Effect of solidification parameters on the microstructure of directionally solidified Sn-Bi-Zn lead-free solder
(KOREAN INST METALS MATERIALS, 2012)
Sn-Bi-Zn lead free solder alloy was directionally solidified upward at a constant temperature gradient (G=3.99 K/mm) with a wide range of growth rates (8.3-478.6 mu m/s) and at a constant growth rate (V=8.3 mu m/s) with a ...
Determination of Interfacial Energies for Solid Al Solution in Equilibrium with Al-Cu-Ag Liquid
(KOREAN INST METALS MATERIALS, 2010)
The equilibrated grain boundary groove shapes of a solid Al solution in equilibrium with Al-Cu-Ag liquid were observed from a quenched sample using a radial heat flow apparatus. The Gibbs-Thomson coefficient, solid-liquid ...
Dependency of Microstructural Parameters and Microindentation Hardness on the Temperature Gradient in the In-Bi-Sn Ternary Alloy with a Low Melting Point
(KOREAN INST METALS MATERIALS, 2008)
The ternary alloy In-21.5 at.% Bi-17.8 at.% Sn, which has a melting point of 60 degrees C, was directionally solidified upward with a constant growth rate (V = 3.2 mu m/s) and different temperature gradients (G = 0.91 K/mm ...
