Abnormal grain growth and microcracking in boron carbide

Journal Article · · J. Am. Ceram. Soc.; (United States)
; ;
Boron carbide compacts sintered between 2220/sup 0/ and 2250/sup 0/C showed abnormal grain growth that was associated with twinning and microcracking. The twin direction was (011). The microcracking was linked to thermal expansion anisotropy determined by high-temperature lattice constant measurement.
