These grains show abnormal growth. When sintered at 2020 degrees C, the grains develop round edges and corners, and the grain growth is nearly normal. Such a grain shape change indicates that the interface between the grains and the liquid matrix undergoes roughening transition with temperature increase. The interface roughening transition is reversed when a specimen initially sintered at 2020 degrees C is heat treated again at 1400 degrees C.
