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 کاملSerrated flow in nanostructured binary Mg-Al alloys
Article history: Received 2 August 2016 Received in revised form 14 September 2016 Accepted 15 September 2016 Available online xxxx Serrated flow, also known as the Portevin-Le Chatelier effect, has been extensively investigated in binary Mg-alloys such asMg-Ag,Mg-Y andMg-Li alloys. Interestingly, however, this effect has not been observed inMg-Al alloys. In this work, we report the appearance ...
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 کاملCorrosion Mechanism of Al-zn-in Alloys in Chloride Solutions
The electrochemical behavior of Al-ZnIn alloys was investigated in chloride media by means of potentiodynamic techniques, complemented by Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Analysis (EDX) and Transmission Electron Microscopy (TEM). The influence of local alkalization produced by previous cathodization was analyzed at potentials more negative than the rest potential. The...
متن کاملDamping Capacity of Hypo-Eutectic Zn-Al Alloys
Damping capacity of hypo-eutectic Zn-Al alloys as a function of rolling ratio is investigated. Effect of heat treatment after cold rolling on the damping capacity is discussed. Damping tests were carried out using the method of the free decay of vibrations in bending oscillation. With an increase in rolling reduction, the damping capacity was increased. As the results of tensile and hardness te...
