title: [Effects of Co, Mo and Cu on the fluidity of 80Ni-20Cr alloy].
abstract: An attempt was made to determine the castability of Nickel-Chromium alloys which contained an additional element. 80 Ni-20 Cr binary alloy was prepared in the argon atmosphere and saved as control alloy. Then three sets of different components alloys, each set contains different composition (5, 10, 15%) of Co, Mo, or Cu to the control alloy, were prepared and used as test materials. The fluidity was evaluated by casting them into the cylindrical coil shaped mould cavity and examining their ability to flow into the mould cavity before solidification took place. The fluidity of Nickel-Chromium alloy was not changed by addition of Co or Mo up to 5%. However, the fluidity was significantly decreased by addition of Cu, or Mo when its concentration was increased over 5%. Thus, from the viewpoint of castability a large amount of Mo or Cu should not added to the Nickel-Chromium alloy.
