“…The TA Instruments xenon-flash compact benchtop apparatus (Discovery Xenon Flash DXF-500) was used to measure thermal diffusivity from 25 to 250 °C. More information on the fundamental theoretical concepts and practical procedures underlying the used xenon-flash method can be found in [13][14][15][16][17]. The cast Cu-Bi alloy samples were machined into round disks (12.6 mm in diameter and 2 mm thick, with two ground plane parallel end-faces) before being annealed at 200 °C for 48 hours.…”

Thermal transport properties of solid Bi-Cu alloys have been investigated over a wide composition range and temperature range ranging from 25 to 250 °C. The flash method was used to determine thermal diffusivity. Thermal diffusivity was discovered to decrease continuously with increasing temperature and bismuth content. The indirect Archimedean method was used to determine the density of the Bi-Cu alloys at 25 °C. The obtained results show that the density of the studied alloys decreases slightly as the copper content increases. Thermal conductivity of the alloys was calculated using measured diffusivity, density, and a calculated specific heat capacity. The thermal conductivity of the studied Bi-Cu alloys decreases with increasing temperature and bismuth content, similar to thermal diffusivity. SEM with energy dispersive X-ray spectrometry (EDS) and differential scanning calorimetry (DSC) were used to examine the microstructure and melting behavior of Bi-Cu alloys, respectively. The eutectic temperature was measured to be 269.9±0.1 °C, and the measured phase transition temperatures and heat effects were compared to thermodynamic calculations using the CALPHAD method.

“…Phase transition temperatures were measured by using the DSC analysis (SDT-Q600 Simultaneous TGA/DSC, TA Instruments, Germany), and thermal conductivities of the investigated alloys were determined by using the xenon-flash method on TA Discovery Xenon Flash (DXF) 500 instrument (TA Instruments, Germany). The experimental procedure is explained in detail in the previous paper [30].…”

“…The results of conducted analyses are given in Table 7. The total uncertainty for the determined thermal conductivity is estimated to be ±8 % [30]. The obtained results show that the thermal diffusivity and thermal conductivity of the investigated Bi-Sn alloys gradually decrease with increasing the Bi content due to bismuth being one of the metals with the lowest thermal conductivity [36].…”

Lead-free solders have become a main focus of the electronic industry in recent years, because of the high toxicity of lead. Alloys based on the Sn-Bi system figure as potential replacements for Sn-Pb alloys in soldering due to favorable properties and low cost. One of the main advantages of these alloys are low melting temperatures, while additional advantages include good compatibility with substrates, low process temperature, high reliability, and potential applications in conjunction with reduced graphene oxide nanosheets as thermal interface materials. In this paper, characterization of microstructural and thermal properties as well as hardness measurements of seven alloys of different Sn-Bi compositions are performed. Structural properties of the samples were analyzed using optical microscopy and scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDS). Thermal conductivity of the samples was investigated using the xenon-flash method, and phase transition temperatures were measured using the differential scanning calorimetry (DSC) analysis.

Phase transformations and thermal conductivity of three In-Ag alloys with 5, 15, and 45 wt.% of Ag were experimentally investigated in the present work. Phase transition temperatures were measured using differential scanning calorimetry (DSC). DSC heating scans were compared with the equilibrium and non-equilibrium solidification paths, calculated by using optimized thermodynamic parameters from literature and calculation of phase diagrams (CALPHAD) method. The flash method was employed for the determination of thermal diffusivity and thermal conductivity of the investigated alloys in the temperature range from 25 to 100 °C. It has been found that an increase in silver content does not lead to an increase in the thermal conductivity of the investigated alloys. Thermal conductivities for all three investigated In-Ag alloys slightly decrease with temperature increasing.
