摘要

The recast layer is an undesirable surface residue after the electric discharge machining of materials, which would affect the following brazing process and cause microstructure and property degradation. In this study, the effects of the recast layer composed of carbon-containing gamma solid solution on the microstructure and mechanical properties of Ni-based single crystal superalloy were investigated. After brazing, the formation of carbo-borides, borides, and Kirkendall voids near the joint interface could be eliminated via the aging process to recovery the microstructure and property.
