Microstructural characteristics and electrical resistivity of rapidly solidified Co-Sn alloys
Abstract The rapid solidification behavior of Co-Sn alloys was investigated by melt spinning method. The growth morphology of αCo phase in Co-20%Sn hypoeutectic alloy changes sensitively with cooling rate. A layer of columnar αCo dendrite forms near the roller side at low cooling rates.

520 | |a Abstract The rapid solidification behavior of Co-Sn alloys was investigated by melt spinning method. The growth morphology of αCo phase in Co-20%Sn hypoeutectic alloy changes sensitively with cooling rate. A layer of columnar αCo dendrite forms near the roller side at low cooling rates. This region becomes small and disappears as the cooling rate increases and a kind of very fine homogeneous microstructure characterized by the distribution of equiaxed αCo dendrites in $ γCo_{3} $Sn matrix is subsequently produced. For Co-34.2%Sn eutectic alloy, anomalous eutectic forms within the whole range of cooling rates. The increase of cooling rate has two obvious effects on both alloys: one is the microstructure refinement, and the other is that it produces more crystal defects to intensify the scattering of free electrons, leading to a remarkable increase of electrical resistivity. Under the condition that the grain boundary reflection coefficient r approaches 1, the resistivity of rapidly solidified Co-Sn alloys can be predicted theoretically. | ||

The growth morphology of αCo phase in Co-20%Sn hypoeutectic alloy changes sensitively with cooling rate. A layer of columnar αCo dendrite forms near the roller side at low cooling rates. This region becomes small and disappears as the cooling rate increases and a kind of very fine homogeneous microstructure characterized by the distribution of equiaxed αCo dendrites in $ γCo_{3} $Sn matrix is subsequently produced. For Co-34.2%Sn eutectic alloy, anomalous eutectic forms within the whole range of cooling rates. The increase of cooling rate has two obvious effects on both alloys: one is the microstructure refinement, and the other is that it produces more crystal defects to intensify the scattering of free electrons, leading to a remarkable increase of electrical resistivity. Under the condition that the grain boundary reflection coefficient r approaches 1, the resistivity of rapidly solidified Co-Sn alloys can be predicted theoretically. rapid solidification (dpeaa)DE-He213 dendritic growth (dpeaa)DE-He213 eutectic growth (dpeaa)DE-He213 electrical resistivity (dpeaa)DE-He213 Nan, Wang verfasserin aut Bingbo, Wei verfasserin aut Enthalten in Chinese science bulletin Beijing, China : Chinese Acad. of Sciences, 1997 49(2004), 21 vom: Nov., Seite 2242-2247 (DE-627)341897809 (DE-600)2069521-4 1861-9541 nnns volume:49 year:2004 number:21 month:11 pages:2242-2247 https://dx.doi.org/10.1360/04ww0066 lizenzpflichtig Volltext GBV_USEFLAG_A SYSFLAG_A GBV_SPRINGER GBV_ILN_20 GBV_ILN_40 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_110 GBV_ILN_120 GBV_ILN_161 GBV_ILN_266 GBV_ILN_285 GBV_ILN_293 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2005 GBV_ILN_2007 GBV_ILN_2009 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2018 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2039 GBV_ILN_2044 GBV_ILN_2055 GBV_ILN_2059 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2070 GBV_ILN_2086 GBV_ILN_2106 GBV_ILN_2108 GBV_ILN_2111 GBV_ILN_2112 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2118 GBV_ILN_2119 GBV_ILN_2122 GBV_ILN_2129 GBV_ILN_2143 GBV_ILN_2144 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2153 GBV_ILN_2188 GBV_ILN_2190 GBV_ILN_2232 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4313 GBV_ILN_4328 GBV_ILN_4333 30.00 ASE AR 49 2004 21 11 2242-2247 |

Microstructural characteristics and electrical resistivity of rapidly solidified Co-Sn alloys |
abstract |
Abstract The rapid solidification behavior of Co-Sn alloys was investigated by melt spinning method. The growth morphology of αCo phase in Co-20%Sn hypoeutectic alloy changes sensitively with cooling rate. A layer of columnar αCo dendrite forms near the roller side at low cooling rates. This region becomes small and disappears as the cooling rate increases and a kind of very fine homogeneous microstructure characterized by the distribution of equiaxed αCo dendrites in $ γCo_{3} $Sn matrix is subsequently produced. For Co-34.2%Sn eutectic alloy, anomalous eutectic forms within the whole range of cooling rates. The increase of cooling rate has two obvious effects on both alloys: one is the microstructure refinement, and the other is that it produces more crystal defects to intensify the scattering of free electrons, leading to a remarkable increase of electrical resistivity. Under the condition that the grain boundary reflection coefficient r approaches 1, the resistivity of rapidly solidified Co-Sn alloys can be predicted theoretically. |
