X-ray tomography analysis of aluminum alloy powder compaction
文献摘要：
Aluminum alloy green compacts obtained by single-action compaction in lubricated and unlubricated dies were investigated by X-ray tomography.For the pur-pose of obtaining the relationship between the density of green compact and the gray value of reconstructed images,linear fitting was performed.The results show that these data have excellent linear relationship.Then,a new method for analysis of compaction process was presented in this paper.Detailed quantitative analysis of the density and compressive pressure distribution in green compacts was performed.The compressive pressure transmitted ratio and friction index were also discussed.It is found that the lubricated die wall has better effects on the density homogeneity at lower applied compressive pressure.Dur-ing compaction process,the densification of powder par-ticles in the die mainly occurs in the lower part of the green compact and the factor which mainly influences the friction between die wall and green compact is the applied com-pressive pressure.
