Effect of Primary Deoxidation Products of Al_2O_3,ZrO_2, Ce_2O_3 and MgO on TiN Precipitation in Fe-10mass/100Ni Alloy

摘要

Effect of Al_2O_3,ZrO_2, Ce_2O_3 and MgO particles with mean diameter of 0.8 to 1.5μm on the precipitation of TiN during solidification and holding at 1400deg C has been studied in a Fe-10mass/100Ni alloy. The values for the number of particles per unit area, N_A, and the mean diameter, d_a, of TiN and TiN+M_xO_y (M=Al, Zr, Ce, and Mg) particles have been measured as a function of initial contents of Ti(50 to 990 mass ppm) and N (200 to 290 mass ppm), and holding time (0 and 60 min).
