Interflake spacings and undercoolings in Al-Si irregular eutectic alloy
(ELSEVIER SCIENCE SA, 2004)
Aluminium-silicon irregular eutectic alloy was melted in a graphite crucible in vacuum. This alloy was directionally solidified at a constant growth rate, V (8.3 mum/s) and at different temperature gradients, G (2.0-7.8 ...
Effect of growth rates and temperature gradients on the spacing and undercooling in the broken-lamellar eutectic growth (Sn-Zn eutectic system)
(ASM INTERNATIONAL, 2003)
The Sn-Zn system has a eutectic structure of a broken lamellar type. Dependence of the broken-lamellar spacing lambda and the undercooling DeltaT on V and G were investigated, and the relationship between them was examined. ...
Effect of growth rate and composition on the primary spacing, the dendrite tip radius and mushy zone depth in the directionally solidified succinonitrile-Salol alloys
(ELSEVIER SCIENCE BV, 2003)
The succinonitrile (SCN)-Salol alloys for four different concentrations Salol were unidirectionally solidified for five different growth rates in a constant temperature gradient. The microstructure parameters, viz., the ...
Effect of growth rates and temperature gradients on the lamellar spacing and the undercooling in the directionally solidified Pb-Cd eutectic alloy
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
Lead-cadmium of high (99.99%) purity eutectic alloy was melted in a graphite crucible under vacuum atmosphere. These regular eutectic alloys were directionally solidified upward with a constant growth rate of 8.3 mum/s, ...
Effect of the temperature gradient, growth rate, and the interflake spacing on the microhardness in the directionally solidified Al-Si eutectic alloy
(ASM INTERNATIONAL, 2003)
An alloy of composition Al-12.6 wt.% Si was prepared using metals of 99.99% purity. Weighed amounts of aluminium and silicon were melted in the vacuum-melting furnace. This irregular eutectic alloys were directionally ...
Dependency of the dendritic arm spacings and tip radius on the growth rate and composition in the directionally solidified succinonitrile-carbon tetrabromide alloys
(ELSEVIER SCIENCE BV, 2005)
Succinonitrile (SCN)-carbon tetrabromide (CTB) alloys for different concentrations of CTB (C(0)) were unidirectionally solidified with a constant temperature gradient (G = 7.5 K/mm) at different growth rates (V = 6.5-103.5 ...
Solid-liquid interfacial energy in the Al-Ti system
(ELSEVIER SCIENCE BV, 2004)
The equilibrated grain boundary groove shapes for the Al-Ti peritectic system were directly observed. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient for solid Al in Al-Ti solution has been ...
Effect of growth rate and lamellar spacing on microhardness in the directionally solidified Pb-Cd, Sn-Zn and Bi-Cd eutectic alloys
(SPRINGER, 2004)
Lead-cadmium, Zinc-tin and Bismuth-cadmium of (99.99%) high purity eutectic alloys were melted in a graphite crucible under vacuum atmosphere. These eutectic alloys were directionally solidified upward with a constant ...
