional solution phases, of which the excess gibbs energies were formulated with redlich–kister polynomial functions. the binary intermetallic compounds were treated as. The dy free and dy containing sintered magnets, with at.% compositions of nd 14.5 fe 78.1 co 1.0 cu 0.2 b 6.2 and nd 10.8 dy 3.7 fe 78.1 co 1.0 cu 0.2 b 6.2 (9 wt% dy), were prepared by a.

The dy cu system was examined using differential thermal analysis, micrography and x ray analysis. six intermediate phases were found to exist, of which three melt congruently (dycu at 955 °c. The isothermal section at 700 °c (fig. 2) has no experimental support. besides the changes in the stability of the binary phases, two solid state u type transition reactions occur between 700 and 500 °c: cudy τ 3 ↔ cu 2 dy τ 7 and τ 4 (al) (or l) ↔ αal 3 dy τ 1. fig. 1. al cu dy computed isothermal section at 500 °c [ 2009zha ].
