Investigation of the Undercoolability of Ni-Based Alloys Using High Temperature Thermal Analysis

open access: yesMetals, 2015
During the single crystal (SX) solidification of turbine blades, grain defects can form in the platform regions which have abruptly varying cross-sections.

The selection of Saffman-Taylor fingers by kinetic undercooling [PDF]

open access: yes, 2003
The selection of Saffman-Taylor fingers by surface tension has been widely studied. Here their selection is analysed by another regularisation widely adopted in studying otherwise ill-posed Stefan problems, namely kinetic undercooling.

Microstructure evolution in undercooled Ag-50at. %Cu hypereutectic alloy

open access: yesJournal of Materials Research and Technology, 2023
Ag–Cu alloys, as one type of typical eutectic solders, have been widely used in microelectronic packaging. The welding performance of Ag–Cu solders is closely associated with their microstructures.

An Interesting Case of Undercooling [PDF]

open access: yes, 1947
Whenever the subject of undercooling of a liquid is taken up in a physics text, some such statements as those quoted appear in the discussion. The difficulties of getting a successful mass demonstration of the undercooling of water are well known.

Soft Modes in Undercooled Liquids [PDF]

open access: yesEurophysics News, 1993
Abstract Recent studies of soft vibrational, tunneling and relaxational modes in glasses support the validity of the soft potential model, an extension of the tunneling model. The implications of this validity are investigated for the undercooled liquid.

Asymptotic Solutions of Steady Lamellar Eutectic Growth in Directional Solidification for Small Tangent Values of the Contact Angles

open access: yesCrystals
A system of steady lamellar eutectic growth in directional solidification is considered with the case of small tangent values of the contact angles. The mathematical model is given in the non-dimensional rectangular coordinate system and the uniformly ...

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Study of Undercooling and Recalescence During Solidification of Sn62.5Pb36.5Ag1 and Sn96.5Ag3Cu0.5 Solders in Real Electronic Joints [PDF]

open access: yes, 2014
Undercooling and recalescence were studied using the differential scanning calorimetry (DSC) method on real electronic systems. Two solder pastes, Sn62.5Pb36.5Ag1 and Sn96.5Ag3Cu0.5, were used for preparation of electronic joints. Various combinations
