A novel melt falling-drop quenching method with rapid cooling rate is carried out to prepare the Al2O3/Er3Al5O12 nanoeutectic ceramic based on laser floating zone melting. The regular eutectic structure with minimum interphase spacing of 30nm is obtained, which is much smaller than previous reports. The continuous transition of irregular eutectic to regular eutectic and to amorphous structure is found...
Directionally solidified Al2O3/Er3Al5O12(EAG) eutectic in situ composites are prepared by laser floating zone melting (LFZM) to investigate the solid–liquid interface characteristic and growth rate range under non-equilibrium solidification conditions. The solid–liquid (S–L) interface is in situ obtained by rapidly quenching, and its microstructure morphology and primary phase based on different eutectic...
