Study of Preparation of Ni-Al alloy Aircraft Material by SPS via Grey Clustering.

Spark plasma sintering (SPS) is an important method of preparation of Ni-Al alloy high performance aircraft material. This paper adopted grey cluster analysis to estimate the Ni-AI alloy aircraft material with different chemical compositions. The cluster properties were judged according to the summary of three grey degrees. The evaluating results can be used for guiding experiment technology and future application in actual production.
