Crystallization of CoSi₂-Si Eutectic Composites

Abstract:

The subject of the study is the composite material of CoSi2-Si eutectic composition. The influence of crystallization speed on microstructure was examined. The ingots were obtained using Bridgman method. Three different pulling down speeds of crucibles with melted charges were applied. The prepared samples were subjected to metallographic, X-ray, TEM techniques and mechanical examinations in order to characterize the properties of the studied composite material. It was shown that the favourable crucible pulling down speed to obtain CoSi2-Si fibrous eutectic microstructure was 3mm/h.
