Anomalous eutectics in the solidification structure of undercooled Ni–18.7 at.% Sn eutectic alloy were examined by optical metallography and electron backscattered diffraction. It was revealed that α–Ni particulates are, in principle, randomly distributed in the anomalous eutectics in the undercooling range investigated. Another eutectic phase, β–Ni3Sn, is well orientated at low undercoolings but gradually becomes inconsistent in orientation as undercooling increases, accompanied by an increasing number of grain boundaries in it. As the solidification structure changes from a mixture of anomalous eutectics plus lamellar eutectics to full anomalous eutectics beyond a critical undercooling of 130 K, however, misorientation in the β–Ni3Sn phase disappears completely from the measurement area. Partial remelting of the primary solid was proposed to be the origin of the anomalous eutectic formation, and quantitative analyses were performed.

Abstract INDALLOY 136 is a bismuth-base, eutectic alloy that melts at 136 F (57.8 C). It is used widely in industry because of its low melting temperature and controlled-shrinkage characteristics. It provides the scientist, engineer and technician with an easily castable material that is ready for use soon after it freezes. The alloy can be recovered easily and recycled into new uses any number of times. Among its uses are anchoring parts for machining, proof casting and low-melting solder. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, heat treating, and machining. Filing Code: Bi-24. Producer or source: Indium Corporation of America.

Abstract INDALLOY No. 255 is a fusible alloy that melts at 255 F. This low-melting eutectic alloy provides scientists and engineers with an easily castable material that is ready for use as soon as it freezes. It can be recovered easily and recycled into new uses any number of times. Among its many applications are proof-casting, liquid seals for heat-treating furnaces, non-shrinking patterns and dental models. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, forming, heat treating, and machining. Filing Code: Bi-18. Producer or source: Indium Corporation of America.
