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 ...
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 ...
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 ...
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 ...
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 ...
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 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 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 ...
