Rapid solidification behavior of Zn-rich Zn–Ag peritectic alloys
Rapid solidification experiments, including laser remelting, melt-spinning and wedge casting, were carried out to investigate the rapid solidification behavior of Zn-rich Zn–Ag peritectic alloys containing up to 9.0 at% Ag. For comparison, Bridgman solidification experiments of the same alloys were also carried out for growth velocities ranging from 0.02 to 4.82 mm/s, which were lower than that...
متن کاملMathematical and Physical Modelling of Directional Solidification of Aerospace Alloys
Defect formation in aerospace components is studied, particularly in regions of directionally solidified casting with stepwise increase in cross-section, which is a typical geometric configuration for such components as turbine blades. Given the fact that the geometry of a casting is directly related to probability of defect formation, special attention was paid to grain defects in regions of c...
متن کاملCrossover scaling of wavelength selection in directional solidification of binary alloys.
We simulate cellular and dendritic growth in directional solidification in dilute binary alloys using a phase-field model solved with adaptive-mesh refinement. The spacing of primary branches is examined for a wide range of thermal gradients and alloy compositions and is found to undergo a maximum as a function of pulling velocity, in agreement with experimental observations. We demonstrate tha...
متن کاملPeritectic phase transformation in the Fe–Mn and Fe–C system utilizing simulations with phase-field method
The present investigation focuses on the solidification of peritectic binary alloys in the systems Fe–Mn and Fe–C by utilizing phase-field simulations. Isothermal and directional solidification conditions were simulated with this approach and the following aspects were investigated: the phases evolution during the peritectic transformation close to the peritectic temperature for the Fe–Mn alloy...
متن کاملDirect formation of peritectic phase but no primary phase appearance within Ni83.25Zr16.75 peritectic alloy during free fall
Ni83.25Zr16.75 peritectic alloy was containerlessly solidified in a drop tube. When the droplet diameter exceeds a critical value (Dcrit), Ni7Zr2 phase primarily solidifies, followed by the peritectic reaction of Ni7Zr2 + L → Ni5Zr. Once the droplet diameter is smaller than the critical value (Dcrit), peritectic phase Ni5Zr directly solidifies from the undercooled melt by completely suppressing...
