FIGURE 16.22 (a) Relative grain size versus relative density for a grain growth exponent g = 2 as a function of the log-normal size distribution width parameter, cr. Taken from Chappell et al. [47]. (b) Experimental grain size (GS) divided by initial particle size (PS() 0.3 pm) versus relative density for — monodisperse T1O2 [53] (cr = 0.1), — TiOj [54] ([Pg.817]

FIGURE 16.30 Schematic of grain size distribution at various times for normal and abnormal grain growth. For abnormal grain growth a bimodal size distribution is produced from initially a monomodal size distribution.
