- 論文の詳細を見る
Real-time X-ray topography has been applied to a study of dendritic growth. Unidirectional melting and solidification processes of Al-Mg single crystals containing 0.5, 2.0 and 4.0 at%Mg were observed by real-time X-ray topography. Observations have been made on the following subjects: (1) sequential growth and morphology of dendrite arms during solidification as a function of the growth rate; (2) morphological changes of dendrite arms as a function of the Mg content; (3) morphological changes and solute redistribution during cooling and isothermal annealing after solidification; and, (4) observation of the melting process of a previously grown dendrite. Some valuable information which cannot be obtained by the conventional "ex post fact" method has been obtained by real-time X-ray topography.
