Growth directions in directionally solidified Al–Zn and Zn–Al alloys near eutectic composition
نویسندگان
چکیده
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 each phase, i.e. f111gfcck f0001ghcp, and the dense directions, i.e. h110ifcckh1 210ihcp. 2008 Acta Materialia Inc.

Different compositions of Al–Cu alloys were directionally solidified upward with constant growth rate (V>18?6 mm s) and constant temperature gradient (G>4?7 K mm) using a Bridgman type growth apparatus. The variations in electrical resistivity r with temperature for directionally solidified Al–Cu alloys were measured in the range of 3732773 K using a standard four-point probe technique. Accordi...
متن کاملTwinned dendrite growth in binary aluminum alloys
The formation of twinned dendrites (feathery grains) in binary Al–Zn, Al–Mg, Al–Cu and Al–Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G 100 K cm , v 1 mm s , and with slight natural convection in the melt. The influence of the solute element nature and content has been found to be of less importance than previously reported since fea...
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 ...

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-...
