TL;DR: In this article, the effect of Zr content on microstructure and corrosion resistance of Ti-30Nb-Zr as-cast alloy samples has been investigated in a 0.9% NaCl (0.15 mol l −1 ) solution at 25 °C and neutral pH range.

TL;DR: In this paper, a comparative evaluation of as-cast Sn-Bi, Sn-Ag and Sn-Zn alloys as a function of the resulting microstructural arrays with a view to application as solder materials is presented.

TL;DR: In this article, the authors investigated the influence of heat transfer solidification variables on the microstructural array of both Al 9 wt pct Si and Zn 27 pct Al alloy castings and developed correlations between the as-cast dendritic microstructure, corrosion potential, and tensile mechanical properties.

TL;DR: In this paper, the effects of two different heat treatments, furnace cooling and water quenching, on the general electrochemical corrosion resistance of Ti-35wt%Nb alloy samples immersed in a 0.9% NaCl solution at 25°C and neutral pH range were investigated.

TL;DR: In this article, the relationship between mechanical properties, microstructure and solidification variables of Zn-Al alloys castings has been studied and theoretical dendritic growth models, expressing secondary spacings as function of tip growth rate or local solidification time have been tested against experimental data obtained during unsteady-state solidification.
