研究了两种商用超细钼粉的致密化和致密化行为。对在不同压力下压制的两种粉末进行了膨胀仪研究，并用主烧结曲线概念对结果进行了合理的解释。对钼粉的烧结机理进行了深入的研究。研究结果可用于开发模压成型和烧结模型。准确的密度预测和最佳烧结循环的设计是本研究的成果。(C)2005爱思唯尔有限公司。保留所有权利。
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.
