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 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 کاملEffect of a weak transverse magnetic field on the microstructure in directionally solidified peritectic alloys
Effect of a weak transverse magnetic field on the microstructures in directionally solidified Fe-Ni and Pb-Bi peritectic alloys has been investigated experimentally. The results indicate that the magnetic field can induce the formation of banded and island-like structures and refine the primary phase in peritectic alloys. The above results are enhanced with increasing magnetic field. Furthermor...
متن کاملInfluence of Growth Rate and Magnetic Field on Microstructure and Properties of Directionally Solidified Ag-Cu Eutectic Alloy
We report the influence of growth rate and external magnetic field on the eutectic lamellar spacing and properties of directionally-solidified Ag-Cu eutectic alloys. The results indicated that the relationship between the lamellar spacing of directionally-solidified Ag-Cu alloys and the growth rate matched the prediction of the Jackson-Hunt model, and the constant was 5.8 µm³/s. The increasing ...
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...
