WebThe SiC powder ITRI-2 with the smaller D90 grain size exhibits a much faster overall sintering. The double growth rate using the SiC powder ITRI-2 (small SiC grains) compared to the SiC powder ITRI-1 (large SiC grains) during nominally identical growth process parameters could be partially related significant different WebCopper grain growth and strength Pure copper (typically >99.9%) is a great electrical conductor, and in some applications its strength is important as well. Copper grain growth closely follows Feltham's observation, i.e. D2-D2 = kot exp (-Ho/KT). For this problem, ignore temperature dependence and use D.D. ? = constant.
