Fig.1 Schematics of electrode placement in the triple vacuum arc remelting (VAR) process (The first smelting uses a homogeneous electrode, denoted by A. When the previous ingot is placed upright as an electrode, it is represented by D; when the previous ingot is placed upside down as an electrode, it is represented by R) (a) VAR1-A (b) VAR2-D (c) VAR2-R (d) VAR3-D-D (e) VAR3-D-R (f) VAR3-R-D (g) VAR3-R-R
