چکیده
The morphologies of intermetallic phases (IMCs) during directional solidification the Sn-Cu (L+Cu3Sn→Cu6Sn5) and Sn-Co (L+CoSn→CoSn2) peritectic systems were analyzed. primary Cu3Sn Cu6Sn5 in alloy are IMCs whose solubility ranges narrow, while both CoSn CoSn2 nil equilibrium condition. experimental results before acid corrosion shows that dendritic morphology can be observed. investigation on local after deep these dendrites composed small sub-structures with faceted feature. Faceted growth is also confirmed, a to non-faceted transition their observed increasing velocities. Further analysis formed solidified range larger solidification.

Competition of the primary and peritectic phases in hypoperitectic Cu–Sn alloys solidified at low speed in a diffusive regime
Directional solidification experiments on hypoperitectic Cu–Sn alloys have been performed at very low velocity in a high thermal gradient to ensure planar front growth of both phases. The diameter of the sample has been reduced to 500 lm to strongly reduce convection. Lamellar and fibrous peritectic cooperative growth of the primary aand peritectic b-phases has been observed on length spanning ...
متن کاملThe Kinetics of Formation of Ternary Intermetallic Alloys in Pb-Sn and Cu-Ag-Sn Pb-free Electronic Joints
A simple model of the formation of Au0.1Ni0.1Sn0.8 in Pb-Sn solder/Ni interconnects is examined by numerical simulation. Previous experimental observation has shown that after reflow the interface consists of the Ni3Sn4 alloy between Pb-Sn solder and Ni, with Au distributed through the PbSn solder ball. Au0.1Ni0.1Sn0.8 was observed to form at the Pb-Sn solder/Ni3Sn4 interface during annealing a...
متن کاملApplication of single pan thermal analysis to Cu–Sn peritectic alloys
Single pan thermal analyses (SPTA) have been performed on Cu–14.5 wt.% Sn, Cu–21.3 wt.% Sn and Cu–26.8 wt.% Sn peritectic alloys. For this purpose, a SPTA assembly has been built and calibrated. As the latent heat is a function of temperature and composition during solidification of alloys, a new heat flow model coupled to a Cu–Sn thermodynamic database has been defined for the calculation of t...
متن کاملCu-Sn Intermetallic Compound Growth in Hot-Air-Leveled Tinat and below 100°C - Tyco Electronics
Low-temperature intermetallic compound (lMC) growth in hot-air-leveled tin (HALT) at lower temperatures was investigated. A technique based on image analysis of backscatter electron scanning electron microscopy images was used to measure the average thickness of Cu-Sn IMC in HALT at 50°C, 75°C, and 100°C with a high degree of precision. The technique made it possible to observe new features of ...
متن کاملInfluence of electric current pulses on the solidification of Cu-Bi-Sn immiscible alloys
Continuous solidification experiments were carried out with Cu-Bi-Sn alloys under the effects of Electric Current Pulses (ECPs). A model describing the microstructure evolution was developed. The formation of the microstructure in the continuously solidified alloys was calculated. The calculations demonstrated that ECPs mainly affect the solidification process through changing the energy barrie...
