Contribution a l'etude du systeme ternaire aluminium-zinc-etain

Abstract

This work is a study of the L~2 S and S ~-S equilibria in the ternary system AI--Zn--Sn. The diagram has been established by an isopleth cutting method using coupled direct and differential thermal analysis and an electron probe microanalyser. This study has permitted: --

Contribution to the study of the Al-Zn phase diagram

“…In summary, the present calorimetric investigations rule out the existence of an e"-phase and of a second monotectoid reaction at 340 ~ These findings are in accord with ternary phase diagrams involving the AI-Zn system [14]. The very strong heat effect which accompanies the transformation Qfcc + ~hex ~ (~'fcc is probably due to the transformation energy of hexagonal zinc to a fcc structure, in which form it exists in the region above the miscibility gap.…”

Thermodynamics of liquid Al–Sn–Zn alloys and concerned binaries in the light of soldering characteristics

“…The CSRO parameter, a 1 have been calculated following Eq. (13). w and Z are basic inputs for the calculations.…”

“…Aluminium [12] is one of the suitable candidates. Because of the particular nature of aluminium, extensive investigation of the phase diagram [13], microstructures [3] and oxidative properties [14], and thermodynamic properties [15] of Al-Sn-Zn system has been carried out. But the understanding of the energetics of the system is necessary for solder applications.…”

Thermodynamic Properties of Liquid Al-Sn-Zn Alloys: A Possible New Lead-Free Solder Material

“…The ternary phase diagram was studied by Vicent and Seboun 12,13,41,42) and a critical evaluation of different reported investigations is given by Hubert-Protopopescu and Hubert. 15) Standard CALPHAD procedures were used to as- Fig.…”

“…11) Extensive experimental studies of the ternary phase diagrams were carried out by Vincent and Sebaoun 12) and Sebaoun et al 13) An assessment of the Al-Sn-Zn system was carried out by Fries et al 14) and an evaluation of all the literature data is given by HubertProtopopescu and Hubert.…”
