  • Electrical and Thermal Characteristics of Pb-Free Sn-Zn Alloys for an AC-Low Voltage Fuse Element
    Materials Transactions, Vol. 48, No. 5 (2007) pp. 1105 to 1112 #2007 The Japan Institute of Metals EXPRESS REGULAR ARTICLE Electrical and Thermal Characteristics of Pb-Free Sn-Zn Alloys for an AC-Low Voltage Fuse Element Kazuhiro Matsugi1, Gen Sasaki1, Osamu Yanagisawa1, Yasuo Kumagai2 and Koji Fujii2 1Department of Mechanical Materials Engineering, Hiroshima University, Higashi-Hiroshima 739-8527, Japan 2The Chugoku Electric Power Co. Inc., Hiroshima 730-8701, Japan The temperature dependence of specific resistivity and thermal conductivity for some Sn-Zn alloys was measured to use their values in electrical and thermal calculations on the basis of Ohm’s and Fourier’s laws, in order to obtain the temperature-distribution in lead-free fuse elements of electric power line. The interaction between microstructures and their properties was also investigated in Sn-Zn alloys. Specific resistivity and thermal conductivity could be estimated as a function of temperature and alloy composition in the compositional ranges classified from the standpoint of continuity or non-continuity of constituent phases such as primary Zn, Sn-solid solution and eutectic in microstructures of Sn-1 to 100Zn alloys. In the proposed estimations, not only volume fraction of Zn and Sn-solid solution phases but morphologies of both phases were considered in Sn-Zn alloys.

Why It’s Important The world around you is com- posed mainly of compounds. The properties of each com- pound are based on how the compound is bonded. The salts dissolved in Earth’s oceans and the compounds that make up most of Earth’s crust are held together by ionic bonds. Visit the Chemistry Web site at chemistrymc.com to find links about ionic compounds. The rock surface, the climbers’ equipment, the atmosphere, and even the climbers are composed almost entirely of compounds and mixtures of compounds. 210 Chapter 8 210-239_Ch08-866418 5/8/06 5:22 PM Page 211 DISCOVERY LAB An Unusual Alloy ost metals that you encounter are solids.

Chapter 3 Historical introduction on fusible alloys Copyright: Jacques Jumeau 1st edition 2018/08/22 Copy is allowed, provided you cite the origin: Ultimheat Museum 1 Update 2019/02/15 History of threaded pipe connections The history of low temperature fusible alloys is a succession of stages, spread over two millennia, according to the successive discoveries of metals Roman waterpipe, made of soldered lead strips (Museum of Arles et de la Provence antique ( extraite de https://commons.wikimedia.org/w/index.php?curid=10214375) and experiments. The 183°C limit: The binary alloys of lead and tin The earliest known piece made of lead and tin alloy seems to be an Egyptian vase found in Abydos, dated around 1400 BC. During the Roman Empire, lead was used for the construction of water pipes. Melting at 325°C, it was easily melted into strips. As it does not self-weld, it was a mixture of lead and tin that was used to weld the strips rolled together into hoses. Although they did not have temperature measuring devices, the Romans had noticed that by adding a certain percentage of tin (melting at 235°C) imported from Cornwall to the lead, the mixture melted at a temperature less than that of lead. In his Natural History, Pliny the Elder, in the course of the first century, gave the formula for welding the lead tubes: two parts of lead for a part of tin. (Melting range of the alloy 66.7-33.3: 185-250°C).

  • 1 Temperature and Rate Dependent Constitutive Behaviors of Low Melt Field's Metal Quang-Kha Nguyen, Fanghang Deng, Pu Zhang*
    Temperature and Rate Dependent Constitutive Behaviors of Low Melt Field's Metal Quang-Kha Nguyen, Fanghang Deng, Pu Zhang* Department of Mechanical Engineering, State University of New York at Binghamton, Binghamton, NY 13902 Abstract Low melting point metals such as Field’s metal and gallium are increasingly used as transition phases in stiffness-tuning soft materials and devices. Nevertheless, there is a knowledge gap on the fundamental constitutive behaviors of metals with melting points below 100℃. This letter reports the stress-strain relationships of Field’s metal at various temperatures and strain rates. This metal has the lowest melting point among metals whose constitutive behaviors have been studied systematically. Experimental results indicate that Field’s metal exhibits a strain-softening behavior, in oppose to the strain-hardening behaviors of most engineering metals and alloys. A modified Johnson-Cook model is devised in this letter to describe the constitutive behaviors of Field’s metal. The proposed model will facilitate the design and analysis of functional materials and structures consisting of Field’s metal. Keywords: Liquid metal; Low melting point alloy; Field’s metal; Constitutive model 1. Introduction Low melting point metals (LMPM) [1] have been employed to fabricate functional materials and structures [2–11] with tunable stiffness, shape memory effect, self-healing behaviors, good thermal/electrical conductivity, etc. The most commonly used lead-free LMPMs include gallium (melting point Tm = 30℃) and Field’s metal (Tm = 62℃), which are also called liquid metals sometimes [1]. The most prominent feature of LMPMs is their solid- liquid phase transition at relatively low temperatures, e.g.

  • Fire Detection Fusible Links
    9 ULTIMHEAT FIRE DETECTION FUSIBLE LINKS A fusible link is a mechanical part that breaks at a preset temperature, they are used in fire detection system to open or close door, dampers, vents etc..., if ambient temperature rise upon a certain value. The professional solution: an extended, rational, and consistent range of products Technical catalogue for R&D department Edition 27/02/2013 E-Mail: [email protected] Web: www.ultimheat.com E-Mail : [email protected] Web: www.ultimheat.com Historical and technical introduction of fusible alloys and fire safety fusible links The first set of low temperature melting alloys was reported by Isaac Newton in 1701 for use as temperature standards. In 1753, the French scientist Claude Geoffroy Le Jeune discovered Bismuth, previously confused with lead. However, he died before completing his research on the metal. A set of low melting Bi/Pb/Sn alloys of varying composition were reported posthumously in 1772 by the German pharmacist, Valentin Rose the Elder (1736-1771), and are commonly referred to as “Rose’s Metal,” In 1775, the French chemist Jean Arcet provided to the Royal Academy of Sciences a report of his experiences on a fusible alloy of lead, bismuth and tin, which had the characteristic of melting at the water boiling temperature. A set of more than ten compositional variations for this system was reported and are known collectively as “D’Arcet’s Alloys” The first application of one of these alloy melting at 98 °, made of three parts of tin, eight parts of bismuth and five parts of lead was the manufacturing of stereotype printing plates.

  • Historical and Technical Introduction of Fusible Alloys and Fire Safety Fusible Links
    Historical and technical introduction of fusible alloys and fire safety fusible links Historical and technical introduction of fusible alloys and fire safety fusible links J.Jumeau 20121030 Historical and technical introduction of fusible alloys and fire safety fusible links P 1/2 The first set of low temperature melting alloys was reported by Isaac Newton in 1701 for use as temperature standards.

But quickly, due to the development of steam boilers and steam engines, a new application was found as the ultimate safety device in steam boilers. To overcome the frequent explosions occuring in early steam engines, the fusing plugs were invented, opening a safety valve when the steam temperature became too high.
