إنموذج تأثير الحجم الحبيبي في المرحلة النهائية لتلبيد Al2O3

Abstract EN

This research studies the effect of grain size for the final stage in sintering AI2O3 .The experimental results for a- Al2O3 powder are modeled using ( L -Regression ) technique in order to study the effect grain size distribution on densification rate using four kinds for the initial particle size which were ( 1.44 , 2.54 , 0.7-2.54 ,1.15-3.53 ) |im , and for sintering time (0-241) min.

The mathematical simulation for grain size changing shows that the densification rates boots up as the grain size goes lower, this was due to the increase of contact area between the grains.
