TL;DR: In this article, the authors focused on the determination of transient mold-environment and metal-mold heat transfer coefficients during solidification using the expedient of comparing theoretical and experimental thermal profiles and applied both to pure metals and metallic alloys.

TL;DR: In this paper, analytical expressions have been developed describing thermal gradients and tip growth rate during one-dimensional unsteady-state solidification of alloys, and the correlation of these expressions with experimental equations relating mechanical properties and dendrite spacings provides an insight into the preprogramming of solidification in terms of casting mechanical properties.

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 paper, the Bouchard-Kirkaldy (BK) equation relating secondary spacings with tip growth rate has been used to determine the dendritic sparsities of Sn-Pb and Al-Cu alloys.
