Calculation Of Phase Composition Of Castable High-temperature Corrosion-resistant Nickel Alloy By Using CALPHAD Method

Automated designing of manufacturable high-temperature alloy composition on nickel base for manufacture of all-cast nozzle apparatuses

“…On November [21][22][23][24]2017, the XVI International Forum was held in Kiev at the International Exhibition Center. Starting from 2005, the Forum has been included into the list of leading world industrial exhibitions, officially certified and recognized by UFI -the Global Association of the Exhibition Industry.…”

“…Initially, a computer experiment was used to carry an evaluation of structural stability of the computed compositions in a set range of variation by indicated elements on N v γ , M d γ , M d C and ΔE parameters using traditional methods following known regression equations (RE) [1-4, 6, 7, 13-20] as well as mathematical regression models (RM) in accordance with the algorithm (see Figure) of developed CASM method [12,[21][22][23][24].…”

“…traditional computation methods PHACOMP (N n ) [7,11], New PHACOMP (M d ) [13], DE-method [14][15][16][17] with their known regression equations (RE) as well as received mathematical regression models (RM) [12,[21][22][23][24] (Table 3). Computations using CALPHAD method [25] on structural-phase and physical parameters [24,26] were carried out based on criteria (parameters) of serviceability of cast HNA, grounded on works [12,[21][22][23][24]. Tables 4 and 5 represent the computed values of structural-phase and physical parameters for designed alloy ZhS3LS-M of the optimum doping level.…”
