Growth directions in directionally solidified Al–Zn and Zn–Al alloys near eutectic composition
Growth directions and crystallographic orientations of solidification microstructures have been measured in Al–Zn alloy near the eutectic composition. Al dendrites in Al–92 wt.% Zn alloy were found to grow along the h110i directions while Zn dendrites in Al– 96 and 98 wt.% Zn have h10 10i trunks. In the lamellar eutectic, a crystallographic relationship has been found between the dense plane of...
متن کاملFormation of equiaxed crystal structures in directionally solidified Al-Si alloys using Nb-based heterogeneous nuclei
The design of chemical compositions containing potent nuclei for the enhancement of heterogeneous nucleation in aluminium, especially cast alloys such as Al-Si alloys, is a matter of importance in order to achieve homogeneous properties in castings with complex geometries. We identified that Al3Nb/NbB2 compounds are effective heterogeneous nuclei and are successfully produced in the form of Al-...
متن کاملMagnetomechanical performance of directionally solidified Fe–Ga alloys
Iron-gallium alloys can produce magnetostrictions of 400 ppm and might serve as mechanically robust actuator/sensing materials. However, for polycrystalline Fe–Ga alloys, the magnetostrictive performance decreases with the increasing deviations from the ideal 100 texture. In this paper, three directionally solidified Fe–Ga alloys with gallium contents of 17, 18.4, and 19.5 at. % were characteri...
متن کاملPrecipitation in a Ni - Al - Mo Directionally Solidified Eutectic Composite
The most recently developed high temperature materials are known as in-situ composites or directionally solidified eutectics. Since the composites are formed during solidification, they have excellent morphological stabilities up to near their melting temperatures. The Ni-Al-Mo system has received the greatest attention for recent several years(1)~(3) since the alloy is expected to form a struc...
متن کاملMicrostructure of Al-Zn and Zn-Al Alloys*
The change of microstructure of the title alloys with concentration, temperature and applied thermal treatment was studied in situ by XRD. The alloys, having the Zn atomic fraction, x(Zn), from 0.03 to 0.62, were subjected to: (i) rapid quenching from a temperature, Tt, higher than the solid-solution temperature, Tss, in water at RT (samples WQ); (ii) slow cooling from Tt to RT (samples SC). Th...
