Microstructure 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...
متن کاملOn Some Ternary Phases in the Systems Nb-Zn-Al and Ta-Zn-Al
Aluminium, Niobium, Tantalum, Zinc, Alloy In the systems NbZi^-aALr and TaZn2_^Alz a great number of samples was prepared and investigated by means of X-ray powder diffraction. In both systems at the equiatomic composition two new ternary phases were found. Their crystal structures were determined and found to belong to the Friauf-Laves type (MgZm prototype, S. G. P 63/mmc). The unit cell param...
متن کاملGrowth 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 کاملTwo fluorescent Schiff base sensors for Zn(2+): the Zn(2+)/Cu(2+) ion interference.
Two simple and low cost 2,4-di-tert-butyl-6-[(1-hydroxycyclohexylmethylimino)methyl]phenol (L1) and 2-[{(1-hydroxycyclohexyl)methylimino}methyl]phenol (L2) Schiff base sensors exhibiting selectivity for Zn(2+) in water:methanol (95:5, v/v, 10 mM HEPES) are described. L1 and L2 display an "off-on" fluorescence effect forming the L1·Zn and L2·Zn complexes, respectively. In the case of L1·Zn, the ...
متن کاملShape Memory Properties in Cu-Zn-Al Alloy
In this research a Cu-Zn-Al alloy is produced by melting the raw materials in an electric resistance furnace and then pouring it into a steel mould. The optimum way to achieve the final analysis in the hypo-eutectoid range is determined and the influence of the alloying element, Ti on the grain size and the shape memory properties of the samples are investigated. Solution treatment (done at 850...
