The production process was the Fray-Farthing-Chen (FFC) Cambridge Process, which was the direct electrochemical reduction of ZrO2 to zirconium metal in molten CaCl2-CaO (900) and was carried out by Fray et al [3].
The formation of calcium chromites and titanates were observed during the electro reduction of their oxides by Fray et al [13-16].

Step 4 According to the calculated ve and vl of each APS, calculate the early start time (ee) and late start time (el) of each edge (0≤ i, j ≤n-1).
If the ee of an edge is equal to its el, the edge will be tagged as an edge of the longest path.

Structure and Phase Composition of Ni-Al-Co-Mе-Based Alloy Containing Rhenium and Ruthenium E.L.
The alloy under study contained other elements apart from Ni, such as: Al, Co, and also Mo, Cr, W, Ta, Re, and Ru.
The other elements, like Al and Ta, by contrast, are concentrated in g¢-phase [17-31].
These are: d-phase (Al3Ta3Ru), Laves phase (Ta3Ni2Cr2Co) and s-phase (Ni,Co,Al,Re)x(Cr,Mo,Ta,W)y.
