42 copper zinc phase diagram

Metals like silver and gold have a difference of 0.2%; nickel and copper of 2.7%, and show complete solid solubility. But zinc and copper have 4.2% difference with maximum solubility of 38.4 wt.% Zn. (other factors are less favourable); Cadmium in copper with 16.5% size difference shows a solid solubility of 1.7 wt.%. This article is a compilation of ternary alloy phase diagrams for which copper (Cu) is the first-named element in the ternary system. The other elements are Fe, Mn, Ni, Pb, S, Sb, Si, Sn, Ti and Zn. The diagrams are presented with element compositions in weight percent.

From the copper zinc phase diagram we can see the solid solubility of zinc in copper for concentrations of zinc upto about 30 at at equilibrium the alloy should be of a single phase. Note that each single phase field is separated from other single phase fields by a two phase field. Lecture 19 binary phase diagrams 6 of 16 112305.

Document includes crystal data for the Copper-Silicon-Zinc system, allotropic transformation data, and related references. Commercial brasses are copper-rich copper-zinc alloys. For example, cartridge brass is 70 wt% copper-30 wt% zinc 15 16 The magnesium-lead phase diagram: like two simple eutectic diagrams joined back to back Intermetallic compound (with distinct chemical formula), NOT a solid solution. Alpha copper is the primary phase in cast alloys containing up to approximately 40% zinc. The beta phase,which is the high zinc phase, is the minor constituent filling in the areas between the alpha dendrites. The microstructure of brasses containing up to approximately 40% zinc consists of alpha dendrites with beta surrounding the dendrites. The copper-zinc phase diagram shown in Fig. 9.2 contains intermedi-ate phases with appreciable ranges of solid solubility. In this diagram, the copper-rich α solid solution and the zinc-rich η solid solution are the two terminal phases, and the four intermediate phases are β, γ, δ, and ε. The

The single phase alpha brasses, containing up to about 37% zinc, are very ductile and easy to cold work, weld and braze. The dual phase alpha-beta brasses are usually hot worked. There are many brasses, with properties tailored for specific applications by the level of addition of zinc. Minor amounts of other alloying elements may also be added.
