Analysis of thermo-mechanical behavior for ceramic powder during cold and warm compaction processes / Mohd Sani Jamailudin and Mohamed Azwa Hasshim

The thermo-mechanical behavior of alumina ceramic powder during cold and warm compaction processes was studied. The mechanical characterization such as green density, sintered density and linear shrinkage of the sintered compacted alumina ceramic powders were included in the study. The effect of sin...
