Fig. 8 Statically recrystallized grain size. Predicted grain size ranges from ASTM 5.5 at the center to 6.0 near the edge, several millimeters beneath the surface. The 1s indicate regions of very slightly refined grain size or the original coarse grain size (low ASTM grain size number), while More

Fig. 9 Dynamically recrystallized grain size. Predicted grain size ranges from ASTM 3.5 at the center to 7.0 near the edge, several millimeters beneath the surface. The 1s indicate regions of the original coarse grain size (low ASTM grain size number), while the 2s indicate fine grain size More

Fig. 4 Plot of grain size vs. pore size during sintering to show the conditions under which grain growth can cause a breakaway from the pores, eventually leading to inhibited densification. Desirable sintering pathways avoid the breakaway condition by sustaining pore shrinkage at low More

Fig. 24 Grain-size distribution in zone-refined iron during isothermal grain growth at 650 °C (923 K), using a scalar-adjusted grain diameter for each specimen. The plot indicates that the grain-size distribution remains essentially unchanged during normal grain growth. More
