Abstract

The welding of 45 steel and 0Crl8Ni9 stainless steel was done under different Spark Plasma Sintering (SPS) parameters, and the microstructure and micro-hardness of the joints were examined. We optimized SPS parameters namely welding temperature, holding time and axial pressure through grey relational analysis with the considerations of multiple performance characteristics including width of diffusion zone, micro-hardness in diffusion zone and micro-hardness in weld zone. The result indicated that the SPS welding process could be improved effectively through this approach, which was useful in the optimization of SPS parameters for dissimilar steel welding.

Abstract

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.
