Investigations in the compaction and sintering of large ceramic parts

The influence of micropore size on the mechanical properties of bulk hydroxyapatite and hydroxyapatite scaffolds

“…1). To lessen the effect of tapering commonly seen in compacted samples with high aspect ratios (Bortzmeyer, 1992;Chen and Kim et al, 2007), the cylindrical samples were inverted and re-pressed at the same pressure. After the sintering schedule described above (Step 3, Fig.…”

Shrinkage characteristics studies on conventional sintered zirconia toughened alumina using computed tomography imaging technique

“…The unified model using finite element analysis method also predicts more shrinkage at the top and lower shrinkage at the bottom. As predicted by Chen et al [38], a conical shape is formed by diameter changes along the length after sintering of cylindrical shaped parts. The shrinkage at 1600°C of 2 mm is more compared to 1400°C and is very low for 1200°C with 0.3 mm shrinkage which is in accordance with the reported literature [39].…”

Parameter optimization of Al-SiC metal matrix composites produced using powder-based process

“…Since, there are two responses, weighted method with unit weights is adopted to form a single objective function Z as given in Eqn. (3).…”

“…The investigations related to the compaction and sintering of large ceramic parts was done by Chen et al [3]. It was observed that the multi-step sintering process reduced the phenomenon of cracking around the places with highest density.…”
