Effect of die compaction pressure on densification behavior of molybdenum powders

Two grades of commercially available ultrafine molybdenum powders are investigated for their compaction and densification behavior. Dilatometer studies were performed on the two powders compacted at different pressures, and the results were rationalized using master sintering curve concepts. The study gave insight into the sintering mechanism of molybdenum powders. The results were use for developing die compaction and sintering models. Accurate density prediction and design of optimum sintering cycles are outcomes from this study. (C) 2005 Elsevier Ltd. All rights reserved.
