摘要：

The microstructure of porous composite compacts obtained by hot isostatic pressing of superalloy powder mixed with 18% volume fraction of alumina inclusions has been quantitatively analysed. For every specimen, the three constituent phases-metal particles, inclusions and pores-were separated. Separation of individual metal particles was also achieved-except for the densest specimen-from which parameters characterizing the size, shape and connectivity of metal particles were measured. The interphase correlation functions provided the most relevant information, which allowed discussion of the evolution of the microstructure of the material and of the role of inclusions during the consolidation process.
