Röntgenanalyse der Kupfer–Zinnlegierungen

Abstract: Ronlgmanalyse der Icupfer-Zinnlegierungen. 81 lungen bei hoherer Temperatur derjenigen Legierungen, die etwa 15--35O/, Sn enthalten, und drittens die Natur uud den Konzentrationsbereich derjenigen Phase, die bei einem Gehalt von etwa 60°/, Sn bei niedriger Temperatur gebildet wird. Dank der Untersuchungen einer groBen Anzahl von Forschern kennen wir jetzt das Zustandsdiagramm des Kupfer-Zinnsystemes mit einem verEaltnismaBig hohen Grade von Zuveryassigkeit. In dem in Fig. 1 wiedergegebenen Diagsamm sind die Er… Show more

“…The Sn rich Sn-Cu binary phase diagram, 10,11) shows that Cu 6 Sn 5 has two crystal structures, with an allotropic transformation at 186 C. For the compositions studied here, the high temperature hexagonalCu 6 Sn 5 phase is expected to form during solidification and to transform to the low temperature monoclinic 0 -(Cu,Ni) 6 Sn 5 0 phase on cooling. [11][12][13] The monoclinic Sn 49 Cu 49 Ni 2 intermetallic in Fig. 3 is consistent with the room temperature monoclinic 0 -(Cu,Ni) 6 Sn 5 0 phase.…”

“…In such alloys the second phase consists of acicular particles of CuSn (Farnham 1934) which possess a hexagonal crystal structure (Westgren & Phragmen 1928). Again on cyclic thermal treatm ent, deformation occurred as distortions in the regions of the grain boundaries of the matrix.…”

“…It was the subject of intense studies with the X-ray powder diffraction methods by Westgren and Phragmén in Sweden in the 1920's, and they were the first to draw attention to the electron concentration significance of the 'famous' 21/13 electron to atom ratio. 27) Also at about the same time, Hume-Rothery in England similarly emphasized the stabilizing electron concentration role in alloy phases and the value for the -brasses to be e=a ¼ 21=13 ¼ 1:615, characteristic of the two typical stoichiometric formulas in copper based alloys, Cu 5 Zn 8 and Cu 9 Al 4 , which he considered as being compound-like (for a more detailed historical account of these developments please see Ref. 28)).…”
