Effect of Sb Addition on the Solidification of Deeply Undercooled Ag-28.1 wt. % Cu Eutectic Alloy
Ag-28.1 wt. % Cu eutectic alloy solidifies in the form of eutectic dendrite at undercooling above 76 K. The remelting and ripening of the original lamellar eutectics result in the formation of the anomalous eutectics in the final microstructure. The addition of the third element Sb (0.5 and 1 wt. %) does not change the growth mode, but enlarges the volume fraction of anomalous eutectics because...
متن کاملDirectional solidification of the eutectic LiF-LiYF4 using Bridgman and micro-pulling down techniques: Microstructural study and some properties
The eutectic LiF−LiYF4 has been solidified by Bridgman and micro-pulling down (mPD) at pulling rates from 4 to 300 mm/h. The microstructure changes from a coupled, interpenetrated-like one to macrofaceted colonies composed of an approximately triangular arrangement of LiF fibers inside the LiYF4 matrix as the pulling rate increases. The cross-over pulling rate is around 3 times larger for the m...
متن کاملHOT CRACK FORMATION IN PURE CU AND CU-30%ZN ALLOY DURING IN SITU SOLIDIFICATION
The hot cracking susceptibility can be determined by establishing the transition temperature between brittle and ductile fracture at high temperature tensile testing of in situ solidified samples. High temperature tensile properties were determined for commercial cathodic pure Cu and Cu- 30%Zn alloy. The transition temperatures for pure Cu and Cu-30%Zn were evaluated from ultimate tensile stres...
متن کاملShape Memory Properties in Cu-Zn-Al Alloy
In this research a Cu-Zn-Al alloy is produced by melting the raw materials in an electric resistance furnace and then pouring it into a steel mould. The optimum way to achieve the final analysis in the hypo-eutectoid range is determined and the influence of the alloying element, Ti on the grain size and the shape memory properties of the samples are investigated. Solution treatment (done at 850...
