Effect of Ball Milling Time for Powder Mixing on the
In the present study SiC AlN powder mixtures were prepared by ball milling for 1 to 300h and subsequent HIPing at 2073 to 2173K for 2h. The formation of solid solutions was found to be enhanced in fine mixed powder mixture. Variation of the thermal and mechanical properties for the HIPed compacts was found to depend on the ball milling time. Nhận giá Get Price Whatsapp
sic powder ball milling
Extensive ball milling facilitated effectively the formation of solid solutions by improvement in mixing homogeneity and pulverization of the SiC and AlN powders. Thermal conductivity of the HIP sintered SiC AlN powder mixtures decreased remarkably with ball milling time mainly because of the enhanced formation of solid solutions. Nhận giá Get Price Whatsapp
