Microstructure and mechanical properties of directionally solidified Al2O3/YAG binary eutectic ceramic prepared with induction heating zone melting

Microstructural Stability and High Temperature Strength of Directionally Solidified Al2o3/Er3al5o12/Zro2 Eutectic Ceramics

“…Electronic copy available at: https://ssrn.com/abstract=4375638 P r e p r i n t n o t p e e r r e v i e w e d crucible movement rate was 20 mm/h. Since the moving speed of the crucible was small enough, the moving speed of the crucible was also considered to be the growth speed of the sample [9]. The temperature gradient of high frequency induction zone melting method could reach 10 3 K/cm [6].…”

“…on the eutectic growth mechanism, microstructure morphology (three-dimensional interpenetrating Chinese character, lamellar, fibrous, colony, cellular) and size (or eutectic spacing), and finally on the mechanical properties (hardness, fracture toughness, bending strength, etc.) [7][8][9]. However, they rarely involve tensile strength and high temperature strength, especially the tensile strength at high temperature, let alone the change of microstructure and high temperature tensile strength with heat treatment temperature and time.…”
