Segregation and temperature effect on the atomic structure of Bi₃₀Ga₇₀liquid alloy

Abstract

We investigate the structure of liquid monotectic alloy Bi(30)Ga(70) above and below the critical point. The three-dimensional structure at 265 °C is modelled by means of the reverse Monte Carlo simulation technique using neutron and x-ray diffraction experimental data. It is shown that atomic segregation on the short-range scale exists in the liquid Bi(30)Ga(70) slightly above the critical temperature (T(C) = 262 °C). We present also the structure factors of Bi(30)Ga(70) liquid alloy under the critical point at 240 and 230 °C obtained with neutron diffraction to highlight the temperature effect in the atomic structure.

Electrical Transport and Electronic Structure Calculation of Al-Ga Binary Alloys

“…Since the past few decades, Al, Ga and their alloys of very high purity have begun to play a pivotal role as materials for wide industrial use [1][2][3][4][5][6]. Straumal et al studied the grain growth in high purity Al-Ga alloys at various Ga-concentrations.…”

Structure and Electrical Resistivities of Liquid Al and Ga Metals and Their Binary Alloys

“…In this study, we have calculated electrical resistivities using the modified Ziman formula suggested by Ferraz-March for Al 1−x Ga x liquid metal alloys at 973 K. We have selected Al-Ga alloys in this study because Al, Ga, and their alloys play pivotal roles as materials for wide industrial use [4][5][6][7][8][9], and their structural and transport properties have been recently investigated theoretically at the same temperatures [10]. To describe interionic interactions, we have used the individual version of the local pseudopotential proposed by Fiolhais et al [11,12] which was developed for the solid state in requiring the main electronic features to be correctly predicted, and could be transferable to other environments as tested for liquid binary metal alloys [13][14][15][16][17][18][19].…”
