Investigation on Microstructure and Mechanical Properties of Directional Solidified DZ417G Alloy with Different Proportion of Recycling Alloy

Abstract:

The DZ417G alloy with different proportion of recycling material was fabricated by directional solidification, and its microstructure and mechanical properties were investigated. The results show that the microstructure of the directionally solidified alloy changes little, which indicates the recycling material has little effect of on the alloy. However, the ductility of the directional solidified alloy with different proportion of recycling material changes greatly. With the increase of the recycling materials, the mechanical properties of the alloy decrease firstly and then increase a little and decrease at last. But the strength of the alloy almost has no change. The alloy with 70%recycle material has the relative better mechanical properties.
