Abstract

Seven Cu substances containing(up to 30%)experimental Ni-Cr alloys were prepared and the castability of the alloys were evaluated by the mesh grid pattern.This method employs reproducible specimen patterns and the castability value of metals and alloy is readily determined.With the increase to Cu content, the solidus and liquidus points of the Ni-Cr alloys shifted downward, and the castability values of the Ni-Cr alloys increased with increasing Cu content.Mechanical properties of Ni-Cr alloys gradually increased with increases in the Cu content in the range from 0 to 20%.
