Fig. 1 a and b. Austenitic grains with intense intergranular precipitates and a lamellar constituent were observed
Fig. 2. Magnetisation vs. field dependence recorded at room temperature for as- as-sintered 304L N and 316L N and for aged 304 L N at 875 1C for 8 h.
Fig. 3 b compared to Fig. 3 a shows that not all the lamellar constituent of 304L N is magnetically etched
Fig. 6. EDS line profile of (a) lamellar constituent of as-sintered 304L N and (b) precipitate of as-sintered 304L N.
