Ti Cu Phase Diagram. 43 wt ni l. According to the phase diagram similar to the ti cu and ti ag alloys the ti au alloy has the eutectoid point with titanium.
Inorganic solid phases springermaterials online database springer heidelberg ed springermaterials cu ti binary phase diagram 0 100 at. An assessment of uncommon titanium binary systems. Cu and ni isomorphous ie complete solubility of one component in another.
According to cuti phase diagram the system has a eutectic temperature of 875 c.
The compound ti 2 cu 3 exists below 865 c and forms either at that temperature by the reaction ticu 2 ti 3 cu 4 2ti 2 cu 3 or at 850 c as a result of the decomposition of the compound ticu 2. Cu is bonded in a distorted body centered cubic geometry to eight equivalent ti atoms. Observant people may have noticed that the al cu phase diagram shown only goes up to around 60 by weight of copper. The early phase diagrams of the cuti system showed the terminal fcc cu rich solid solution α to be in equilibrium with a cu 3 ti phase characterized by a space group pnmm.
